From 7730ca78675b5bc05f2ec0fec05693f928957087 Mon Sep 17 00:00:00 2001 From: Hanwen Cheng Date: Mon, 25 May 2026 11:46:55 +0800 Subject: [PATCH 01/36] =?UTF-8?q?m1:=20AgentKeys=20MCP=20server=20?= =?UTF-8?q?=E2=80=94=20Phase=201=20(closes=20#107)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `crates/agentkeys-mcp-server/` — the integration surface that makes the Phase 0 backend (broker, memory worker, audit worker, signer) legible to MCP-speaking LLM hosts (xiaozhi-server, Volcano Ark). Tools (10 total): - 7 active: identity.whoami, memory.{get,put}, permission.check, cap.{mint,revoke}, audit.append - 3 schema-only: delegation.{grant,revoke}, approval.request — return `{"error":"not_implemented_in_v1","scheduled_for":"M4","spec_url":...}` Auth (HTTP transport): `Authorization: Bearer ` + per-call `X-AgentKeys-Actor: `. Wrong token → 401, missing actor → 403, cross-actor param → -32003. Policy engine for permission.check is deterministic — pure function, no LLM, no I/O. Locks in the storyboard's Act 2 wording (`cap=500, requested=600, period=daily`). Tests: 31/31 green (17 unit + 6 HTTP auth + 3 stub shape + 5 three-act). Clippy clean. Live binary smoke-tested.

Phase 0's existing + `crates/agentkeys-mcp/` (Rust JSON-RPC over stdio) was the + pre-existing proof. Issue's "Rust as fallback" clause covers it. +2. **Backend trait.** Production uses `HttpBackend` (reqwest); tests use + `MockBackend`. The trait stays narrow — one method per backend + operation, opaque cap-token blob, no shared DB. +3. **Deterministic policy engine.** `permission.check` lives in + `policy.rs`. Pure function, no I/O, no LLM. The storyboard's Act 2 + wording (`cap=500, requested=600, period=daily`) is locked in by a + unit test in `policy.rs`. +4. **Cap.revoke is a graceful stub.** Broker `/v1/revoke/cap/:id` lands + in M4 (paired with vendor portal #114). M1 returns + `{ok:true, revocation:"local_only", note:"..."}` so the parent UI + can render the verdict immediately. Swap to the real call when the + broker endpoint exists; the tool's wire format does not change. +5. **Namespace at request body for M1.** Per #108 partial deferral — the + namespace travels in the MemoryGet/Put body, not in the signed + CapPayload. The worker accepts it as metadata; cryptographic binding + to the cap lands in M4. + +## 3.

Assertions (all green): ✓ initialize handshake → name=agentkeys-mcp-server v0.1.0 ✓ tools/list → all 10 expected tools ✓ Act 2 — deterministic deny, storyboard wording verbatim ✓ Act 1 — memory.get(travel) returns Chengdu fixture ✓ Act 3a — cap.revoke records in-memory (M1 stub) ✓ Act 3b — audit.append returns envelope_hash ✓ schema-only stub → MCP error: not_implemented_in_v1 This closes the protocol-layer half of the goal: when this script passes, xiaozhi-server's MCP client works. Remaining gaps are LLM tool-choice, MagicLick hardware, and live broker deploy — all outside the MCP server boundary. Doc fixes from reading xiaozhi-server source at 7f73dae: - Config path is `data/.mcp_server_settings.json` (leading dot + data/ prefix) — the root-level file is template-only and not read at runtime. Both README and runbook §B.6 had it wrong. - `"transport": "streamable-http"` is REQUIRED. Default is SSE (sse_client) — our server is POST/JSON, not SSE. - Headers under `headers` round-trip unchanged through mcp_client.py → X-AgentKeys-Actor + X-AgentKeys-Session-Bearer work. Runbook §B.11 now splits "verified — automatable" from "operator- driven — needs hardware/account/deploy", instead of one undifferenti- ated "known gaps" list. --- crates/agentkeys-mcp-server/README.md | 16 ++- docs/spec/plans/issue-107-mcp-demo-runbook.md | 59 ++++++++- .../spec/plans/issue-107-mcp-server-phase1.md | 17 ++- scripts/mcp-demo-mode-b-protocol.sh | 117 ++++++++++++++++++ 4 files changed, 198 insertions(+), 11 deletions(-) create mode 100755 scripts/mcp-demo-mode-b-protocol.sh diff --git a/crates/agentkeys-mcp-server/README.md b/crates/agentkeys-mcp-server/README.md index 77e60f8..41ffafe 100644 --- a/crates/agentkeys-mcp-server/README.md +++ b/crates/agentkeys-mcp-server/README.md @@ -86,13 +86,17 @@ the vendor onboarding portal. ## xiaozhi-server integration -Add to `mcp_server_settings.json` of xiaozhi-server: +Write to `main/xiaozhi-server/data/.mcp_server_settings.json` (the leading +dot + the `data/` prefix are required — verified against +[`xinnan-tech/xiaozhi-esp32-server`](https://github.com/xinnan-tech/xiaozhi-esp32-server) +commit `7f73dae`, file `main/xiaozhi-server/core/providers/tools/server_mcp/mcp_manager.py`). ```json { "mcpServers": { "agentkeys": { "url": "https://agentkeys-mcp.example.com/mcp", + "transport": "streamable-http", "headers": { "Authorization": "Bearer ", "X-AgentKeys-Actor": "" @@ -102,6 +106,10 @@ Add to `mcp_server_settings.json` of xiaozhi-server: } ``` +The `"transport": "streamable-http"` line is **required** — without it, +xiaozhi-server defaults to SSE (`mcp.client.sse.sse_client`) and our +server's `/mcp` endpoint isn't an SSE endpoint. + For local development with the stdio transport: ```json @@ -115,6 +123,12 @@ For local development with the stdio transport: } ``` +**Protocol-level verification:** the official Anthropic `mcp` Python SDK +(`mcp.client.streamable_http.streamablehttp_client`) — which xiaozhi-server +imports directly — successfully drives this server through the full +`initialize` → `tools/list` → `tools/call` lifecycle.

This commit addresses the P1s and most P2s. Remaining items called out as follow-ups. P1 fixes: 1. Hex32 fixture IDs (was: O_kevin_001 / O_kevin_op / 0xdeadbeef). The real broker validates `0x[0-9a-f]{64}`; old fixtures would have been rejected the moment we switched off in-memory. New fixtures are wire-compatible with the real broker/audit/memory worker. - in_memory.rs `DEMO_ACTOR` / `DEMO_OPERATOR` / `DEMO_DEVICE_KEY_HASH` - mode-A/B/C smoke scripts updated - runbook §A updated 2. Honest namespace claim — the M1 memory worker does NOT enforce namespace cryptographically (the wire field flows through but `s3_key` derives from `(actor, service)` only). Runbook now states this plainly and links to the M4 follow-up against #108. 3. Act 3 proves revocation isn't a rubber-stamp: - InMemoryBackend tracks minted cap nonces. - `cap.revoke(known_nonce)` → ok. - `cap.revoke(unknown_id)` → 404 error. - Mode A/B/C smoke scripts now mint a cap, revoke by its nonce, AND assert that an unknown cap_id is rejected. P2 fixes: 4. Port allocated via ephemeral socket pick (Python `socket`/Ruby fallback). Kill -0 liveness check after spawn so a stale server on a fixed port can't masquerade. 5. JSON-RPC responses parsed via jq or python3 with explicit assertions on `result.isError == false`, `result.structuredContent.*`, `error.code`, `error.data.scheduled_for`. No more substring-grep masking tool isError. 6. `audit_append` envelope_hash is now a real SHA-256 over a deterministic input preimage. Two appends with different content produce different hashes; smoke script asserts this. 7. `jq` listed as accepted alternative; smoke script auto-detects jq vs python3. Runbook Act 3 shows both `jq` and `python3` one-liners side by side. 8. `cargo run` (not hardcoded target/debug/$BIN) so CARGO_TARGET_DIR layouts in CI don't desync from the spawn path. P3 noted as follow-up: 9. Multi-vendor tenancy semantics — memory keyed by `(actor, namespace)` so two vendors using the same actor see each other's data. Out of M1 scope; vendor isolation lands with the vendor portal in M2 (#114). CI integration: `.github/workflows/mcp-server.yml` runs `bash scripts/mcp-demo-mode-a.sh` as a third step in the test job (after cargo test + clippy).

The MCP server connects OUT to a xiaozhi-style mcp-endpoint-server relay as a WebSocket client. The relay forwards MCP JSON-RPC frames between us (the tool) and the xiaozhi cloud (the client). No HTTP listen socket; no per-vendor bearer (relay URL token is the binding); reconnect with exponential backoff 1s..600s (matches xiaozhi's mcp_pipe.py). This is the real production integration path for xiaozhi. With this in place, the original goal's "MagicLick firmware flash" + "LLM provider key" steps are unnecessary: - No firmware flash. The xiaozhi cloud already talks to xiaozhi devices in the wild. We register our MCP server with the cloud via the relay URL; any existing device sees our tools. - No LLM key. The xiaozhi cloud hosts the LLM. We provide tools; the cloud LLM decides when to call them. Why no Docker for the deploy: The broker is already on EC2 with systemd + nginx + TLS via scripts/setup-broker-host.sh. Adding Docker would be new operational surface for no benefit. Both mcp-endpoint-server and the MCP server run as systemd units next to the broker. Native Python + native Rust binary. The existing host runbook is the template. New script: scripts/mcp-demo-mode-d-xiaozhi-endpoint.sh — spins up a mock mcp-endpoint-server that mirrors the real routing exactly: /mcp_endpoint/mcp/?token=X — tool path (our MCP server connects here) /mcp_endpoint/call/?token=X — client path (xiaozhi cloud connects here) Same token pairs tool ↔ client; forwards frames verbatim. Then a fake-client side drives initialize → tools/list → all three acts. All 7 assertions pass. Runbook §B fully rewritten: - Old §B was a draft for the hardware-flash path. Removed. - New §B is the relay path: EC2 systemd deploy of mcp-endpoint-server + agentkeys-mcp-server, register URL with xiaozhi.me agent, run voice prompts on any existing xiaozhi device, no MagicLick toy, no Doubao/Qwen key. - §B.11 explicitly: verified-no-resources-needed (mode A/B/C/D run in CI) vs operator-driven (live broker deploy, xiaozhi account, paired device). Other updates: - README §"xiaozhi MCP-endpoint relay" added. - .github/workflows/mcp-server.yml trigger now includes mode-D path. - Plan §6 references mode D + the relay deploy.

Mode D in the repo verifies this whole loop against a local mock relay, so every layer is exercised before you ever touch a real device. ### B.1 Topology ``` -┌────────────────────┐ audio + WebSocket ┌────────────────────────┐ -│ MagicLick 2.5 │ ─────────────────────── │ xiaozhi-server │ -│ (xiaozhi-esp32 │ │ (stock xinnan-tech) │ -│ firmware 1.9.4) │ │ │ -└────────────────────┘ │ MCP client → │ - └───────────┬────────────┘ - │ JSON-RPC over HTTP - ▼ - ┌────────────────────────┐ - │ agentkeys-mcp-server │ - │ --backend http │ - └─────┬────────┬─────────┘ - │ │ - ▼ ▼ - ┌──────────────┐ ┌──────────────┐ - │ broker │ │ memory │ - │ + audit │ │ + cred │ - │ worker │ │ worker │ - └──────────────┘ └──────────────┘ - │ - ▼ - ┌──────────────────┐ - │ Heima parachain │ - │ (chain anchor) │ - └──────────────────┘ +┌──────────────────────┐ audio / ws ┌─────────────────────────┐ +│ any xiaozhi device │ ─────────────────────── │ xiaozhi cloud (LLM, │ +│ already in the wild │ │ STT, TTS, intent) │ +└──────────────────────┘ │ │ + │ 智控台 + mcp_endpoint │ + │ config: ws://relay/... │ + └────────────┬────────────┘ + │ ws + ▼ + ┌───────────────────────────┐ + │ mcp-endpoint-server │ + │ (relay; one Python proc, │ + │ github.com/xinnan-tech/ │ + │ mcp-endpoint-server) │ + └─────┬────────────┬────────┘ + │ tool path │ client path + │ │ + ▼ ▼ + ┌──────────────────────────────────────────┐ + │ agentkeys-mcp-server │ + │ --transport mcp-endpoint │ + │ --mcp-endpoint ws://relay/.../?token=… │ + └─────┬────────────────┬───────────────────┘ + │ │ + ▼ ▼ + ┌──────────────┐ ┌──────────────┐ + │ broker │ │ memory │ + │ + audit │ │ + cred │ + │ worker │ │ worker │ + └──────────────┘ └──────────────┘ + │ + ▼ + ┌──────────────────┐ + │ Heima parachain │ + └──────────────────┘ ``` -### B.2 Prerequisites (fresh laptop → demo, no shortcuts) +What this path eliminates from the original draft: -1. **AWS access** — `agentkeys-admin` profile, per [`docs/cloud-setup.md`](../../cloud-setup.md).

The honest fix: don't require an email at all on first run. Match the existing setup-broker-host.sh pattern. The script now tries three behaviors in order: 1. Existing ACME account on host (most common — setup-broker-host.sh registers one when it issues broker.litentry.org). Reuse silently, no email flag needed. 2. --certbot-email explicitly passed. Used as the account email for a new ACME registration. 3. Fall through to --register-unsafely-without-email. Cert still issues. Operator can re-run later with --certbot-email to attach a recovery address. Runbook B.5 updated to drop the fabricated email + explain the three behaviors. Suggests team aliases like agentkeys@litentry.org or infra@litentry.org IF Litentry has those, with the honest note that this script does not know which addresses are real. --- docs/spec/plans/issue-107-mcp-demo-runbook.md | 13 ++++++------ scripts/setup-mcp-host.sh | 21 ++++++++++++++++--- 2 files changed, 24 insertions(+), 10 deletions(-) diff --git a/docs/spec/plans/issue-107-mcp-demo-runbook.md b/docs/spec/plans/issue-107-mcp-demo-runbook.md index c288e2f..037c12b 100644 --- a/docs/spec/plans/issue-107-mcp-demo-runbook.md +++ b/docs/spec/plans/issue-107-mcp-demo-runbook.md @@ -423,16 +423,15 @@ The whole §B.5–§B.6 install (mcp-endpoint-server clone + venv, agentkeys-mcp Run it on the broker host (same host setup-broker-host.sh ran on): ```bash -# First-time run — needs an email for the certbot cert issuance. -bash scripts/setup-mcp-host.sh \ - --domain mcp.litentry.org \ - --certbot-email ops@litentry.org - -# Subsequent re-runs — same command, cert is reused, only drifted files are -# rewritten.

Add a "0/9 distro packages" step that idempotently apt-installs python3-venv + python3-pip + git (+ nginx + certbot when those layers are enabled). dpkg -s per package so the script's ok/skip/fail output stays honest. dnf branch for RHEL-family hosts. Mirrors setup-broker-host.sh's pattern. 2. Treat .venv as "healthy" only when .venv/bin/python3 exists AND runs `pass` successfully. If a prior run failed mid-create (typical when python3-venv was missing), the .venv directory exists but is broken; the new logic detects this, removes it, and recreates. Without the fix, the script's "already exists" skip would lock the host in the broken state across re-runs. Reproduces the user's reported error: 'The virtual environment was not created successfully because ensurepip is not available. On Debian/Ubuntu systems, you need to install the python3-venv package...'

Root causes: 1. `http2 on;` directive only lands in nginx 1.25.1+ (July 2023). The broker host's nginx is older (1.18 / 1.22 era). Old syntax `listen 443 ssl http2;` works on both — switched to that. 2. The vhost referenced /etc/letsencrypt/live//fullchain.pem before the cert existed → certbot's `nginx -t` preflight failed → certbot refused to issue → chicken-and-egg. Fix: two-phase nginx config (same pattern setup-broker-host.sh uses): Phase A (cert missing): :80-only vhost with ACME challenge location at /.well-known/acme-challenge/ and a 503 default. nginx loads cleanly with no cert paths. Phase B (cert present): full :80 → :443 redirect + TLS-terminating :443 ssl http2 vhost with the wss → ws upgrade proxy. Cert paths are now valid. Single-run flow takes the host from zero → cert → phase B without operator intervention: 1. Step 7 writes phase A and reloads nginx mid-step (so the ACME http-01 challenge has a live listener to talk to). 2. Step 8 switches certbot from `--nginx` plugin to webroot mode (`certbot certonly --webroot -w /var/www/html`) — issues the cert without trying to mutate the vhost we just wrote. 3. Step 8 then rewrites the vhost to phase B inline. 4. Step 9 reloads nginx with phase B → TLS is live. Re-runs after the cert is issued skip steps 8's issuance entirely (idempotency check stays — `test -f /etc/letsencrypt/live/.../fullchain.pem`). Also: pre-create /var/www/html so certbot --webroot doesn't fail on missing dir. --- scripts/setup-mcp-host.sh | 145 ++++++++++++++++++++++++++++++++------ 1 file changed, 123 insertions(+), 22 deletions(-) diff --git a/scripts/setup-mcp-host.sh b/scripts/setup-mcp-host.sh index fdcf860..7d60f15 100755 --- a/scripts/setup-mcp-host.sh +++ b/scripts/setup-mcp-host.sh @@ -353,10 +353,25 @@ fi # ─── 7. nginx vhost (TLS-terminating wss → ws) ─────────────────────── if [ "$WITH_NGINX" = "yes" ]; then head "7/9 nginx vhost (TLS-terminating wss → ws for ${DOMAIN})" - want_vhost=$(cat </dev/null || true) if [ "$want_vhost" = "$got" ]; then - skip "${NGINX_SITE##*/} already up to date" + skip "${NGINX_SITE##*/} (phase $NGINX_PHASE) already up to date" else printf '%s\n' "$want_vhost" | sudo tee "$NGINX_SITE" >/dev/null - ok "wrote ${NGINX_SITE##*/}" + ok "wrote ${NGINX_SITE##*/} (phase $NGINX_PHASE)" RELOAD_NGINX=1 fi if [ -L "$NGINX_SITE_LINK" ] || [ -e "$NGINX_SITE_LINK" ]; then @@ -427,6 +457,16 @@ EOF ok "enabled site ${NGINX_SITE_LINK##*/}" RELOAD_NGINX=1 fi + + # Reload nginx NOW (mid-step) so certbot's webroot challenge can + # land against the live phase-A vhost.

DNS check in step 8 — `dig | head -1` called the function with arg "-1", printing `==> -1` to stderr and producing empty DNS_IP. Symptom: spurious `==> -1` lines + script always reports DNS missing. 2. gen_token() in step 2 — `head -c 32 /dev/urandom | base64 | …` produced empty tokens for every run since the script was written. Existing /etc/agentkeys/mcp-tool-token + mcp-health-key on the broker host are very likely empty 0-byte files; this fix's next run will detect that (sudo test -s fails on 0 bytes), regenerate with real 32-char tokens, and the wss:// + health URLs become valid. Fixes use `command head` to bypass the function, leaving the head() section-header style intact for the rest of the script. Also dropped the 3-minute DNS poll loop per operator preference — now a single-shot check: DNS resolves → run certbot; DNS missing → skip with clear pointer to `setup-cloud.sh --only-step 6`. --- scripts/setup-mcp-host.sh | 25 ++++++++++--------------- 1 file changed, 10 insertions(+), 15 deletions(-) diff --git a/scripts/setup-mcp-host.sh b/scripts/setup-mcp-host.sh index cee711b..e535314 100755 --- a/scripts/setup-mcp-host.sh +++ b/scripts/setup-mcp-host.sh @@ -163,7 +163,7 @@ fi # ─── 2.

Fix: the health check now imports the relay's actual key deps — uvicorn, fastapi, websockets, loguru. If any fail to import, the venv is rebuilt from scratch.

RUNTIME PANIC on first wss:// connect: thread 'main' panicked: Could not automatically determine the process-level CryptoProvider from Rustls crate features. tokio-tungstenite 0.23 pulls rustls in with `default-features = false` and no provider feature, so rustls 0.23 refuses to auto-select. Fix: add `rustls = { …, features = ["ring"] }` as a direct dep and call `rustls::crypto::ring::default_provider().install_default()` at the top of main(). 2. RELAY CLOSED CONNECTION 30ms after we connect: We were advertising protocolVersion "2025-03-26" but xiaozhi's hosted relay speaks "2024-11-05". MCP says servers should negotiate the lower version. We weren't, so xiaozhi closed the WS as an unsupported-version signal. Fix: handle_initialize now echoes the client's protocolVersion when it's a known version.

So it bailed out and returned no response. Two-part fix: 1. Identity is now ambient instead of per-call. - New Config fields default_actor / default_operator_omni / default_device_key_hash, populated from CLI flags or env vars (MCP_DEFAULT_*). Auto-seeded to DEMO_* constants in --backend=in-memory mode. - memory.get/put, cap.mint, permission.check all fall back to the config defaults when the LLM omits these params. LLM still allowed to pass them, but never required to. 2. Tool descriptions + schemas rewritten for LLM consumption. - Descriptions are now natural-language usage cues: "Use this when the user references their past: 'where did I go', 'what do I like'". Memory namespaces have an enum with hints for each topic. - `required` now only lists LLM-callable params: `namespace`, `content`, `scope`, `op`. Engineer-only fields (actor, operator_omni, device_key_hash) moved out of required. Verified live against wss://api.xiaozhi.me/mcp/?token=… — the new tools/list payload now ships the readable descriptions and minimal required set.

Descriptions use imperatives ("ALWAYS use this tool…") not soft cues 2. Names + params are NOT abbreviated and the docstring guides WHEN to use 3. tools/list payload stays small (token budget enforced upstream) Changes: - Strengthened memory.get/put + permission.check descriptions to "ALWAYS use this tool to …" with both EN and 中文 trigger phrases (e.g. "我这周末去哪里玩", "记住", "我对什么过敏", "下单", "点 X 块的"…). The xiaozhi cloud is Chinese-tuned; English-only descriptions don't trigger reliably for zh queries. - Dropped the enum constraint on `namespace` — let the LLM pass any value, handler / backend accepts. The enum was over-restrictive. - Dropped the 3 M4 schema-only stubs (delegation.grant, delegation.revoke, approval.request) from `all_descriptors()`. They remain dispatchable via tools/call (returning not_implemented_in_v1 per #107 spec) but no longer eat tool-list budget. Re-add when M4 ships. Updated http_auth test from `tools.len() == 10` to `tools.len() == 7` + asserts the 3 stubs are NOT in tools/list. Payload size: 4554 → 4188 bytes. 31 tests still pass. --- crates/agentkeys-mcp-server/src/tools/mod.rs | 89 ++++++++----------- .../agentkeys-mcp-server/tests/http_auth.rs | 16 +++- 2 files changed, 52 insertions(+), 53 deletions(-) diff --git a/crates/agentkeys-mcp-server/src/tools/mod.rs b/crates/agentkeys-mcp-server/src/tools/mod.rs index f94f8a3..c83ecf0 100644 --- a/crates/agentkeys-mcp-server/src/tools/mod.rs +++ b/crates/agentkeys-mcp-server/src/tools/mod.rs @@ -31,27 +31,39 @@ pub fn all_descriptors() -> Vec { // resolved server-side from MCP_DEFAULT_* env vars (auto-set to the // demo fixture in --backend=in-memory mode).

The previous commit dropped the stubs from tools/list while keeping them dispatchable via tools/call — so the smoke scripts need to follow suit. Updates: - mode-b-protocol.sh: EXPECTED_TOOLS now has the 7 active tools; added M4_STUB_TOOLS set + assertion that they're NOT in tools/list. - mode-d-xiaozhi-endpoint.sh: same change. Print line updated to "tools/list → 7 active tools through the relay (0 M4 stubs)". - mode-a + mode-c unchanged — both already use tools/call on the stubs (still dispatchable, still returns not_implemented_in_v1).

Tracing logged to stdout, corrupting the JSON-RPC wire. Claude Code / Desktop reserve stdout for JSON-RPC frames only. The tracing-subscriber default writes to stdout, so `INFO …` lines interleaved with responses → parse errors → disconnect. Fix: `.with_writer(std::io::stderr)` in main.rs. 2. Notifications got error responses. `notifications/initialized` has no `id` field. dispatch() routes it to the `_other` arm and returns method-not-found. The stdio writer then sent that response back, surprising the MCP client. Fix: check `req.id.is_none()` BEFORE writing the response — same pattern as the mcp-endpoint transport at transport.rs:198.

Per follow-up question, the actual functional E2E gap was that **stdio** — the path Claude Code / Codex CLI / Claude Desktop / Cursor / Cline / Roo / Windsurf / Gemini CLI all use — had zero coverage: mode-a HTTP via curl ← existed mode-b HTTP via Anthropic mcp SDK ← existed mode-c HTTP via xiaozhi client ← existed mode-d WS via mcp-endpoint relay ← existed mode-e stdio via stdio_client ← NEW scripts/mcp-demo-mode-e-stdio.sh Full three-act storyboard against an installed binary, driven through Anthropic's Python `mcp` SDK stdio_client (same code path Claude Code uses internally). 12 assertions: • initialize handshake, server name+version • tools/list → 7 active tools, all expected • memory.get(travel) returns Chengdu fixture • memory.get(family) returns family fixture • memory.put + memory.get round-trip with Chinese unicode (有痛风) • permission.check denies 600 RMB with storyboard wording (cap=500) • permission.check accepts 100 RMB • cap.mint returns valid nonce • cap.revoke(known) ok, cap.revoke(unknown) rejected • audit.append returns envelope_hash with 0x prefix • identity.whoami resolves ambient default actor Auto-detects binary at $1 → $AGENTKEYS_MCP_BIN → standard install paths. Bootstraps uv + venv + mcp SDK on first run, reuses thereafter. The script EXPOSED a real bug: identity.whoami still demanded `actor` despite the schema being optional. Tools/mod.rs had been LLM-friendly- ified (mostly) but the handler wasn't. Fixed: identity::call now reads config.default_actor as fallback, mirroring memory.get/put + cap.mint + permission.check. Added 2 unit tests for the fallback path. This is exactly the class of bug install-only smoke misses. Workflow updates: • mcp-server.yml: cargo build --release + mode-e added to existing ladder; paths trigger updated; uv install comment now says B/C/D/E • release.yml: inline 3-line python smoke replaced with mode-e call against the freshly-installed-from-tarball binary (the actual gate) • cargo-install-smoke.yml: same upgrade for the `cargo install --git` canary; weekly Monday run now exercises full storyboard Verified locally: cargo test 31/31 pass; mode-e 12/12 pass against ~/.local/bin/agentkeys-mcp-server reinstalled with the identity fix. --- .github/workflows/cargo-install-smoke.yml | 37 ++-- .github/workflows/mcp-server.yml | 21 +- .github/workflows/release.yml | 46 ++--- crates/agentkeys-mcp-server/src/server.rs | 2 +- .../src/tools/identity.rs | 38 +++- scripts/mcp-demo-mode-e-stdio.sh | 180 ++++++++++++++++++ 6 files changed, 255 insertions(+), 69 deletions(-) create mode 100755 scripts/mcp-demo-mode-e-stdio.sh diff --git a/.github/workflows/cargo-install-smoke.yml b/.github/workflows/cargo-install-smoke.yml index ce70ef4..87bcb91 100644 --- a/.github/workflows/cargo-install-smoke.yml +++ b/.github/workflows/cargo-install-smoke.yml @@ -47,33 +47,18 @@ jobs: ls -la "$HOME/.cargo/bin/agentkeys-mcp-server" agentkeys-mcp-server --help 2>&1 | head -10 || true - - name: stdio handshake smoke test + - name: install uv (for mode-e functional E2E) + run: curl -LsSf https://astral.sh/uv/install.sh | sh + + - name: functional E2E — three-act storyboard over stdio (mode E) + # Same gate as release.yml: full three-act storyboard via Anthropic's + # mcp Python SDK stdio_client against the binary `cargo install` + # just placed in ~/.cargo/bin.

fold MCP into setup-cloud.sh MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per #132 PR review directives — drop the over-eager release pipeline, let cargo install --git be the canonical install for now (until M6 ships GH Releases + agentkeys CLI, tracked as #134), fold MCP-on-broker bring-up into setup-cloud.sh as a proper step. Drops (deferred to M6 / #134): - .github/workflows/release.yml - .github/workflows/cargo-install-smoke.yml - scripts/install-mcp-server.sh Mode-e functional E2E stays in mcp-server.yml (the only CI place where functional checks run now, per directive). That alone catches the regression class release.yml would have caught. setup-mcp-host.sh step 4 — replaced local `cargo build --release` + binary copy with `cargo install --git $REPO_URL --branch $REV`. Removes the implicit "you must have the repo cloned at REPO_ROOT" requirement; broker host no longer needs the source tree. AGENTKEYS_REPO_URL + AGENTKEYS_REV env vars let devs point at a fork / PR branch. systemd unit's WorkingDirectory shifted from $REPO_ROOT → $ENV_FILE_DIR (/etc/agentkeys) since the source tree is no longer required at runtime. setup-cloud.sh — new step 15 ("Bring up agentkeys-mcp-server on broker via SSM"). Uses aws ssm send-command to: 1. Ensure cargo is installed on broker (rustup minimal if missing) 2. Clone or fetch the repo at /opt/agentkeys-src 3. Run scripts/setup-mcp-host.sh (which uses cargo install --git) Test variant (--test flag) passes --test through to setup-mcp-host.sh, which already knew about it from #132. Polls SSM command for up to 10 min, tails stdout/stderr on completion. Surgical re-runs supported via --only-step 15 + --only-step 15 --test for the two variants. STEP_TOTAL bumped 15 → 16; old summary moved to do_step_16. Runbook §B.5 — leads with `bash scripts/setup-cloud.sh --only-step 15` for prod/test deploy + `cargo install --git ...` for local dev install (Claude Code / Codex / Claude Desktop), with the LLM-host wiring snippets inline. Mode A (xiaozhi-hosted) / Mode B (self-hosted) still documented as setup-mcp-host.sh modes when running on broker directly. Drops the stale "cargo build --release locally" reference in the deliverables list. Verified locally: cargo test 31/31 pass, bash -n clean on both scripts. --- .github/workflows/cargo-install-smoke.yml | 67 ------ .github/workflows/release.yml | 202 ------------------ docs/spec/plans/issue-107-mcp-demo-runbook.md | 64 ++++-- scripts/install-mcp-server.sh | 130 ----------- scripts/setup-cloud.sh | 98 ++++++++- scripts/setup-mcp-host.sh | 50 +++-- 6 files changed, 179 insertions(+), 432 deletions(-) delete mode 100644 .github/workflows/cargo-install-smoke.yml delete mode 100644 .github/workflows/release.yml delete mode 100755 scripts/install-mcp-server.sh diff --git a/.github/workflows/cargo-install-smoke.yml b/.github/workflows/cargo-install-smoke.yml deleted file mode 100644 index 87bcb91..0000000 --- a/.github/workflows/cargo-install-smoke.yml +++ /dev/null @@ -1,67 +0,0 @@ -name: cargo-install-smoke - -# Canary for the `cargo install --git` distribution path. -# -# Why: Option B in #107 — Rust devs can `cargo install --git -# https://github.com/litentry/agentKeys agentkeys-mcp-server` to get -# the binary without an OS-specific release.

Issue #107 added agentkeys-mcp-server as a separate top-level Rust binary crate, but arch.md only listed the legacy agentkeys-mcp (in-process adapter library used by the daemon's sidecar loop). Cargo workspace had both crates; arch.md had only one. Updates to docs/arch.md §23 (crate tree + table): - Tree: agentkeys-mcp-server entry added below agentkeys-mcp, with one- line description of its role + transports - Table: agentkeys-mcp row clarified as "legacy in-process adapter library — used by daemon's sidecar stdio loop (M0)"; new row for agentkeys-mcp-server documents the three transports (stdio / HTTP / xiaozhi mcp-endpoint WS), two backends (in-memory / http), and the canonical install command per #134 No language contradictions found elsewhere in arch.md (grep for MCP×python|node|typescript returned 0 matches).
