The current work queue is focused on P3–P6 (core/tray separation + API + embedded UI). +- **Module integrity rule**: Treat each component as a testable boundary the team can lock.

Append `--show-report` if you want the HTML report server for manual inspection.

The immediate priority is a stable core `mcpproxy` daemon (REST/SSE + embedded web UI) with a separate tray binary that talks to it over the new HTTP API. Alongside architecture and quality goals, every component should present a testable module boundary so we can lock behaviour for future LLM-driven edits. The items below focus on stabilising that architecture before chasing later phases. + +## 1. Carve Out a Core Runtime Layer (High Impact, Near-Term) +- **Why**: `internal/server/server.go` combines lifecycle management, HTTP wiring, MCP tool routing, storage/index orchestration, and tray-facing status fan-out in a single 1.4k LOC type. This makes it hard to evolve the REST API and tray separately. +- **Action**: Extract a `runtime` (or `app/core`) package that owns config loading, storage/index lifecycle, upstream manager wiring, and status events. Keep HTTP concerns (`internal/httpapi`, SSE fan-out, static web) in thin adapters that depend on the runtime via interfaces. +- **Outcome**: Core logic becomes testable without HTTP, alternative interfaces (CLI helpers, future gRPC) can reuse the runtime, and the tray binary interacts with a narrow contract. + +- **Why**: REST handlers (`internal/httpapi/server.go`) and the tray client (`cmd/mcpproxy-tray/internal/api/client.go`) each define their own structs, mostly as `map[string]interface{}`. This duplication causes drift whenever we add fields or modify JSON formats. +- **Action**: Introduce a shared `pkg/contracts` (name TBD) with typed DTOs for server status, logs, tool metadata, and SSE payloads. The HTTP layer should marshal these types, and generated TypeScript definitions (via `go2ts`/`swag`) can feed the Vue UI and tray bindings. +- **Outcome**: One schema for all surfaces, easier validation, and clearer evolution path for `/api/v1`. + +## 3. Replace File-Watcher Feedback Loops with an Internal Event Bus +- **Why**: `Server.EnableServer`/`QuarantineServer` persist to Bolt, then rely on the tray's fsnotify watcher to rediscover changes (see `internal/server/server.go` ~lines 720-820). That introduces eventual consistency and duplicate logic in the tray managers. +- **Action**: Let the core runtime publish typed events (server added/enabled/quarantined, OAuth flow required) on an internal bus. The REST layer, SSE broadcaster, and tray bridge subscribe directly, eliminating the need for the tray to watch config files or poke at Bolt. +- **Outcome**: Immediate UI updates, fewer cross-process DB conflicts, and a cleaner path to future remote UIs. + +## 4. Retire Remaining `/api` Shims in Favour of `/api/v1` +- **Why**: We now expect every client (tray + web UI) to use the new REST surface introduced during this refactor. Keeping the older handler stack alive only increases maintenance cost. +- **Action**: Delete the duplicate mux wiring for `/api`, move any still-needed helper logic under the shared contracts package, and update the tray client to rely solely on `/api/v1` endpoints (done JanΒ 2025; legacy handlers removed). +- **Outcome**: Single REST surface to secure, document, and test (OpenAPI, golden tests in P11) with no legacy code paths lingering. + +## 5. Observation & Health Surface as Dedicated Modules +- **Why**: `REFACTORING.md` P10 calls for health/readiness, Prometheus, and traces. Today, status reporting is baked into `internal/server` and the SSE stream. +- **Action**: Introduce an `internal/observability` package that exposes health probes, metrics registration, and trace helpers. HTTP adapters simply mount the handlers. This keeps telemetry independent from the runtime refactor and avoids leaking prom/otel globals through business logic. +- **Outcome**: Cleaner layering now, easier to implement P10 without touching tray/web. + +## 6. Testing & Tooling Support for the Split +- **Why**: We currently rely on end-to-end tests in `internal/server` that spin up the whole stack. As we separate binaries, we need targeted coverage. +- **Action**: Add subpackage tests around the new runtime interfaces (mocking transport/storage), and introduce contract tests that exercise the REST API + tray client over HTTP using the shared DTOs. +- **Outcome**: Confidence that the core remains functional while the tray migrates, enabling quicker iterations on both binaries. + +## 7. Enforce Module Boundaries So Features Stay Locked +- **Why**: Large, monolithic packages make it easy for automated refactors to accidentally remove cross-cutting behaviour. Clear boundaries let us freeze mature areas while iterating on adjacent code. +- **Action**: Define explicit interfaces between runtime, HTTP adapters, storage/index, tray bindings, and UI. Guard each module with focused unit/contract tests and document the "public" surface so future LLM agents know what not to delete. +- **Outcome**: Safer concurrent workstreams and a path to lock high-value features through tests instead of conventions. + +## 8. Lean Into LLM Generate β†’ Verify Loops +- **Why**: Refactor velocity hinges on how quickly we can iterate with LLM help without regressing behaviour. +- **Action**: Standardise a loop where agents generate a change, then verify it with: + - `go test` / targeted module suites for backend pieces. + - `curl` recipes for `/api/v1` endpoints (healthy servers, enable/disable, tool search). + - Playwright CLI scenarios (`npx playwright test .playwright-mcp/web-smoke.spec.ts`) that drive the embedded web UI (status dashboard, tool search, server detail flows). +- **Outcome**: Faster feedback for both humans and LLM contributors, higher confidence before code review, and reusable scripts for CI gating. + +## 9. Pre-Boot MCP "Everything" Server for Repeatable CLI/E2E Runs +- **Why**: The MCP protocol E2Es invoke `npx @modelcontextprotocol/server-everything` for every scenario, introducing multi-minute hangs and occasional timeouts. +- **Action**: Build or download the everything server once per test session (e.g. `npm exec --yes --package @modelcontextprotocol/server-everything -- mcp-server --stdio`) and cache the executable/socket. Point the CLI wrapper and `scripts/run-e2e-tests.sh` to the warmed instance so individual tests reuse it instead of spawning `npx` repeatedly. +- **Outcome**: MCP suites finish inside CI time budgets, binary smoke tests regain reliability, and local developer loops remain fast while keeping coverage. + +## 10. Automate Playwright + Curl Verification Recipes +- **Why**: Contributors frequently skip manual API/UI validation, leaving regressions for later phases. +- **Action**: Check in scripted helpers alongside the new `.playwright-mcp/web-smoke.spec.ts` run: + - `scripts/verify-api.sh` to exercise the canonical `curl` calls (servers list, enable/disable, tool sync, status stream). + - `scripts/run-web-smoke.sh` wrapper that boots a local server and invokes `npx playwright test .playwright-mcp/web-smoke.spec.ts`, capturing HTML/console artifacts on failure (pass `--show-report` for an interactive HTML viewer). + - Document both scripts in `REFACTORING.md` Phase 1 so every handoff runs them by default. +- **Outcome**: API/UI verification becomes a single command, LLM agents follow a consistent workflow, and regressions surface before merges. + +--- + +These changes keep us focused on the core goalβ€”shipping a working core daemon + web UI plus a thinner tray appβ€”while laying scaffolding for the later resilience/security milestones in the refactor plan. diff --git a/MANUAL_TESTING.md b/MANUAL_TESTING.md new file mode 100644 index 00000000..d03d6cb3 --- /dev/null +++ b/MANUAL_TESTING.md @@ -0,0 +1,521 @@ +# MCPProxy Manual Testing Guide + +This guide provides step-by-step instructions for manually testing the refactored mcpproxy with all new features. + +## Prerequisites + +1. **Go 1.23+** installed +2. **Node.js** and **npm** for testing MCP servers +3. **jq** for JSON processing +4. **Docker** (optional, for testing Docker isolation) + +## Quick Start + +### 1.

Port Conflict Recovery (Tray) + +1. Hold the default port to simulate a conflict: + + ```bash + # Terminal A + python3 -m http.server 8080 + ``` + +2. Launch the tray build and allow it to start the core. The status menu displays **Port conflict** with a dedicated submenu. +3. Use **Resolve port conflict β†’ Use available port …** to switch the core to an automatically selected free port. The tray persists the new value in `mcp_config.json` and restarts the server. +4. Alternatively choose **Retry start** once you have released the original port or **Open config directory** to edit the listen address manually. +5. On macOS you can automate the interaction with the new submenu via `osascript`: + + ```applescript + osascript <<'EOF' + tell application "System Events" + tell process "mcpproxy-tray" + click menu bar item 1 of menu bar 1 + click menu item "Resolve port conflict" of menu 1 of menu bar item 1 of menu bar 1 + delay 0.2 + click menu item "Use available port" of menu 1 of menu item "Resolve port conflict" of menu bar item 1 of menu bar 1 + end tell + end tell + EOF + ``` + +6. Verify the new port by inspecting the tray tooltip (now shows the bound address) and by calling `curl http://localhost:/healthz`. + +### 7. Tray Environment Overrides + +1. Export custom overrides before launching the tray: + + ```bash + export MCPPROXY_TRAY_LISTEN=:9090 + export MCPPROXY_TRAY_CONFIG_PATH="$PWD/test-data/config.json" + ``` + +2. Start `mcpproxy-tray` and confirm the tooltip reports the `:9090` port while the logs show `--config` pointing to the chosen file. +3. Repeat with `MCPPROXY_TRAY_EXTRA_ARGS="--log-level debug"` to verify additional flags are forwarded. +4. Set `MCPPROXY_TRAY_SKIP_CORE=1`, start the tray while a separate `mcpproxy serve` is already running, and ensure the tray connects without spawning a new process. + +### 8.

The variables below let you attach the tray to a pre-launched core, skip automatic OAuth helpers, and keep instrumentation deterministic. + +## Quick Reference + +| Variable | Scope | Default | Purpose | +|----------|-------|---------|---------| +| `MCPPROXY_TRAY_SKIP_CORE` | Tray | unset | Prevents the tray from launching the core binary. | +| `MCPPROXY_CORE_URL` | Tray | `http://localhost:8080` | Overrides the core API endpoint the tray connects to. | +| `MCPPROXY_DISABLE_OAUTH` | Core | unset | Disables OAuth popups and tray-driven login prompts. | + +## Use Cases + +### Debugging the Core and Tray Separately + +When you want to attach two debuggers (one for the core binary, another for the tray) or restart the core without bouncing the tray: + +```bash +# terminal 1: start the core with verbose logging +MCPPROXY_DISABLE_OAUTH=true \ +go run ./cmd/mcpproxy serve --listen :8085 --tray=false --log-level=debug + +# terminal 2: build + run the tray without auto-spawning the core +MCPPROXY_TRAY_SKIP_CORE=1 \ +MCPPROXY_CORE_URL=http://localhost:8085 \ +go run ./cmd/mcpproxy-tray +``` + +**What happens** +- The tray icon appears immediately and connects to `:8085` once the core is ready. +- Because `MCPPROXY_TRAY_SKIP_CORE` is set, the tray never forks a new `mcpproxy` process. This lets you rebuild or restart the core freely. +- `MCPPROXY_DISABLE_OAUTH=true` ensures no OAuth browser windows are spawned during debugging. + +### VS Code Compound Debugging + +Add the following launch configurations to `.vscode/launch.json` (already included in the repo’s example setup): + +```jsonc +{ + "name": "Debug mcpproxy (.tree/next)", + "type": "go", + "request": "launch", + "mode": "exec", + "program": "${workspaceFolder}/.tree/next/mcpproxy", + "args": ["serve", "--listen", ":8085", "--tray", "false"], + "env": { + "CGO_ENABLED": "1", + "MCPPROXY_DISABLE_OAUTH": "true" + } +}, +{ + "name": "Debug mcpproxy-tray (.tree/next)", + "type": "go", + "request": "launch", + "mode": "exec", + "program": "${workspaceFolder}/.tree/next/mcpproxy-tray", + "env": { + "CGO_ENABLED": "1", + "MCPPROXY_TRAY_SKIP_CORE": "1", + "MCPPROXY_CORE_URL": "http://localhost:8085" + } +} +``` + +With a compound configuration that launches both entries, pressing F5 will: +1. Start the core under the debugger without tray UI. +2. Attach the tray to the already debugging core. + +### Automated UI Testing + +For Playwright, scripted tray checks, or MCP automation harnesses: + +```bash +# Start the core in headless mode +MCPPROXY_DISABLE_OAUTH=true \ +MCPPROXY_CORE_URL=http://localhost:18080 \ +mcpproxy serve --listen :18080 --tray=false & + +# Launch the tray with instrumentation enabled +MCPPROXY_TRAY_SKIP_CORE=true \ +MCPPROXY_CORE_URL=http://localhost:18080 \ +MCPPROXY_TRAY_INSPECT_ADDR=127.0.0.1:8765 \ +go run -tags traydebug ./cmd/mcpproxy-tray +``` + +The `traydebug` build tag exposes an HTTP inspector (see `/state`, `/action`) so automated tests can query the tray menu without needing Accessibility permissions. + +## Tips & Troubleshooting + +- If the tray still spawns a core instance, confirm `MCPPROXY_TRAY_SKIP_CORE` is set to `1` or `true` in the tray process environment. +- The core URL must include the protocol (e.g. `http://`); otherwise the Go HTTP client rejects it. +- Combine `MCPPROXY_DISABLE_OAUTH` with test configs to avoid OAuth popups in CI or when running unit tests. +- When running against non-default ports, update your MCP clients (Cursor, VS Code, etc.) to use the same port. + +### Resolving Port Conflicts + +If another process already uses the configured listen port, the tray now surfaces a **Resolve port conflict** sub-menu directly beneath the status indicator. From there you can: + +- Retry the existing port once you have freed it. +- Automatically switch to the next available port (the tray persists the new value and restarts the core for you). +- Copy the MCP connection URL to the clipboard for quick use in clients. +- Jump straight to the configuration directory if you prefer manual edits. + +For scripted verification on macOS you can drive the new menu via `osascript`: + +```applescript +osascript <<'EOF' +tell application "System Events" + tell process "mcpproxy-tray" + click menu bar item 1 of menu bar 1 + click menu item "Resolve port conflict" of menu 1 of menu bar item 1 of menu bar 1 + delay 0.2 + click menu item "Use available port" of menu 1 of menu item "Resolve port conflict" of menu bar item 1 of menu bar 1 + end tell +end tell +EOF +``` + +Adjust the inner menu titles if you localise the app; the defaults above match the English build. + +### Launcher Configuration + +The tray launches `mcpproxy serve` when it detects that no core is running. You can steer that subprocess with the following environment variables before starting the tray: + +- `MCPPROXY_CORE_URL` – full base URL the tray should connect to (e.g. `http://localhost:8085`). This also controls the health checks. +- `MCPPROXY_TRAY_LISTEN` / `MCPPROXY_TRAY_PORT` – override the port passed to `--listen` when the tray launches the core (formats accepted: `:8085` or `8085`). +- `MCPPROXY_TRAY_CONFIG_PATH` – absolute path to the `mcp_config.json` the tray should hand to the core via `--config`. +- `MCPPROXY_TRAY_EXTRA_ARGS` – optional additional CLI arguments (whitespace separated) appended after `serve`. +- `MCPPROXY_TRAY_SKIP_CORE` – set to `1` to prevent the tray from launching the core automatically (useful when attaching to an external instance). + +The tray’s status tooltip reflects the active listen address; when you change any of the variables above, restart the tray so it relaunches the core with the new settings. + +### Building a DMG with Both Binaries + +Use the updated packaging script to bundle the tray and core into a single notarizable DMG: + +```bash +GOOS=darwin GOARCH=arm64 go build -o dist/mcpproxy-tray ./cmd/mcpproxy-tray +GOOS=darwin GOARCH=arm64 go build -o dist/mcpproxy ./cmd/mcpproxy +./scripts/create-dmg.sh dist/mcpproxy-tray dist/mcpproxy v1.0.0 arm64 +``` + +The resulting `mcpproxy.app` contains: + +- `Contents/MacOS/mcpproxy` – the tray executable. +- `Contents/Resources/bin/mcpproxy` – the CLI core binary that the tray stages at runtime. + +When the DMG is mounted the user only needs to drag the app bundle to `/Applications`; the tray will manage the core automatically from that embedded location. + +## Further Reading + +- [docs/setup.md](./setup.md) – full installation and configuration walkthrough. +- [MANUAL_TESTING.md](../MANUAL_TESTING.md) – manual smoke scenarios that benefit from the environment flags above. +- [Playwright MCP server README](../.playwright-mcp/README.md) –

Server List Display +- **Expected:** List of configured servers (should show "everything" server) +- **Verify:** + - Server name, protocol, and status are displayed + - Connection status shows "Ready" for everything server + - Enabled/disabled state is correct + +#### 2. Real-time Updates (SSE) +- **Test:** Enable/disable a server via API while UI is open + ```bash + curl -X POST http://localhost:8081/api/v1/servers/everything/disable + curl -X POST http://localhost:8081/api/v1/servers/everything/enable + ``` +- **Expected:** UI updates automatically without page refresh +- **Verify:** Status changes reflect immediately in the UI + +#### 3. Tool Search Functionality +- **Test:** Search for tools using the search interface +- **Try searches:** "echo", "tool", "random", etc. +- **Expected:** Results appear with tool names, descriptions, and server info +- **Verify:** Search is responsive and results are relevant + +#### 4. Server Management +- **Test:** Enable/disable servers through the UI +- **Expected:** + - Controls are responsive + - Status updates immediately + - No page refreshes required + +#### 5. Tool Details +- **Test:** View tool details and descriptions +- **Expected:** + - Tool information is complete and formatted correctly + - Server attribution is clear + +#### 6. Logs Viewing (if implemented) +- **Test:** View server logs through the UI +- **Expected:** + - Logs are readable and properly formatted + - Recent logs appear first + - Auto-refresh if implemented + +#### 7. Error Handling +- **Test:** Trigger error conditions + - Stop mcpproxy server while UI is open + - Request invalid server operations +- **Expected:** + - Graceful error handling + - User-friendly error messages + - Proper reconnection when server returns + +## Browser Compatibility Testing + +Test the UI in multiple browsers: +- **Chrome/Chromium** (primary target) +- **Firefox** +- **Safari** (macOS) +- **Edge** (Windows) + +### Key areas to verify: +- SSE event handling +- JSON parsing +- CSS styling consistency +- JavaScript functionality + +## Performance Testing + +### Load Testing +1. **Multiple browser tabs:** Open UI in several tabs, verify all receive updates +2. **Rapid API calls:** Make quick successive API calls, verify UI stays responsive +3. **Long-running session:** Keep UI open for extended periods, verify memory usage + +### Network Testing +1. **Slow connections:** Test with throttled network +2. **Connection interruption:** Disconnect and reconnect network +3. **Server restarts:** Restart mcpproxy, verify UI reconnects properly + +## Accessibility Testing + +### Basic Accessibility +- **Keyboard navigation:** Ensure all interactive elements are keyboard accessible +- **Screen reader compatibility:** Test with screen reader software +- **Color contrast:** Verify sufficient contrast for visually impaired users +- **Alt text:** Check that images have appropriate alt text + +## Optional: Playwright MCP Server Testing + +**Note:** This is for ad-hoc testing and debugging only, not part of the automated test suite. + +If you have access to a Playwright MCP server, you can use it for more advanced UI automation: + +### Setup Playwright MCP Server +```json +{ + "mcpServers": { + "playwright": { + "command": "npx", + "args": ["-y",

+await playwright.waitForSelector("[data-testid='server-list']"); +await playwright.click("[data-testid='enable-everything-server']"); +``` + +## Common Issues and Debugging + +### UI Not Loading +1. **Check mcpproxy is running:** `curl http://localhost:8081/api/v1/servers` +2. **Verify UI is embedded:** Look for UI files in the binary +3. **Check browser console:** Look for JavaScript errors +4. **Network tab:** Verify API calls are succeeding + +### SSE Not Working +1. **Browser support:** Ensure browser supports Server-Sent Events +2. **Network blocking:** Check if corporate firewalls block SSE +3. **Console errors:** Look for SSE connection errors in browser console + +### API Errors +1. **CORS issues:** Check Access-Control headers in network tab +2. **Authentication:** Verify no unexpected auth requirements +3. **Server logs:** Check mcpproxy logs for API errors + +## Automated UI Testing (Future) + +While the core test suite doesn't include automated UI tests, here's how they could be implemented: + +### Potential Tools +- **Playwright:** For full browser automation +- **Selenium:** Cross-browser testing +- **Cypress:** Modern e2e testing framework + +### Test
