+# CLAUDE.md
+
+This file provides guidance to Claude Code when working with code in this repository.
+
+## Project Overview
+
+Official MCP reference server implementations. This is an npm workspaces monorepo containing 7 servers (4 TypeScript, 3 Python) under `src/`. Each server is a standalone package published to npm or PyPI.
+
+## Monorepo Structure
+
+```
+src/
+  everything/          TS  @modelcontextprotocol/server-everything    (reference server, all MCP features)
+  filesystem/          TS  @modelcontextprotocol/server-filesystem    (file operations with Roots access control)
+  memory/              TS  @modelcontextprotocol/server-memory        (knowledge graph persistence)
+  sequentialthinking/  TS  @modelcontextprotocol/server-sequential-thinking  (step-by-step reasoning)
+  fetch/               Py  mcp-server-fetch                           (web content fetching)
+  git/                 Py  mcp-server-git                             (git repository operations)
+  time/                Py  mcp-server-time                            (timezone queries and conversion)
+```
+
+## Build & Test Commands
+
+### TypeScript servers
+
+```bash
+# Single server
+cd src/<server> && npm ci && npm run build && npm test
+
+# All TS servers from root
+npm install && npm run build
+```
+
+- Build: `tsc` (target ES2022, module Node16, strict mode)
+- Tests: **vitest** with `@vitest/coverage-v8` (required for new tests)
+- Node version: **22**
+
+### Python servers
+
+```bash
+cd src/<server> && uv sync --frozen --all-extras --dev
+
+# Run tests (if tests/ or test/ directory exists)
+uv run pytest
+
+# Type checking
+uv run pyright
+
+# Linting
+uv run ruff check .
+```
+
+- Build system: **hatchling** (`uv build`)
+- Package manager: **uv** (not pip)
+- Python version: **>= 3.10** (per-server `.python-version` file)
+- Type checking: **pyright** (enforced in CI)
+- Linting: **ruff**
+
+## Code Style
+
+### TypeScript
+
+- ES modules with `.js` extension in import paths
+- Strict TypeScript typing for all functions and variables
+- Zod schemas for tool input validation
+- 2-space indentation, trailing commas in multi-line objects
+- camelCase for variables/functions, PascalCase for types/classes, UPPER_CASE for constants
+- kebab-case for file names and registered tools/prompts/resources
+- Verb-first tool names (e.g., `get-file-info`, not `file-info`)
+- Imports grouped: external first, then internal
+
+### Python
+
+- Type hints enforced via pyright
+- Async/await patterns (especially in fetch server with pytest-asyncio)
+- Follow existing module layout per server
+
+## Contributing Guidelines
+
+**Accepted:** Bug fixes, usability improvements, enhancements demonstrating MCP protocol features (Resources, Prompts, Roots -- not just Tools).
+
+**Selective:** New features outside a server's core purpose or highly opinionated additions.
+
+**Not accepted:** New server implementations (use the [MCP Server Registry](https://github.com/modelcontextprotocol/registry)), README server listing changes.
+
+## CI/CD Pipeline
+
+Both TypeScript and Python workflows use **dynamic package detection** (find + jq matrix strategy):
+
+1. `detect-packages` -- finds all `package.json` / `pyproject.toml` under `src/`
+2. `test` -- runs tests per package
+3. `build` -- compiles and type-checks per package
+4. `publish` -- on release events only (npm for TS, PyPI trusted publishing for Python)
+
+## MCP Protocol Reference
+
+The repo is configured with an MCP docs server (`.mcp.json`) pointing to `https://modelcontextprotocol.io/mcp`. For schema details, reference `https://github.com/modelcontextprotocol/modelcontextprotocol/tree/main/schema` which contains versioned schemas in JSON and TypeScript formats.
+
+## Key Patterns
+
+- Each server registers capabilities via `registerTools(server)`, `registerResources(server)`, `registerPrompts(server)` functions
+- Tool annotations: set `readOnlyHint`, `idempotentHint`, `destructiveHint` per MCP spec
+- Transport support: stdio (default), SSE (deprecated), Streamable HTTP
+- All PRs are reviewed against the [PR template](.github/pull_request_template.md) checklist -- ensure MCP docs are read, security best practices followed, and changes tested with an LLM client
