# Phase 03-01: MCP Server Implementation - Summary

## Completed Tasks

### Task 1: Dependencies and Entry Points
- Added `fastmcp>=2.14.4` to project dependencies
- Added `corpus` entry point alias to `[project.scripts]`
- Added `"src/corpus"` to `[tool.hatch.build.targets.wheel]` packages
- Verified `uv run corpus --help` executes successfully

### Task 2: FastMCP Server Module
- Created `src/corpus_analyzer/mcp/__init__.py` with package docstring
- Created `src/corpus_analyzer/mcp/server.py` with:
  - `logging.basicConfig(stream=sys.stderr)` as first import-time statement (MCP-04)
  - `corpus_lifespan` for pre-warming embeddings and initializing `CorpusSearch` (MCP-06)
  - `FastMCP("corpus", lifespan=corpus_lifespan)` instance
  - `corpus_search` tool with `Optional[str]` parameters (MCP-05 schema compatibility)
  - No `print()` statements anywhere in the file (MCP-04)

## Verification Results

All checks passed:
- `uv run corpus --help` exits 0
- `from corpus_analyzer.mcp.server import mcp` imports cleanly
- `mypy src/corpus_analyzer/mcp/` passes with no strict errors
- `ruff check src/corpus_analyzer/mcp/` passes with no lint errors
- `grep -n "print(" src/corpus_analyzer/mcp/server.py` returns nothing

## Success Criteria Met

- `pyproject.toml` has `fastmcp>=2.14.4` in dependencies
- `corpus` entry point alias is registered
- `src/corpus` is in the wheel packages list
- FastMCP server module is importable
- Server has lifespan pre-warm functionality
- Single `corpus_search` tool implemented
- Tool uses `Optional[str]` for all optional params (not `str | None`)
- `logging.basicConfig(stream=sys.stderr)` is the first import-time statement
- No `print()` anywhere in `mcp/server.py`

## Next Steps

Phase 03-01 is complete. Proceed to Phase 03-02 as defined in the roadmap.
