notes-mcp

Remote MCP server exposing a personal notes git repo to Claude via the mobile/web app. Notes are markdown files (or folders with index.md, data files, and runnable scripts); every write is a prettier-formatted git commit pushed to GitHub. Auth is OAuth 2.1 served by this server with GitHub as the login identity, fronted by a Cloudflare Tunnel.

Development

uv sync                                  # deps (Python 3.14, uv-managed)
uv run pytest
uv run ruff check src tests && uv run ruff format --check src tests
uv run ty check

# run locally against any notes working tree (git optional; push needs origin)
NOTES_REPO_PATH=~/notes MCP_PORT=8000 uv run notes-mcp

Requires git and rg (ripgrep) on PATH; prettier optional locally (writes commit unformatted without it). The MCP endpoint is http://host:port/mcp (streamable HTTP); GET /health is a public liveness probe. CI (.github/workflows/ci.yml) runs ruff, ty, and pytest.

One-time after cloning: git config core.hooksPath .githooks — enables the pre-commit hook that prettier-formats staged markdown.

Local-dev degraded modes (production uses the full path):

• NOTES_REPO_PATH not a git repo → filesystem only, no commits

• git repo without an origin remote → commits locally, skips pull/push

• PUBLIC_URL unset → auth disabled (logged warning)

Container

docker build -t notes-mcp:<ver> .
docker save notes-mcp:<ver> | gzip > notes-mcp-<ver>.tar.gz

Then follow deploy/README.md — in short: sh deploy/deploy.sh <env-file> <tarball> runs the server plus a cloudflared sidecar sharing its network namespace. docker-compose.yml encodes the same shape declaratively if you prefer compose.
