It turns curated GraphQL operation files into [FastMCP](https://gofastmcp.com/) tools backed by a GraphQL **supergraph** via [`datalayer-graphql`](../datalayer-graphql/).\n\nEach `.graphql` file in your operations directory becomes one MCP tool. Custom tools can reuse the same supergraph client for computed or aggregated logic.\n\n## Features\n\n- **Config-driven bootstrap** — `mcp-config.yaml` for supergraph URL, auth, and paths\n- **Operation discovery** — scans a directory for `*.graphql` files at startup\n- **Auto tool registration** — one MCP tool per named GraphQL operation\n- **Variable schemas** — GraphQL variables mapped to Pydantic models → JSON Schema for MCP clients\n- **Custom tool support** — `@tool` handlers (from `fastmcp.tools`) with shared `get_client()`\n- **`.env` loading** — bearer token from a file next to your config (no manual `export`)\n- **Structured errors** — federation-aware `GraphQLError` wrapped as `OperationError`\n- **Session-managed client** — reuses HTTP connections via `async with SupergraphClient`\n\n## Requirements\n\n- Python 3.13+\n- [uv](https://docs.astral.sh/uv/) (recommended)\n- [`datalayer-graphql`](../datalayer-graphql/) (workspace dependency)\n- Network access to your GraphQL endpoint\n- A valid bearer token accepted by that endpoint\n\n## Installation\n\nFrom the monorepo root:\n\n```bash\nuv sync --package datalayer-mcp\n```\n\nWith dev dependencies (for running tests):\n\n```bash\nuv sync --package datalayer-mcp --group dev\n```\n\nAs a workspace dependency in another package:\n\n```toml\ndependencies = [\"datalayer-mcp\"]\n\n[tool.uv.sources]\ndatalayer-mcp = { workspace = true }\n```\n\n## Quick start\n\n### 1.
