A full-featured [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server for the [Looker API](https://cloud.google.com/looker/docs/reference/looker-api/latest). Gives AI assistants direct access to your Looker instance — querying the semantic model, managing content, editing LookML, and administering users — all through a standard MCP interface.

## Features

- **160 tools** across 15 groups covering the full Looker API surface
- **Semantic layer queries** — query through LookML models, not raw SQL
- **OAuth pass-through** — forward user tokens from an upstream gateway or MCP OAuth flow
- **User impersonation** — admin sudo on self-hosted Looker, OAuth on Google Cloud core
- **Dual transport** — stdio for local/CLI use, streamable-http for production deployment
- **Both MCP protocol eras** — one endpoint serves 2025-11-25 clients (`initialize` handshake, `Mcp-Session-Id` sessions) and 2026-07-28 clients (no handshake, no session). Built on FastMCP 4 and the MCP Python SDK 2. See [Protocol Eras and HTTP Sessions](#protocol-eras-and-http-sessions)
- **Selective tool loading** — enable only the tool groups you need via `--groups`
- **Pluggable…
