Looker MCP server

Checked September 2026.

Looker's managed server runs governed Explore queries and edits LookML at each Looker-hosted instance's /mcp path, with the signed-in user's permissions and only the tools an admin enables. Google's open-source MCP Toolbox does the same against customer-hosted Looker, and also runs saved Looks and creates dashboards and LookML files.

Looker MCP options

Every fact in a row comes from the publisher's own documentation.

Other ways to reach Looker data

One MCP server per tool still can't answer a cross-channel question.

Each server brings its own sign-in, its own definition of revenue, and data your assistant can't join to the rest.

SourceMedium connects 63 commerce and marketing sources, keeps one set of maintained definitions, and gives ChatGPT, Claude, and other assistants a single connection to all of it. Looker is not a SourceMedium source today.
