metabase-mcp-pro 0.1.0

Agent-first Metabase MCP server with a pluggable, table-scoped query-guardrail layer.

metabase-mcp-pro

An agent-first Model Context Protocol (MCP) server for Metabase with a pluggable, table-scoped query-guardrail layer.

It combines the lean ergonomics of Metabase's first-party MCP (guided MBQL builder, URI-addressed reads, pagination) with the full reach of the Metabase REST API (models, metrics, dashboards, admin — plus a generic API passthrough so nothing is out of reach), and adds the layer neither has: query guardrails that are safe-by-default, explicitly overridable, and never silently filter, plus an output sanitizer that strips connection secrets and trims token bloat.

White-label

No embedded brand, no environment defaults, no shipped table registry. Everything organization-specific (which tables are CDC, which need crawler exclusion, the vetted-query catalog) is supplied at runtime via env / config.

Configure

Env var	Purpose
METABASE_URL	Metabase base URL (required; no default)
METABASE_API_KEY	API key, sent as x-api-key
METABASE_MCP_GUARDRAILS_CONFIG	path to a guardrails.yaml (see examples/)
METABASE_MCP_READONLY	1 to hard-disable all writes

Run

uvx metabase-mcp-pro

Requires only uv — it installs the package from PyPI on demand.

Use it in another project

It's white-label, so any project reuses it by adding one MCP-server entry and supplying its own config. Drop this into a plugin manifest's mcpServers (or ~/.claude.json):

"metabase": {
  "command": "uvx",
  "args": ["metabase-mcp-pro"],
  "env": {
    "METABASE_URL": "https://metabase.your-org.com",
    "METABASE_API_KEY": "...",
    "METABASE_MCP_GUARDRAILS_CONFIG": "/path/to/your-project/guardrails.yaml"
  }
}

Each consumer brings its own METABASE_URL, API key, and guardrails.yaml (start from examples/guardrails.example.yaml) — nothing project-specific is baked into the package.
