Superset MCP Server

uv pip install . && mcp install main.py

Superset's REST API is broad, and this server mirrors most of it: dashboards, charts, datasets, database connections, saved queries and SQL Lab execution all have their own tools. Two of them are worth singling out before running anything, since superset_database_validate_sql checks a statement against the target database and superset_sqllab_estimate_query_cost asks what it will cost, which is a cheaper way to fail than launching a query on a warehouse. Session handling is exposed rather than hidden: the server authenticates with a username and password from a local .env, caches the token in a .superset_token file, and gives the agent superset_auth_check_token_validity and superset_auth_refresh_token so an expired session is repaired mid-task instead of breaking it. It is a community project, tested against Superset 4.1.1.
