Sigma MCP Server
Sigma's first-party remote Model Context Protocol server. AI assistants such as Claude, ChatGPT, Codex, Cursor and Snowflake Cortex Code connect over HTTP with OAuth and can then search a Sigma organization for workbooks, data models, reports and warehouse tables, describe their columns and semantics, and run governed queries in natural language. Permissions are inherited from the caller's own Sigma account rather than a service identity, and MCP-issued warehouse queries are tagged "kind":"mcp" so their cost can be attributed.
