Anyquery

Anyquery is a free, open-source desktop tool and MCP server that connects over 40 sources—including GitHub, Notion, Spotify, Gmail, Airtable, Google Sheets, CSVs, Parquet, Postgres, Salesforce, and more—turning them into queryable tables with a single, SQL-like dialect. It allows users to run queries and manage data locally without cloud involvement, and supports integration with BI tools as well as conversational AI agents (like Claude, ChatGPT, Cursor) via the MCP protocol for natural language data querying and manipulation. Designed for data enthusiasts and professionals, it also lets you 'write-back' to services (e.g., insert into Notion or Google Sheets) and supplies a community-sourced query hub.
