How It Works

SQL query engine on SQLite. anyquery mcp --stdio turns it into an MCP server. Agent discovers tables, writes SQL.

54 plugins: Notion, GitHub, Slack, Gmail, Salesforce, Airtable, Google Sheets, Docker, and more. Plus CSV/JSON/Parquet files and MySQL/PostgreSQL/DuckDB/ClickHouse databases.

Cross-Source Joins

SELECT g.title, n.status
FROM github_issues g
JOIN notion_tasks n ON g.title = n.name
WHERE g.state = 'open' AND n.status != 'Done'

One query replaces fetching from multiple APIs and correlating in context.

Trade-offs

• AGPLv3 — evaluate for commercial use
• Plugin setup — each plugin needs its own credentials
• Read-heavy — most plugins read-only, write support varies

Rating: 4.0/5 — Widest data access surface of any single MCP server.
