Query your apps like they're SQL tables, then let an LLM join

What it does Anyquery is a SQL query engine built on SQLite that uses plugins to expose files, databases, and apps—such as Notion, GitHub, or Apple Notes—as ordinary tables. It can also impersonate a MySQL server, letting standard BI clients like TablePlus or Metabase connect without knowing anything about the underlying plugin system. On the other side, it offers LLMs access to the same data through the Model Context Protocol and function calling.

The interesting bit Instead of asking you to adopt a new wire protocol or data format, it meets existing tools on their own terms. By translating between SQLite-backed plugins and both MySQL clients and MCP consumers, it acts like a polyglot middleware layer that happens to speak SQL fluently.

Key highlights

• Query engine built on SQLite with a plugin registry covering 40-plus integrations.
• MySQL-compatible server mode for standard analytics and database clients.
• LLM connectivity via MCP and function calling.
• Supports loading native SQLite extensions alongside custom plugins.
• Core engine licensed under AGPLv3; RPC library is MIT; individual plugins carry their own terms.

Caveats

• The maintainer currently accepts only minor contributions, so large community-driven changes may be slow to land.
• Plugin licensing is per-author and per-plugin, which adds legal homework before commercial use.

Verdict Worth a look if you need to run ad-hoc analytics across scattered SaaS tools without standing up an ETL pipeline, or if you want to hand an LLM structured context from apps that lack native MCP support. Skip it if your data already lives in a single, well-behaved warehouse.
