# QueryBear
> Secure read-only MCP server for PostgreSQL, MySQL, and SQLite. Give Claude, Cursor, ChatGPT, Codex, and Windsurf safe access to your production database.
## Docs
- [Introduction](https://docs.querybear.com/index.md): QueryBear is a secure, read-only MCP server that connects AI assistants like Claude, Cursor, and ChatGPT to your production PostgreSQL, MySQL, and SQLite databases.
- [What is MCP?](https://docs.querybear.com/what-is-mcp.md): Model Context Protocol is the open standard that lets AI assistants like Claude, Cursor, and ChatGPT call external tools and read external data. QueryBear is an MCP server for databases.
- [Quickstart](https://docs.querybear.com/quickstart.md): Connect a database to QueryBear and query it from Claude, Cursor, or any MCP-capable AI client in under 5 minutes.
- [Security Model](https://docs.querybear.com/features/security.md): How QueryBear's MCP gateway protects your PostgreSQL, MySQL, or SQLite database from misbehaving AI agents, prompt injection, and accidental data exfiltration.
- [Access Control](https://docs.querybear.com/features/access-control.md): Control exactly which tables and columns each AI client can read, with enforced row limits and query timeouts — all configured per connection in QueryBear.
- [Schema Detection](https://docs.querybear.com/features/schema-detection.md): QueryBear auto-detects every table, column, and relationship the moment you connect a database — so your AI writes accurate SQL instead of hallucinating column names.
- [Custom Context](https://docs.querybear.com/features/custom-context.md): Annotate your tables and columns with plain-English descriptions so QueryBear's AI clients understand your domain and write the queries you actually mean.
- [Memory](https://docs.querybear.com/features/memory.md): QueryBear learns from the queries run against your database over time — inferring conventions, common joins, and domain meaning — and keeps an internal workspace of notes so every query gets smarter.
- [Audit Trail](https://docs.querybear.com/features/audit-trail.md): Every query, schema fetch, and connection event QueryBear handles is logged with who ran it, when, and what came back — full visibility into AI database access.
- [PostgreSQL MCP Server](https://docs.querybear.com/databases/postgres.md): Connect PostgreSQL to Claude, Cursor, ChatGPT, Codex, Windsurf, and Claude Desktop with QueryBear — a managed, secure, read-only Postgres MCP server.
- [MySQL MCP Server](https://docs.querybear.com/databases/mysql.md): Connect MySQL or MariaDB to Claude, Cursor, ChatGPT, Codex, Windsurf, and Claude Desktop with QueryBear — a managed, secure, read-only MySQL MCP server.
- [SQLite MCP Server](https://docs.querybear.com/databases/sqlite.md): Connect SQLite to Claude, Cursor, ChatGPT, Codex, Windsurf, and Claude Desktop with QueryBear — a secure, read-only SQLite MCP server.
- [Neon MCP Server](https://docs.querybear.com/integrations/neon.md): Connect Neon serverless Postgr
