How do I install the a2db mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `DB_PASSWORD` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the A2db MCP Server?

Give AI agents safe, read-only access to your databases. One call, multiple queries, clean results.

What you get

Pre-configured connections — — define databases in .mcp.json with --register, agent queries immediately
Batch queries — — run multiple named queries in a single tool call
Default connection — — set connection once, use it across all queries in a batch
Clean output — — structured JSON envelope with compact TSV data and per-query timing (see why TSV?)
Read-only enforced — — SQLGlot AST parsing blocks all write operations
All drivers bundled — — pip install a2db and you're done
