MCP servers for databases

Database MCP servers give AI agents read or write access to a database through tools. Because live database credentials carry real risk, treat a database server as a read-only surface for agent callers by default and constrain its schema scope.

Evaluate the connection mechanism, whether read-only mode exists, and what queries the exposed tools can run. Prefer a server whose tool surface you can bound to the minimum tables a task needs.

Granting a model a write-capable database tool means any crafted query can change data. Prefer servers that support a read-only mode and limit the connected role to SELECT where possible.
