MCP Security

MCP server security checklist for production agents

MCP is powerful because it grants tools to agents. That also means every server should be reviewed for permissions, data access, secret exposure, and failure modes before production use.

Permission scope

List exactly what the server can read, write, execute, or send over the network. Default to read-only when the workflow allows it.

Secrets handling

Never print tokens, keys, or connection strings into agent logs. Use platform secret stores and verify behavior without exposing values.

Operational evidence

Before production, run the workflow with test data, capture tool outputs, and document rollback steps for write-capable actions.
