Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

`EMAILSERVER_DATABASE_URL` Required	PostgreSQL connection URL. This server keeps its own index and does not run without a database; the repository ships docker-compose files that start one for you.

`EMAILSERVER_API_TOKEN` Optional, secret	Bearer token required in single_user mode. At least 32 characters, or the server refuses to start.
`CREDENTIAL_ENCRYPTION_KEY` Optional, secret	Key used to encrypt stored mailbox credentials at rest. Generate with: openssl rand -base64 32
