Claudius Corp provides two ways for AI agents to communicate with the workflow engine:

In-Process Bridge (Primary) #

The MCP Bridge is the primary communication channel. It runs in-process with the Claudius Corp application, giving agents direct access to workflow state.

• Protocol: JSON-RPC 2.0 over TCP
• Host: localhost
• Port: Dynamic (written to MCP_PORT_FILE at startup)
• Used by: Agents spawned by the application for workflow phases

Standalone MCP Server #

The Standalone MCP Server reads JSON-RPC from stdin and writes responses to stdout. It connects to the database directly.

• Protocol: JSON-RPC 2.0 over stdin/stdout
• Entry point: McpServer.main()
• Required: DMSI_DB_PATH environment variable
• Used by: Agents running independently outside the main application
