leo mcp-server

Run the Leo MCP server on stdin/stdout.

Internal command

You do not invoke this directly. Leo wires it into every supervised agent's and task's MCP config automatically. It is documented here so operators know what it does and where to look when debugging.

Usage

leo mcp-server

Description

Speaks the Model Context Protocol over stdin/stdout. Supervised Claude agents dispatch the universal channel slash commands — /clear, /compact, /stop, /tasks, /agent, /agents — by calling the leo_* tools this server exposes.

Environment

mcp-server reads two variables injected by the Leo supervisor:

Variable Purpose
LEO_PROCESS_NAME Identifies the calling agent or task so tool actions target the right one, e.g. <agent-name> for an agent (including one backing a runtime: persistent task) or task:<name> for a one-shot task.
LEO_WEB_PORT Daemon HTTP API port used by mcp-server to drive agent/task actions.
