Enables Claude Code, Cursor, OpenCode/LunaCode, and other MCP clients to invoke the harness's shell, file, code, scheduling, and device-control tools over stdio.
Enables MCP-compatible hosts such as OpenCode to drive the Codex CLI through codex app-server over stdio, exposing tools to run prompts, inspect status, list threads, and interrupt running turns.
Enables an AI agent to run local tools on the user's own machine via stdio, including command execution, workspace file read/write, and system status checks.
Enables MCP clients to discover and execute operational tools such as database mutations and system diagnostics over stdio, with deterministic structured outputs and Langfuse observability.
