Sub Agents MCP Overview

sub-agents-mcp lets MCP-compatible clients run reusable coding agents defined in Markdown files, using a configured coding CLI as the backend. It supports tasks such as code review, test writing, investigation, and documentation, and can continue an agent across calls when sessions are enabled. Reach for it when several MCP clients should share the same agent definitions, backend, and model settings. Supported backends include Codex, Claude Code, Cursor CLI, Gemini CLI, OpenCode, and others.

Primary Use Cases for Sub Agents MCP:
  • Delegate code reviews to a reusable reviewer agent
  • Generate unit tests with a dedicated test-writing agent
  • Investigate failed requests through a focused debugging agent
  • Document API changes with a reusable documentation agent
