MCP server that orchestrates Claude Code, Codex, Gemini CLI, and Copilot CLI through a unified stdio interface — ask, compare, verify, and collaborate across multiple AI agents.

All-Agents-MCP

⚠️ Archived — This project is no longer actively maintained.

As the AI agent CLI ecosystem has evolved, direct CLI invocation + Skills-based integration has become the more practical and mainstream approach over wrapping agent CLIs behind an MCP server.

The core functionality of this project has been merged into hardened-claude-code as Skills. The same multi-agent orchestration can now be achieved more concisely and maintainably through CLAUDE.md configuration and Skills.

Migration guide:

• Tools like ask_agent, ask_all, delegate_task → replaced by Skills in hardened-claude-code (/with, /web-fetch, etc.)
• No MCP server setup required — Skills invoke CLIs directly
• Environment variable model config → consolidated into declarative CLAUDE.md settings

Original README below for reference.

An MCP server that orchestrates multiple AI CLI agents — Claude Code, Codex, Gemini CLI, and Gemini CLI — through a unified interface. Delegate tasks, run cross-agent comparisons, and leverage each agent's strengths from any MCP-compatible host.

Safe by Design — No OAuth Token Hijacking

Some multi-agent tools work by extracting OAuth tokens from other AI services and calling their APIs directly. This approach (used by projects like OpenCode) violates the terms of service of those platforms and can result in account suspension or permanent bans.

all-agents-mcp takes a fundamentally different approach. It invokes each agent's official CLI binary (gemini, codex, gemini, gemini) as a child process — exactly the same way a human would use them in a terminal. No tokens are extracted, no APIs are called behind the scenes, and no authentication is bypassed.
