Your AI agents can now call each other.

An MCP server that lets Claude Code, Codex CLI, and Gemini CLI invoke each other as tools. No glue scripts. No copy-paste. Just agents collaborating.

Why?

Each CLI agent has strengths. Sometimes you want Claude to implement, Codex to review, and Gemini to sanity-check. Weft makes that one tool call away.

Quick Start

git clone https://github.com/cipher982/weft && cd weft
uv sync
uv run agent-mesh doctor   # verify setup (no API calls)
uv run agent-mesh smoke    # test it works (costs money)

Register the MCP Server

Claude Code:

claude mcp add-json agent-mesh '{"type":"stdio","command":"uv","args":["run","python","-m","agent_mesh.mcp_server"]}'

Codex:

codex mcp add agent-mesh -- uv run python -m agent_mesh.mcp_server

Gemini: Add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "agent-mesh": {
      "command": "uv",
      "args": ["run", "python", "-m", "agent_mesh.mcp_server"]
    }
  }
}

Your agent now has three new tools: claude_run, codex_exec, gemini_run.

Prerequisites

npm install -g @anthropic-ai/claude-code  # then: claude auth
npm install -g @openai/codex               # needs: OPENAI_API_KEY
npm install -g @google/gemini-cli          # needs: GEMINI_API_KEY

Troubleshooting

Problem	Fix
Command not found	which claude codex gemini - install missing CLIs
Auth failed	Run claude auth or set API key env vars
MCP server not found	Restart your agent CLI after registering
