A lightweight MCP bridge that lets Claude Code delegate heavy tasks to the Antigravity CLI (agy) - saving context window and tokens for what matters.
What It Does
Registers a delegate_to_agy MCP tool that Claude automatically uses when it encounters:
- Large files (>200 lines) - logs, dumps, generated code
- Multi-file analysis (>3 files at once)
- Deep searches -
git log,git diff,grep - Web lookups - documentation, external knowledge
- Adversarial review / plan critique - always delegated
Claude sends a prompt + file paths → the bridge runs agy CLI → returns the result.
Requirements
- Python 3.10+
agyCLI installed and authenticated- Claude Code
Installation
> Note: The command below uses uvx to run the server without manual installation. If you don't have uv installed, you can substitute uvx with npx -y or pipx run.
# 1. Register the MCP server globally via uvx
claude mcp add -s user claude-to-agy uvx claude-to-agy
# 2. Download the delegation rules into your current project
curl -o CLAUDE.md https://raw.githubusercontent.com/rauls-kjarners/claude-to-agy/main/CLAUDE.md
That's it. Claude will now automatically delegate heavy tasks to Antigravity CLI in any project that has the CLAUDE.md file.
> Tip: To enable globally without copying CLAUDE.md per project, add the rules to ~/.claude/CLAUDE.md instead.
Using as a Skill
This project also includes a SKILL.md file, which is the standard format for reusable Claude Code skills. If your setup supports skills, you can use it instead of manually copying CLAUDE.md:
claude skill add https://raw.githubusercontent.com/rauls-kjarners/claude-to-agy/main/SKILL.md
> Note: You still need the MCP server registered (step 1 above). The skill provides the rules, MCP provides the tool.
Configuration
All settings are optional environment variables:
| Variable | Default | Description | | --------------------- | ------- | --------------------------------- | | AGY_CONNECT_TIMEOUT | 60 | Seconds to start the agy process | | AGY_TOTAL_TIMEOUT | 1200 | Hard timeout for entire execution |
How It Works
User → Claude Code → MCP bridge (FastMCP) → agy CLI → Gemini API
