claude-to-agy

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 3.12+

• agy CLI installed and authenticated

• Claude Code

Installation

# 1. Clone anywhere on your machine
git clone https://github.com/rauls-kjarners/claude-to-agy.git ~/.claude-to-agy

# 2. Register the MCP server (global - works in any project)
claude mcp add -s user claude-to-agy python3 ~/.claude-to-agy/src/bridge.py

# 3. Copy the rules file into any project where you want delegation
cp ~/.claude-to-agy/CLAUDE.md /path/to/your/project/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 ~/.claude-to-agy/SKILL.md

Note: You still need the MCP server registered (step 2 above). The skill provides the rules, MCP provides the tool.

Configuration

All settings are optional environment variables:

How It Works

User → Claude Code → MCP bridge (bridge.py) → agy CLI → Gemini API
                   ←                        ←         ←

1. CLAUDE.md instructs Claude when to delegate

2. Claude calls delegate_to_agy(prompt, files) via MCP

3. bridge.py reads the files, prepends them to the prompt

4. Runs agy -p "<prompt>"

5. Returns {"success": true, "response": "..."} or {"success": false, "error": "..."} back to Claude
