Antigravity Setup Guide

Antigravity is an agentic AI IDE environment developed by Deepmind. It supports native, lazy-loaded Model Context Protocol (MCP) servers, allowing the Antigravity agent to autonomously fetch and invoke local tools during compilation and code correction loops.

1. Registering the MCP Server Directory

Antigravity reads active server specifications and lazy-loaded tool schemas from its local application data directory. You can register Proxima by setting up the schemas folder:

Local App Data Paths

# Windows Location: C:\Users\Admin\.gemini\antigravity-ide\mcp\proxima # macOS Location: ~/.gemini/antigravity-ide/mcp/proxima

Registration Steps

1 Create a folder named proxima inside the Antigravity mcp directory.

2 Export the tools JSON schema declarations from the Proxima Application (Settings → Export Schemas) into this folder.

3 Add an optional instructions.md file inside the same folder to help the Antigravity model choose when and how to call your tools.

2. Local Customization Rules (Skills)

Antigravity supports customized execution contexts (Skills and Rules) at a project level. You can add specific rules to guide the agent when collaborating with Proxima:

Creating Custom Rules

Create a file named AGENTS.md inside your workspace customizations folder, .agents/:

# Workspace Rules (.agents/AGENTS.md) When performing web queries, always delegate to the proxima `deep_search` tool. When analyzing or optimizing code blocks, run `optimize_code` through Proxima. If compilation failures occur, run `solve` to activate the self-healing compilation loop.

Antigravity automatically discovers and parses these instructions, adjusting its query routing to use the local Proxima server configuration.
