Gemini antigravity bridge: MCP server, setup and security

What Gemini antigravity bridge does

According to its repository: “Bidirectional bridge between Gemini Spark and the Antigravity IDE: coding subagent dispatch, shared memory, local file operations and Spark app orchestration.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Gemini antigravity bridge is listed under Coding agents, a category of 151 servers in the directory, where it ranks #130 by stars.

Topics declared by the repository: developer-tools, gemini, google-cloud, python, ai-agents, automation.

Installing and connecting Gemini antigravity bridge

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Python. Listed systems: macOS, Windows, Linux.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Gemini antigravity bridge. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on August 19, 2026, the nandhakumar-murugan/gemini-antigravity-bridge repository has 14 stars and 3 forks, with 0 open issues. It has more stars than 32% of the servers in the directory. It received changes this month.

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
