An MCP server named agy that starts a Node.js program for the AGY plugin. MCP is a way for an agent to connect to external tools through a standard server.

Use it to start the AGY plugin's MCP connection when its server script is available.

The excerpt only identifies the server and how it is launched, not the tasks it provides.

agy — MCP server by iicmaster/antigravity-plugins

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add iicmaster/antigravity-plugins

Claude Code

/plugin install agy

Installing this writes the configuration, not the program: `bash` has to be on your PATH already, or the server will not start.

Made for: Claude Code.

Or install agy, the plugin that ships this one along with the rest of its 5 skills, 7 commands, 1 agent, 1 MCP server.

Security

Grade A, and why

agy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
