### Description (declared)

# antigravity-cli-mcp-slim

A thin, auditable [MCP](https://modelcontextprotocol.io) server wrapping the [Antigravity CLI](https://github.com/google-antigravity/antigravity-cli) (`agy`).

## Why

When you add an MCP server to your AI coding tool, every prompt and code snippet
you send flows through that wrapper. Most CLI-wrapping MCP servers are small,
individually maintained packages — and recent supply-chain incidents
(`xz-utils`, `postmark-mcp`, the npm `chalk`/`debug` compromise) show that
"small and useful" is not the same as "safe to trust blindly."

This project takes the opposite stance: instead of asking you to trust it, it
tries to be **easy to audit**.

- **Single file** — the whole server is `src/antigravity_cli_mcp_slim/server.py`,
  readable end-to-end in one sitting
- **One third-party dependency** (`mcp`) — minimal supply-chain surface
- **Faithful CLI mapping** — every typed parameter mirrors a real `agy` flag by
  name, so it is obvious which flags an invocation actually sets
- **Forward-compatible** — any new or uncommon `agy` flag is reachable via
  `extra_args` without touching this server
- **Configurable binary path** — `$AGY_CMD` lets you swap or wrap the `agy` binary
- **Transparent** — every invocation logs the exact argv to stderr

Read `server.py` before you install. That is the point.
