MCP server exposing Google Antigravity (agy CLI / Gemini): jobs, codebase analysis, file tools.
MCP server exposing Google Antigravity (agy CLI / Gemini): jobs, codebase analysis, file tools.
The idea: your primary model (Claude Desktop, Claude Code, Codex, …) stays lean and delegates the grunt work — web search, whole-repo analysis, scaffolding files, long-running edits — to a second agent running in the background. Jobs are async and unlimited: you fire a task, get a jobId instantly, and poll for the result while the caller keeps working.
The server publishes 14 tools. What each one is for:
use_antigravity — Delegate a task (async). Returns a jobId immediately. Params: prompt, thinking_depth (low/high), add_dirs (folders agy may read/write), auto_approveantigravity_continue — Continue the previous conversation (or a specific conversation_id) with a new promptantigravity_result — Get a job's result by jobId. Supports long-polling via optional wait_ms and poll_interval_ms. While running, returns a lean payload ({ status, jobIdantigravity_jobs — List recent jobs and statusesantigravity_cancel — Kill a running job by jobIdantigravity_cleanup — Delete old job files by age (older_than_hours)antigravity_create_folder — Create a folder (recursive), done directly by the serverantigravity_create_file — Create/write a text file (creates parent dirs); overwrite:false to protect existingantigravity_create_tree — Build a whole folder/file tree from a JSON specantigravity_read_file — Read a UTF-8 text file (instant); optional max_bytes capantigravity_list_dir — List a folder's entriesantigravity_models — List available models (agy models)| Need | Why | |------|-----| | Node.js 18+ | Runs this server (ships with npx/npm).
