Server Configuration

Describes the environment variables required to run the server.

NameRequiredDescriptionDefault
AGY_EXENoExplicit path to agy.exe. Auto-detected if not set.
AGY_MODELNoDefault model ID used by the agent.gemini-3.8-flash-high
CLOUD_CODE_URLNoSet only if using a custom local unlock proxy.
AGY_ACCESS_TOKENNoAccess token used for authentication on Linux and macOS.
AGY_AGENT_TIMEOUTNoTimeout in seconds before terminating long runs.900
AGY_DEFAULT_WORKSPACENoDefault workspace granted to the agent. Set to 'none' to isolate.process.cwd()

Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Tools

Functions exposed to the LLM to take actions

NameDescription
ask-antigravityA

Ask the Google Antigravity AGENT (Gemini 3.8 Flash / Pro) — a coding agent WITH file tools (Read/Write/Bash), like a second Claude Code / Codex.

By default it works in the current directory (process workspace), so it can read and run your repo like Codex. Supports parallel multi-agent swarm execution and one-click session resume.

Parameters:

  • prompt: The task/code instruction.

  • resume: If True, automatically continues the most recent conversation session (--continue) without needing an ID.

  • prompt_file: Absolute path to a file containing the prompt (wins over prompt).

  • model: Model ID (default: gemini-3.8-flash-high, or gemini-3.1-pro-high, etc.).

  • system: Optional system instructions.

  • system_file: Absolute path to a file containing system instructions.

  • workspace: Directory granted to the agent via --add-dir (read+write). Default: current directory. Pass 'none' for isolated temp dir.

  • conversation_id: Resume/continue an existing session by conversation ID.

  • effort: Reasoning effort (low, medium, high).

  • cleanup: If true, delete prompt_file / system_file after execution.

  • save_artifact: If true, always saves response to an artifact file in .antigravity/artifacts/.

ask-geminiD

Alias for ask-antigravity.

review-diffA

Perform an automated, structured code review on current uncommitted or staged git changes. Runs in strictly read-only mode so it never modifies your repository files.

Parameters:

  • workspace: Path to the git repository (default: current workspace).

  • staged: If true, reviews only staged changes (git diff --staged). Otherwise reviews all uncommitted changes.

  • focus: Optional focus area (e.g. 'security', 'performance', 'logic bugs', 'code style').

  • model: Target model ID (default: gemini-3.7-flash-high).

check-quotaA

Retrieve and display live remaining quota percentages for all Google Antigravity models. Shows health status (Healthy / Low / Depleted) for each model.

generate-testsA

Generate thorough unit tests for a specified source code file.

Parameters:

  • target_file: Relative or absolute path to the file you want to test.

  • test_framework: Test framework (e.g. 'pytest', 'unittest', 'jest', 'go test'). Default: 'pytest'.

  • workspace: Workspace root directory.

  • write_to_file: If True, writes the generated tests directly into output_file.

  • output_file: Destination file path for generated tests (e.g. 'tests/test_auth.py').

  • model: Target model ID (default: gemini-3.8-flash-high).

pingB

Health check — verifies that the Antigravity CLI or backend responds.

list-modelsA

List available models in Google Antigravity.
