Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| AGY_EXE | No | Explicit path to agy.exe. Auto-detected if not set. | |
| AGY_MODEL | No | Default model ID used by the agent. | gemini-3.8-flash-high |
| CLOUD_CODE_URL | No | Set only if using a custom local unlock proxy. | |
| AGY_ACCESS_TOKEN | No | Access token used for authentication on Linux and macOS. | |
| AGY_AGENT_TIMEOUT | No | Timeout in seconds before terminating long runs. | 900 |
| AGY_DEFAULT_WORKSPACE | No | Default 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
| Name | Description |
|---|---|
| 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:
|
| 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:
|
| 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:
|
| pingB | Health check — verifies that the Antigravity CLI or backend responds. |
| list-modelsA | List available models in Google Antigravity. |
Prompts
Interactive templates invoked by user choice
| Name | Description |
|---|---|
| code-review | Prompt template for structured, senior-level code review of a diff or implementation. |
| tdd-feature | Prompt template for Test-Driven Development (TDD): write failing tests first, then implement. |
| security-audit | Security audit prompt template focusing on OWASP Top 10, sanitization, authentication, and CVE patterns. |
Resources
Contextual data attached and managed by the client
| Name | Description |
|---|---|
| quota_resource | Live remaining quota percentages for Google Antigravity models. |
| models_resource | List of available models in Google Antigravity. |
| status_resource | Active Google Antigravity runtime status and configuration. |
TDQS
Scored across 7 tools
Most tools have clearly distinct purposes: asking the agent, reviewing diffs, generating tests, checking quota, listing models, and health checking. The only overlap is ask-gemini being explicitly documented as an alias for ask-antigravity, so while redundant, it does not create real selection ambiguity.
All tools follow a consistent lowercase hyphenated verb-noun pattern: ask-antigravity, review-diff, check-quota, generate-tests, list-models. Even ping fits the simple verb style, and there are no mixed naming conventions.
Seven tools is a well-scoped set for an Antigravity integration. Each tool covers a meaningful capability, and the only minor redundancy is the explicitly marked ask-gemini alias.
The server covers the main workflows: invoking the agent, reviewing changes, generating tests, checking quota/model availability, and health checks. Session resume and workspace control are handled through ask-antigravity parameters, so there are no critical gaps, though a dedicated session-management tool could be a potential enhancement.
