Connect UseAgents to Antigravity so your AI assistant can discover verified developer tools from the registry. Antigravity offers two products that support MCP — the Antigravity IDE and the Gemini CLI.
UseAgents is currently free during our public beta. No API key is required. Requests are subject to rate limits.

Antigravity IDE

Option 1: MCP Store

  1. Open the side panel in Antigravity IDE.
  2. Click the ”…” (three dots) dropdown at the top of the panel.
  3. Select MCP Store.
  4. Search for UseAgents and click Install.

Option 2: Manual config

If UseAgents is not listed in the MCP Store, add it manually:
  1. Open the ”…” dropdown → MCP StoreManage MCP Servers.
  2. Click View raw config to open the mcp_config.json file.
  3. Add the UseAgents server:
  1. Save the file. The IDE will automatically detect the changes.

Verify

  1. Ensure you are in Agent Mode (toggle in the chat interface).
  2. Ask the agent to search for a tool — for example: “Use UseAgents to find a TypeScript SDK for Stripe.”
  3. Confirm you receive structured tool results.

Gemini CLI

Option 1: CLI command

Run this in your terminal:

Option 2: Settings file

Edit the settings file to add UseAgents manually. Add the UseAgents MCP server configuration to the file:

Verify

  1. Start a Gemini CLI session.
  2. Type /mcp to list all active MCP servers and confirm UseAgents appears.
  3. Ask the agent to search for a tool using search_tools.

Troubleshooting

  • Server not detected in IDE: Save the config file and wait a moment — the IDE auto-detects changes without a restart.
  • Agent not using tools: Make sure you are in Agent Mode, not the standard chat mode.
  • CLI add command fails: Try editing the settings file manually instead.
