Use Hutch from
Antigravity.
Google's agentic IDE, paired with a persistent data layer.
Antigravity is Google's agent-first development environment. Agents plan, execute, and review code on your behalf. Hutch gives them a place to leave the artifacts behind: surfaced bugs, decisions, work queued for later.
Hutch attaches as a remote MCP server, with OAuth for auth.
Install
Fastest: paste this into Antigravity and it sets itself up. You approve the sign-in in your browser.
Connect Hutch (hutchdb.com) to Antigravity as an MCP server.
- URL: https://app.hutchdb.com/api/mcp
- Transport: remote streamable HTTP
- Auth: OAuth (no API key). I'll approve in the browser.
How to do it in Antigravity:
- In ~/.gemini/config/mcp_config.json, add under "mcpServers": "hutch": {"serverUrl": "https://app.hutchdb.com/api/mcp"} (Antigravity requires serverUrl, not url).
- You can't run the OAuth login yourself: tell me to open Agent settings > Customizations and click Authenticate next to hutch.
1. Add the server for my user account, not just this project, so it works everywhere.
2. Start the OAuth login, or tell me exactly what to click if you can't start it yourself.
3. Tell me if I need to restart or reload you. Then call hutch_list_collections to confirm it works.Or set it up by hand:
01Step 1. Configure
In the agent side panel, click … > MCP Servers > Manage MCP Servers > View raw config.
Add Hutch to mcp_config.json:
{
"mcpServers": {
"hutch": {
"serverUrl": "https://app.hutchdb.com/api/mcp"
}
}
}Global config lives at ~/.gemini/config/mcp_config.json; per-project at .agents/mcp_config.json. Antigravity requires serverUrl, not url.
02Step 2. Authenticate
Open Agent settings (Cmd/Ctrl + ,) > Customizations and click Authenticate next to hutch. Sign in with GitHub or Google, approve, then paste the authorization code back and click Submit.
03Step 3. Try it
Ask your agent:
- >"Store this article in my Hutch reading-list collection."
- >"Save the bugs we just discussed to a "tickets" collection in Hutch."
- >"What collections do I have in Hutch?"
- >"Find my notes about caching in Hutch."
