# Connect Gemini to Stuff

Use Gemini's **Custom apps** flow in the web app. This guide covers consumer Gemini; workspace-managed Google accounts can have different capabilities. You do not need Node.js, a repository checkout, `claude_desktop_config.json` or a local MCP configuration for this browser flow.

If Gemini cannot open the setup link, use the steps below directly. The guide is public; a fetch failure is not evidence that Stuff requires authentication to read it. In an October 5, 2026 test, Gemini 3.5 Flash-Lite failed to read the public guide and offered incorrect local setup instructions. A Pro retry produced mixed results, so changing models alone is not a verified fix. The connection-settings route below remains the intended path.

## Add the connection

1. Open **Settings → Connected Apps**. This may be under **Personal Intelligence**.
2. Under **Custom apps**, choose **Add custom app**.
3. Enter `https://stuff.ac/mcp` and choose **Next**. Leave optional client credentials empty; Stuff supports automatic registration.
4. Review Gemini's notice, sign in to Stuff, and approve only the spaces and permissions needed.
5. In a conversation, use `@` to select Stuff explicitly.

Google currently documents this flow for eligible personal accounts in the US, age 18+, English, with Keep Activity on. Google says a connection added on web is available on mobile too; we have not independently verified mobile setup here. Review the implications of activity settings before changing them.

*Actual October 1 setup screen. “This MCP server is already connected” is expected when Stuff is already present. Use its existing entry; do not create duplicates.*

## Try it

> @Stuff.ac Read Project Lantern.md from my connected space and summarize its brief. Give me the file link. Do not change anything.

Then try the [two-assistant handoff](https://stuff.ac/file/552c90a8-384e-4263-b71d-84c30beb2df1). Gemini's Stuff connection has been exercised with reads, file creation, exact edits, version checks, and denial outside the selected space. Interactive in-chat rendering has not been verified here; expect tool results and a link to the Stuff viewer.

## Inspect and disconnect

Open Stuff's details under Connected Apps. Gemini displays its connection state and available tools. **Disconnect** stops using the connection in Gemini; **Remove app** removes the app entry. Revoke the matching grant in **Stuff → Agents** as well when you want to ensure future Stuff requests are denied.

*The existing connection was left intact. The separate demo-key revocation was tested in Stuff; see the [before/after walkthrough](https://stuff.ac/file/e7263199-8d02-4e17-848b-866b6d44b827).*

Gemini's notice describes exchanges of chat and other context with custom apps. Your Stuff permissions limit which Stuff resources can be accessed; they do not replace Google's own data controls or policies.
