---

ChatGPT connects to squirrelscan through a custom MCP connector (developer mode). Once added, you can run audits and ask questions about the findings straight from a chat.

<Note>ChatGPT is a chat client, not a coding agent, so it uses the hosted MCP server only, no CLI, skills, or local file edits. To have an agent fix issues in your codebase, use [Claude Code](/developers/agents/claude-code), [Cursor](/developers/agents/cursor), [Codex](/developers/agents/codex), or [opencode](/developers/agents/opencode).</Note>

## Requirements

- A ChatGPT **Plus, Pro, Business, Enterprise, or Education** account (developer mode is not on Free).
- ChatGPT only supports **remote** MCP servers over HTTPS, which is exactly what squirrelscan hosts.

## 1. Enable developer mode

Open **Settings → Connectors → Advanced**, and turn on **Developer mode**. (Connectors were renamed **apps** in late 2025; the toggle is the same.) On a workspace, an admin may need to enable custom connectors under **Permissions & Roles** first.

## 2. Add the connector

1. Go to **Settings → Connectors** and click **Create** (or the **+**).
2. Give it a name, `squirrelscan`.
3. Set the MCP server URL:

   ```
   https://mcp.squirrelscan.com/mcp
   ```

4. Choose **OAuth** for authentication and save. ChatGPT discovers the authorization server and runs a browser sign-in, so nothing secret is stored.

## 3. Run an audit

Start a chat, enable the **squirrelscan** connector for the conversation, and ask:

```
Audit https://example.com and summarize the top 10 issues by severity.
```

ChatGPT calls the squirrelscan tools, waits for the audit to finish, and reads the report back. Cloud audits spend [credits](/cloud/credits); a base charge starts the run and pages are charged as they render.

<Warning>Developer-mode connectors give a model write access to third-party tools. Only enable connectors you trust, and review actions ChatGPT proposes before approving them.</Warning>
