A remote MCP server (streamable HTTP) with OAuth sign-in. Your client opens a browser to sign in to ScrollStash the first time.

**Server URL:** `https://mcp.scrollstash.com/mcp`

## Claude Code

```bash
claude mcp add --transport http scrollstash https://mcp.scrollstash.com/mcp
```

Then run `/mcp` in Claude Code and choose **Authenticate** for `scrollstash`.

Custom MCP connectors need a plan and workspace setting that allow them (developer mode). Add a connector with the server URL `https://mcp.scrollstash.com/mcp` and OAuth authentication, then sign in.
