# Connect a client

> Add the Summand MCP server to claude.ai, ChatGPT, and other OAuth-aware MCP clients.

The Summand MCP server is a remote, OAuth-authenticated streamable-HTTP endpoint. There is nothing to install — every client uses the same URL and follows the standard OAuth discovery flow.

## Endpoint

```
https://mcp.summand.com/mcp
```

The endpoint is stateless: each request constructs a fresh server instance scoped to the bearer token in the `Authorization` header.

## Troubleshooting

* **Client can't discover the MCP server** — make sure you're using the full endpoint URL with `/mcp` at the end. `https://mcp.summand.com` on its own will not work — it must be `https://mcp.summand.com/mcp`.
* **`401` on every call** — your token expired or was revoked. Disconnect and reconnect the integration in your client.
* **`403 Forbidden`** — the resource isn't owned by or shared with your user. Check sharing in the dashboard.
