Add a connector that isn't in the directory changedconnectors/custom/add-unlisted

Nearest release: v2.1.283, published under an hour after upstream edited the page. Shown because the two are within 24 hours of each other. Nothing here says the release caused the edit.

33> Connect Claude to an MCP server that isn't in the Connectors Directory, by its URL or as a local desktop extension.

5You can connect Claude to a [Model Context Protocol (MCP)](/docs/connectors/building/mcp) server that isn't listed in the [Connectors Directory](/docs/connectors/directory). You add a remote server by its URL as a custom connector. In Claude Desktop, you can also use a desktop extension, which runs the server on your own computer.

116116* **Use Claude's published identity**: the recommended option. The server reads Claude's client details from a Client ID Metadata Document that Anthropic hosts. You set nothing up, and the server must support this method
117117* **Register automatically**: Claude registers OAuth clients with the server as users connect, using Dynamic Client Registration. This works with most servers and adds client registrations over time
118* **Use your own OAuth client**: enter a client ID you registered with the server. Leave the secret blank unless your authorization server requires one. See [Authentication for connectors](/docs/connectors/building/authentication)

120120For **Request headers**, add fixed credentials such as API keys that Claude sends on every request. See [Authenticate with request headers](#authenticate-with-request-headers).

222222 
223If you're authoring the extension, follow [Build a desktop extension with MCPB](/docs/connectors/building/mcpb) and the [MCPB documentation](https://github.com/modelcontextprotocol/mcpb). You build your MCP server, bundle it with MCPB, test it locally, and then deploy it to your organization.

227Some connectors in the directory are verified by Anthropic and others are community connectors, as [connector verification](/docs/connectors/verification) explains. A connector you add yourself connects Claude to an unverified service.
