Remote MCP servers let a supported client connect to a hosted endpoint. You do not need to launch that server as a local process, but you still need a compatible client, network access and the authentication required by the service.
A service's homepage or GitHub repository is not interchangeable with its MCP URL. Copy the documented endpoint and choose the transport the service supports. Older SSE configurations and Streamable HTTP configurations can differ; adding an arbitrary path to a website will not turn it into an MCP server.
OAuth connections authorize an account through the provider's sign-in flow. API-key connections require the documented header or credential setting. Confirm the workspace and scopes before asking an assistant to read private data or write to a service. A successful connection does not prove it has permission to every resource.
Check that the endpoint is reachable, the client supports its transport and authentication, and the credentials belong to the intended account. Then inspect the tool list and try one simple read. If connection works but a tool fails, review resource permissions and the tool's required arguments.
Start with Figma's official server, Notion or GitHub when those services match your task. Browse official integrations and the full directory for other options.
