337For the streamable HTTP transport, use `"type": "http"` instead. In `.mcp.json` and other JSON config files, `"streamable-http"` is accepted as an alias for `"http"`. The programmatic `mcpServers` option accepts only `"http"`.

616In the `MCP servers:` line, a `status` of `connected` for `github` confirms the token works. If Claude Code has a [cached tool list](#connection-timing) for the server, the status can read `pending` instead and the server connects on its first tool call. If the status is `failed` or `needs-auth`, see [Error handling](#error-handling) before trusting the result, since Claude can fall back to built-in tools when the server is unavailable.
