We connected the 7shifts MCP server (https://developers.7shifts.com/mcp) to Claude as a custom connector, with an access token in the Authorization header (“Bearer “). The docs and spec tools work fine. Every execute-request call, e.g. GET /v2/whoami and GET /v2/companies, returns HTTP 403 with a Cloudflare “Just a moment…” managed challenge page from api.7shifts.com instead of an API response. The block has persisted for 20+ minutes. Could you check whether the MCP server’s outbound requests to the API are being challenged by Cloudflare?
