Provider guidance

  • This is Upwork's newly launched official Streamable HTTP server, not the stale third-party api.upwork.com/mcp/sse listing.
  • Consequential actions such as proposals, job posts, and offers follow a draft-and-confirm flow and require explicit user confirmation before submission.
  • Authorization could not be started in the 2026-08-24 audit: the advertised CIMD client was not found or disabled, and Dynamic Client Registration returned HTTP 400 invalid_redirect_uri for https://mcptest.io/oauth/callback. This is a provider callback/client-identity incompatibility for a remote web client, not a localhost installation prerequisite.
