The Check MCP URLs workflow (after the connection-failure probe fix in this PR's parent) surfaced four endpoints that fail every connection: - mcp.deepsense.ai does not resolve in DNS at all. The biorxiv, chembl, and clinical_trials servers were rehosted under hcls.mcp.claude.com (Anthropic MCP directory entries dated 2026-01-07). Paths are unchanged; only the host moved. All three return a complete MCP initialize response with no auth. - mcp.paypal.com/mcp returns 404 at every path. PayPal's live endpoint is /sse (SSE transport, not streamable HTTP) and returns 401 with WWW-Authenticate: Bearer realm="OAuth" — alive, OAuth required. Their docs claim /http for streamable transport but it returns 404 today. Type changed http -> sse to match the actual transport. Anyone with the bio-research or small-business bundle installed gets connect failures on every agent spawn until this lands.

/sseandtype: sse./mcpand/httpboth return 404. PayPal's MCP quickstart documents/httpas the streamable endpoint but it doesn't respond as of today./ssereturns 401 with OAuth challenge headers and the authorization-server metadata is live, so the SSE transport works end-to-end. Type changedhttp→sseto match. If PayPal stands up the streamable endpoint later, that's a one-line follow-up.Check MCP URLsshould go fully green onmainafter this lands.
