Exa MCP hosted SSE endpoint (mcp.exa.ai/mcp) down?

  Status: fixed. The outage on 2025-12-17 was caused by an upstream provider issue. A collaborator (Exa maintainer) confirmed on 2025-12-18 that both the regular exa MCP and the websets MCP were fixed and can be used normally again. The thread contains no client-side workaround or configuration change; the resolution was applied on Exa's side.

  As general advice: if a hosted endpoint like https://mcp.exa.ai/mcp (opens external site) ↗ stops responding again, retry it after a short wait or restart/reconnect your MCP client session. During an upstream provider outage the endpoint itself is the problem, so there is nothing to change in your MCP client configuration.
