I'm sorry you're encountering the error "failed to list tools from MCP server MCPServerHTTP." This can happen for a few different reasons, and I’m here to help you understand them so we can get this sorted out together: • Server Initialization Failure: The MCP server needs to be up and running before tools can be listed. Sometimes connection issues, authentication hiccups, or the server being unavailable might cause this. • Network or Connection Issues: Double-checking the URLs, firewall settings, or if the server is temporarily down can often reveal the root cause. • Timeout Configuration: If the timeout settings are too short, the server might not have enough time to respond, leading to this error. • Improper Client Initialization: Ensuring that the client is correctly initialized is important to avoid this problem. • Transport Protocol Issues: Sometimes the chosen transport method, like SSE or streamable HTTP, might run into issues that cause failures. • Server-Side Errors: There could be issues with how the MCP server’s tools are registered or configured, which might affect the response. To help you troubleshoot, I recommend confirming that the MCP server URL is accurate and reachable, checking your network connection, making sure the server is running smoothly and configured correctly, and if you notice any network delays, try increasing the timeout values.
