getting MCP error -32602 while trying to access an mcp-server tool. What does this error code mean / how to fix ?

I don't have specific information about what MCP error -32602 means, but I can suggest some general troubleshooting steps that might help: - Check network configurations to ensure outbound connections are allowed - Verify authentication tokens and credentials are correctly set up - Ensure all necessary headers are properly formatted - Confirm the endpoint URL is correct and accessible Could you share more details about what you were doing when you encountered this error? For example, what specific action were you performing with the mcp-server tool when the error occurred?

MCP error -32602 means you’re sending incorrectly formatted parameters..

Model request failed (attempt #1, reason: (Invalid 'tools[1].function.name': string does not match pattern. Expected a string that matches the pattern '^[a-zA-Z0-9_-]+$'.)) I set up an MCP server, the assistant works fine and does the appropriate tool calls when i use open AI , but it fails with above error when i switch to anthropic claude-sonnet-3.5.
