MCP Troubleshooter

MCP Troubleshooter [Work in Progress]

⚠️ IMPORTANT: This package is currently under development and not yet ready for production use. The current version is a work in progress and may contain incomplete features or breaking changes.

A self-diagnostic framework for AI models that enables them to diagnose and fix MCP-related issues.

Architecture

Overview

MCP Troubleshooter is a specialized MCP server that transforms troubleshooting from a developer-only task into a capability the AI itself can leverage, allowing AI models to:

Analyze MCP logs - Automatically scan for common error patterns and provide insightful diagnostics
Validate configurations - Check server configurations against best practices and identify issues
Test connections - Verify network connectivity and server availability
Generate templates - Create working MCP server configurations for quick setup
Fix common issues - Update configurations and implement solutions directly

Installation

# Install the package globally
npm install -g @devlimelabs/mcp-troubleshooter

# Start the server
mcp-troubleshooter

Usage

Example Use Cases

Diagnosing a Broken MCP Server

User: My MCP server isn't connecting properly to Claude Desktop. Can you help diagnose it?

Claude: I'll help diagnose your MCP server connection issue. First, let me run some diagnostics.

[Uses check-mcp-server-process tool with the command from the user]

I've identified several possible issues with your MCP server:

1. **Connection Timeout**: The server isn't responding within the expected timeframe.
2. **JSON-RPC Format Error**: There seems to be a format issue in the JSON-RPC responses.
3. **Transport Mismatch**: Claude Desktop is expecting stdio transport, but your server might be using SSE.

Let me run a more specific connection test to confirm:

[Uses test-port-availability tool]

The connection test confirms that your server is starting, but it's timing out during the handshake phase. This is likely due to incorrect JSON-RPC message formatting in your server implementation.

Recommended fixes:
1. Ensure your server returns properly formatted JSON-RPC 2.0 responses
2. Check your transport implementation, it should be using proper stdio pipes
3. Verify that your server is correctly handling the initialize method

Would you like me to analyze a specific log file or check your server's code for these issues?

Validating MCP Configuration

User: Can you validate my Claude Desktop MCP configuration?

Claude: I'd be happy to validate your Claude Desktop MCP configuration.

[Uses read-mcp-config tool]

I've analyzed your Claude Desktop configuration file. Here are my findings:

✅ **Valid Configuration Structure**: The overall structure of your configuration is valid.

⚠️ **Path Issues**: 2 servers have invalid paths:
- "code-llm": The file path "/usr/local/bin/code-llm" doesn't exist
- "database-tool": The command "db-tool" is not in the PATH

❌ **Environment Variables**: 1 server has missing required environment variables:
- "firebase-mcp": Missing required FIREBASE_API_KEY

✅ **Transport Configuration**: All servers properly specify transport options

Recommended fixes:
1. Update the path for "code-llm" to the correct location
2. Install "db-tool" or correct its path
3. Add the missing FIREBASE_API_KEY to the "firebase-mcp" server configuration

Would you like me to help you implement any of these fixes?
