MCP Troubleshooter

MCP Troubleshooter is an AI-assisted MCP server that helps you diagnose, validate, and fix MCP-related issues. It analyzes logs, checks configurations, tests connections, and can generate working templates to speed up setup and recovery across your MCP ecosystem.

How to use

You use the MCP Troubleshooter with an MCP client to automate common maintenance and debugging tasks. The server can analyze MCP logs to identify error patterns, validate your MCP configurations against best practices, test network connections to MCP endpoints, generate ready-to-use server templates, and apply fixes directly when appropriate. This enables you to reduce manual digging through logs and configurations and focus on resolving the root causes.

Typical usage patterns include running diagnostics against a troubled MCP server, validating your Claude Desktop or other MCP client configurations, and letting the troubleshooter propose or apply safe fixes. You can start by launching the troubleshooter locally, then connect your MCP client to run targeted checks and generate templates for quicker recovery.

How to install

# Prerequisites
# Ensure you have Node.js installed (LTS version recommended) and npm available on your system.
node -v
npm -v

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

# Start the server
mcp-troubleshooter

Notes and tips

• The troubleshooter is designed for development and diagnostic use. Run it in a controlled environment and review any proposed changes before applying them to production MCP servers.

• If you plan to automate checks, you can expose the troubleshooter as a local stdio service and let your MCP client invoke its capabilities through the standard command interface.

Security and best practices

• Do not run the troubleshooter with elevated privileges in production environments unless absolutely necessary and only after validating all changes in a staging environment.

• Maintain backups of configurations and logs before applying any fixes generated by the troubleshooter.

Platform support

Windows: Accesses logs and configs where you install the MCP Troubleshooter. macOS and Linux follow standard system logging and configuration paths for Node.js-based utilities.

Examples and use cases

Diagnosing a broken MCP server and validating Claude Desktop configuration are common tasks. The troubleshooter automatically scans logs, checks transport and protocol compatibility, validates configuration schemas, and can generate a template for a working MCP server setup.

Tools and capabilities

The troubleshooter provides a suite of tools to cover the full troubleshooting lifecycle. You can read MCP logs, analyze them for error patterns, read and validate MCP server configurations, update configurations with backups, validate server transport, test port availability, verify MCP server processes, and generate templates for new MCP servers or Claude Desktop configurations.
