What external tool is required for this skill?

This skill requires 'mcptools' to be installed on your system. You can install it via Homebrew using 'brew tap f/mcptools && brew install mcp' or via Go.

How do I handle MCP servers that use the gateway pattern?

The skill includes specific command patterns to call a primary tool with an 'action' parameter, which is common in gateway-style MCP implementations.

Does it provide a visual interface?

Yes, by using the 'mcp web' command, the skill can launch a visual debugging interface in your browser for a more intuitive exploration of MCP capabilities.

What is the primary use of the mcp-debug skill?

It is used to test and diagnose issues with MCP (Model Context Protocol) servers, allowing you to call tools and see raw responses directly without needing a full application integration.

Can I use this with local and remote MCP servers?

Yes, it supports local servers via file paths/configs and local URLs, as well as remote servers using HTTP headers for Bearer token authentication.

API Development

Debugs and tests Model Context Protocol (MCP) servers by calling tools directly and inspecting raw JSON responses in real-time.

The mcp-debug skill empowers developers to diagnose, explore, and verify Model Context Protocol (MCP) servers directly within the Claude Code environment. By leveraging the mcptools utility, it allows for listing available tools, executing specific tool calls with custom parameters, and opening interactive shells or web interfaces for visual debugging. This skill is essential for developers building or integrating custom MCP servers, helping them identify authorization issues, malformed responses, or connectivity problems across different configuration sources including Claude Desktop and custom URLs.

Key Features

01Tool discovery and capability exploration for any MCP server

02Support for multiple configuration sources and authentication headers

03Raw response inspection and output formatting for complex gateway patterns

04Direct execution of MCP tools with custom JSON parameters

0516 GitHub stars

06Interactive shell and web-based visual debugging interfaces

Use Cases

01Verifying MCP server connectivity and authentication during local development

02Exploring the operations and required parameters of a new or unfamiliar MCP server

03Debugging unexpected or empty data returns from specific MCP tool actions
