SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the frustration of broken MCP integrations by providing a structured, step-by-step process to diagnose and fix common issues with MCP server connections, tool registration, and tool execution, saving developers hours of manual debugging.

Core Features & Use Cases

  • Configuration Validation: Checks MCP settings files for syntax errors, missing required fields, and incorrect server commands.
  • Connectivity Testing: Verifies MCP servers start correctly, complete the protocol handshake, and respond to requests as expected.
  • Tool Registration & Execution Debugging: Inspects the tool registry, tests individual tool calls, and identifies why tools are missing or failing.
  • Use Case: For example, if your filesystem MCP tools are not appearing in the available tools list, this skill walks you through verifying your config, testing the server manually, and running discovery to pinpoint the root cause.

Quick Start

Use the debug-mcp-integration skill to troubleshoot why your configured MCP server's tools are not showing up in the available tools list.

Frequently Asked Questions about debug-mcp-integration

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
Why does my MCP server fail to start and register tools with my LLM integration?▼

MCP server startup failures often stem from invalid configuration syntax or missing required fields. This skill validates MCP settings, checks server protocol compliance, and inspects the tool registry to identify why server initialization or tool registration fails.

How do I debug MCP tools that are missing from the available tools list?▼

To debug missing MCP tools, you must verify configuration syntax, test the server protocol handshake manually, and run tool discovery. This skill inspects the tool registry state and analyzes runtime logs to pinpoint the root cause of missing tools.

What is the best way to troubleshoot Model Context Protocol tool execution errors?▼

The best way to troubleshoot Model Context Protocol tool execution errors is to inspect the tool registry and analyze runtime logs for error traces. This skill tests individual tool calls to identify why executions return unexpected errors.

How do I validate MCP configuration files for incorrect server commands?▼

Validating MCP configuration files requires checking settings for syntax errors, missing required fields, and incorrect server commands. This skill provides a structured process to verify MCP configuration syntax and test protocol compliance.

Can I test MCP server protocol compliance manually before running tool calls?▼

Yes, you can test MCP server protocol compliance manually. This skill verifies whether servers start correctly, complete the protocol handshake, and respond to requests as expected before testing individual tool calls.

MCP integration not working: what should I check first in my server setup?▼

When MCP integration is not working, first check your configuration files for syntax errors and missing fields. This skill validates MCP settings and tests server initialization to quickly resolve connection failures and tool registration issues.
