MCP Configuration

What problem does it solve?

Setting up and managing Micro-Agent Communication Protocol (MCP) server configurations, especially across different environments and tools, can be complex and error-prone. This skill simplifies the entire configuration lifecycle.

Core Features & Use Cases

• Centralized Registry Management: Provides scripts to initialize, add, list, and scan MCP servers in a universal registry (~/.claude/mcp-registry/servers.json), ensuring consistent access.
• Multi-Tool Transformation: Transforms MCP server definitions from the central registry into formats compatible with various tools like Claude Code (.mcp.json), Codex (config.toml), Gemini, and VS Code (.vscode/mcp.json).
• Environment & Security Setup: Helps configure environment variables, manage API keys securely in .env files, and validate configuration for correctness.
• Permission Management: Includes scripts to update and validate slash command permissions in .claude/settings.local.json, ensuring proper access control.
• Use Case: A developer needs to integrate a new FastMCP server with their local Claude Code environment and also make it available for Codex. This skill can initialize a global MCP registry, add the server, and then transform its configuration into the specific .mcp.json and config.toml formats required by each tool.

Quick Start

Initialize the global MCP server registry, then scan the '/Projects/Mcp-Servers' directory for existing MCP servers and add them to the registry.
