What does the skill file contain?
# IMPORTANT: How to Use This Skill This file provides a NAVIGATION GUIDE ONLY. Before implementing any MCP server features, you MUST: 1. Read this overview to understand which reference files are relevant 2. **ALWAYS read the specific reference file(s)** for the features you're implementing 3. Apply the detailed patterns from those files to your implementation **Do NOT rely solely on the quick reference examples in this file** - they are minimal examples only. The reference files contain critical best practices, security considerations, and advanced patterns. --- # MCP Server Best Practic...
Frequently asked questions
How do I determine if I am already in an mcp-use project?
Check the workspace for a package.json that lists mcp-use as a dependency, or look for any .ts file that imports from mcp-use/server.
What is the recommended way to test a tool or widget without the inspector UI?
Use the mcp-use client command line tool to connect to the server and execute subcommands or generate screenshots.
Should I manually create the MCPServer boilerplate?
No. Use the CLI to scaffold projects to ensure correct TypeScript configuration, dev scripts, and inspector integration.
