MCP Server Creator Skill
Automated tool for creating production-ready Model Context Protocol (MCP) servers with TypeScript or Python SDKs.
What This Skill Does
The MCP Server Creator skill streamlines the entire process of building MCP servers by:
- Gathering requirements through interactive questions about your server's purpose
- Selecting the right SDK (TypeScript, Python, Java, Kotlin, or C#)
- Generating project structure with proper dependencies and build configuration
- Creating server implementation with tools, resources, and prompts
- Configuring Claude Desktop integration with proper paths and environment
- Providing testing guidance with MCP Inspector and validation steps
When to Use
Use this skill when you want to:
- Connect Claude to your data sources (databases, APIs, files)
- Expose custom tools for AI to call
- Build workflow automation servers
- Create enterprise integrations
- Learn MCP development patterns
Trigger Phrases
- "create an MCP server for [purpose]"
- "build a Model Context Protocol server"
- "set up MCP integration with [data source]"
- "help me create a server for Claude Desktop"
- "scaffold an MCP server"

Example Usage
Simple Tool Server
You: "Create an MCP server that can search my local documents"
Skill generates:
- File search tool with glob patterns
- Content search tool using grep
- Resource handlers for file contents
- Claude Desktop configuration
- Security validations (path traversal prevention)
Database Integration
You: "Build an MCP server to query my PostgreSQL database"
Skill generates:
- Database query tool with SQL validation
- Schema inspection tools
- Connection pooling setup
- Environment variable configuration
- Read-only query enforcement
API Wrapper
You: "Create a server that wraps the GitHub API"
Skill generates:
- GitHub API client setup
- Tools for common operations (search, issues, PRs)
- Authentication configuration
- Rate limiting handling
- Response formatting for AI consumption
Supported Languages
| Language | SDK | Best For |
|---|---|---|
| TypeScript | @modelcontextprotocol/sdk |
Web APIs, JS ecosystem |
| Python | mcp[cli] (FastMCP) |
Data processing, ML |
| Java | Spring AI MCP | Enterprise Java apps |
| Kotlin | Kotlin SDK | Android/JVM apps |
| C# | ModelContextProtocol NuGet | Windows/Azure apps |
Common Patterns Included
The skill includes templates and guidance for:
- Database Integration: PostgreSQL, MySQL, MongoDB
- API Wrappers: REST APIs, GraphQL
- File System Access: Secure file operations
- Search Integration: Elasticsearch, vector search
- Workflow Automation: CI/CD, deployments
- Notification Systems: Email, Slack, SMS
- Data Processing: ETL, analytics pipelines
- Authentication: Token validation, permissions
Testing Your Server
The skill provides three testing approaches:
-
MCP Inspector (recommended first)
npx @modelcontextprotocol/inspector node build/index.js- Browser-based testing interface
- Validates schemas and responses
- No Claude Desktop required
-
Claude Desktop Integration
- Add to
claude_desktop_config.json - Restart Claude Desktop
- Test with natural language
- Add to
-
Custom Client
- Build your own MCP client
- Use in other AI applications

Security Features
Every generated server includes:
- ✅ Environment variable management (never commit secrets)
- ✅ Input validation with schemas
- ✅ Proper error handling (don't leak internals)
- ✅ .gitignore configuration
- ✅ Logging best practices (stderr only for STDIO)
- ✅ Path traversal prevention (file servers)
- ✅ SQL injection prevention (database servers)
Next Steps After Generation
- Review generated code and customize tool implementations
- Add your API keys/credentials to
.env - Build the project (
npm run buildfor TypeScript) - Test with MCP Inspector
- Add to Claude Desktop configuration
- Test with natural language queries
- Iterate and enhance based on usage
Troubleshooting
The skill includes debugging guidance for:
- Server not detected in Claude Desktop
- Tools not appearing
- Connection timeouts
- Build errors
- STDIO logging issues
- Configuration syntax errors
