MCP Dev Toolkit

Scaffold and build MCP (Model Context Protocol) servers with common developer tools.

Quick Start

Scaffold a new MCP server:

npx @anthropic/mcp-cli create my-server

Or use the scaffold script for a batteries-included setup:

bash scripts/scaffold.sh my-server python   # Python MCP server
bash scripts/scaffold.sh my-server typescript  # TS MCP server

Architecture

An MCP server exposes tools that LLMs can call. Each tool has:

• name: Tool identifier
• description: What the tool does (LLM reads this to decide when to use it)
• inputSchema: JSON Schema for parameters

Tool Patterns

Database Access

See references/database-tools.md for PostgreSQL, SQLite, and MongoDB tool patterns.

File Management

See references/file-tools.md for read, write, search, and transform tools.

API Integration

See references/api-tools.md for REST/GraphQL wrapping patterns.

Transport Types

• stdio: Local CLI integration (default for Claude Desktop)
• HTTP/SSE: Remote server (for shared/team deployments)
• Streamable HTTP: Modern transport (MCP spec 2025-03)

Testing

Test tools locally before deploying:

npx @anthropic/mcp-cli inspect ./my-server

Publishing

Publish to npm (TypeScript) or PyPI (Python), then configure in MCP clients.
