Mcp Dev Toolkit

Build, test, and deploy MCP (Model Context Protocol) tools for developer workflows. Use when creating MCP servers, adding tool definitions, integrating with databases, file systems, or APIs via MCP. Covers TypeScript and Python MCP server scaffolding, tool registration, transport configuration (stdio, HTTP/SSE), and testing patterns.

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.
