MCP Builder

Build MCP servers that give Claude tools to call. A tool is a function Claude can invoke: fetch data, create records, send messages, interact with APIs.

Patterns here come from real production servers: gmail-mcp, notion-mcp, photos-mcp, calendar-mcp, iprep-mcp.

See references:

• references/scaffold/ — copy-paste starting point (package.json, tsconfig, src/index.ts)
• references/patterns.md — auth, error handling, pagination, returning data
• references/publishing.md — build, test locally, npm publish workflow
