What it does
CAIRN is a powerful scaffolding tool designed to accelerate the creation of Model Context Protocol (MCP) servers. It removes the boilerplate of setting up new integrations by generating complete, standalone project structures based on user prompts, ensuring that new servers are production-ready and follow best practices from the start.
Tools
- API Integration Generator: Creates a wrapper for external REST APIs as MCP tools (e.g., Slack, Jira).
- Doc Search Generator: Sets up semantic search capabilities over GitHub repositories using Markdown.
- Starter Scaffold: Provides a minimal, working MCP server template for rapid prototyping.
