MCP Introduction

The Model Control Protocol (MCP) integration allows you to expose your Pikku functions as tools and resources that AI models can interact with directly.

Overview​

Pikku provides first-class support for MCP, allowing you to:

  • Tools: Expose functions that AI models can call to perform actions
  • Resources: Provide data sources that AI models can read from
  • Prompts: Create template generators for AI interactions

Quick Start​

1. Define MCP Functions​

Create your MCP functions using the specialized function types:

// mcp.functions.ts
import { NotFoundError } from '@pikku/core'
import {
  pikkuMCPPromptFunc,
  pikkuMCPResourceFunc,
  pikkuMCPToolFunc,
} from '../.pikku/pikku-types.gen.js'

// Example tool, resource, and prompt functions...

2. Register MCP Endpoints​

Register your functions as MCP endpoints:

// mcp.routes.ts
import {
  addMCPTool,
  addMCPResource,
  addMCPPrompt,
} from '../.pikku/pikku-types.gen.js'

// Register your functions...

3. Run the MCP Server​

npx pikku serve mcp

Your Pikku functions are now available as MCP tools, resources, and prompts!
