Setup snapshot

git clone https://github.com/KasarLabs/cairo-coder-mcp.git
  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Cairo Coder MCP Server

A Model Context Protocol (MCP) server for Cairo and Starknet development assistance via the Cairo Coder API.

⚠️ Repository Moved / Deprecated

This project now lives in the Ask Starknet monorepo

The npm package remains published here

This repo will not receive further updates.

Quick Start

Install via Claude Code

# Install Cairo Coder MCP
claude mcp add cairo-coder -e CAIRO_CODER_API_KEY=YOUR-API-KEY-HERE -- npx -y @kasarlabs/cairo-coder-mcp

Note: Replace YOUR-API-KEY-HERE with your actual API key from cairo-coder.com

Manual Usage

Use this MCP server directly with npx:

npx -y @kasarlabs/cairo-coder-mcp

Configuration

The server supports two modes of operation:

Mode 1: Public Cairo Coder API (Default)

Use the official Cairo Coder API with your API key.

Environment Variables:

  • CAIRO_CODER_API_KEY: Your Cairo Coder API key (required)

MCP Client Setup:

{
  "mcpServers": {
    "cairo-coder": {
      "command": "npx",
      "args": ["-y", "@kasarlabs/cairo-coder-mcp"],
      "env": {
        "CAIRO_CODER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Mode 2: Local/Custom Endpoint

Use a local or custom Cairo Coder API endpoint (no API key required).

Environment Variables:

  • CAIRO_CODER_API_ENDPOINT: Your local endpoint URL (e.g., "http://localhost:8000")

MCP Client Setup:

{
  "mcpServers": {
    "cairo-coder": {
      "command": "npx",
      "args": ["-y", "@kasarlabs/cairo-coder-mcp"],
      "env": {
        "CAIRO_CODER_API_ENDPOINT": "http://localhost:8000"
      }
    }
  }
}

Note: When using CAIRO_CODER_API_ENDPOINT, the server automatically switches to local mode and no API key is required or used.

Available Tools

assist_with_cairo

Get help with Cairo and Starknet development tasks.

Parameters:

  • query (string, required): Your Cairo/Starknet development question
  • context (string, optional): Additional context or code snippets

Examples:

// Simple request
{
  "query": "Write a simple Cairo contract that implements a counter"
}

// With context
{
  "query": "How can I optimize this contract?",
  "context": "#[starknet::contract]\nmod Counter {\n    // existing code here\n}"
}

What You Can Do

  • Write Cairo code: Generate smart contracts and Cairo code
  • Refactor code: Improve and optimize existing code
  • Implement features: Complete TODOs and implement specific functionality
  • Learn Starknet: Get contextual information about the Starknet ecosystem
  • Best practices: Receive advice based on Cairo/Starknet documentation

Tips for Better Results

  • Use specific queries (e.g., "Using OpenZeppelin to build an ERC20" instead of just "ERC20")
  • Include relevant code snippets when working with existing code
  • Provide necessary context for more accurate responses

Development

Prerequisites

  • Node.js >= 18
