MCP server to interact with the Cairo Coder API
npm install @kasarlabs/cairo-coder-mcp
A Model Context Protocol (MCP) server for Cairo and Starknet development assistance via the Cairo Coder API.
Use this MCP server directly with npx:
``bash`
npx -y @kasarlabs/cairo-coder-mcp
The server supports two modes of operation:
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:
`json`
{
"mcpServers": {
"cairo-coder": {
"command": "npx",
"args": ["-y", "@kasarlabs/cairo-coder-mcp"],
"env": {
"CAIRO_CODER_API_KEY": "your-api-key-here"
}
}
}
}
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:
`json`
{
"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.
Get AI-powered assistance with Cairo and Starknet development tasks.
Parameters:
- query (string, required): Your Cairo/Starknet development questioncontext
- (string, optional): Additional context or code snippets
Examples:
`typescript
// 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}"
}
`
- Write Cairo code: Generate smart contracts and Cairo code
- Refactor code: Improve and optimize existing code
- Implement features: Complete TODOs and implement specific functionality
- Debug issues: Get help troubleshooting Cairo compilation and runtime errors
- Best practices: Receive advice based on Cairo/Starknet documentation
> Note: For general Starknet ecosystem knowledge and protocol information, use the @kasarlabs/starknet-knowledge-mcp server instead.
- 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
