Noir Coder MCP Server

A Model Context Protocol (MCP) server for Noir and zero-knowledge proof development assistance via the Noir Coder API.

Quick Start

Use this MCP server directly with npx:

npx -y @kasarlabs/noir-coder-mcp

Configuration

The server connects to the Noir Coder API endpoint. No API key is required.

MCP Client Setup:

{
  "mcpServers": {
    "noir-coder": {
      "command": "npx",
      "args": ["-y", "@kasarlabs/noir-coder-mcp"]
    }
  }
}

Available Tools

assist_with_noir

Get help with Noir and zero-knowledge proof development tasks.

Parameters:

• query (string, required): Your Noir/zero-knowledge proof development question
• codeSnippets (array of strings, optional): Additional code snippets for context
• history (array of strings, optional): Conversation history for context

Examples:

// Simple request
{
  "query": "Write a simple Noir circuit that proves knowledge of a secret number"
}

// With code snippets
{
  "query": "How can I optimize this circuit?",
  "codeSnippets": ["fn main(private_input: Field, public_input: pub Field) {\n    assert(private_input * private_input == public_input);\n}"]
}

What You Can Do

• Write Noir code: Generate zero-knowledge proof circuits and Noir code
• Refactor code: Improve and optimize existing circuits
• Implement features: Complete TODOs and implement specific functionality
• Learn Noir: Get contextual information about the Noir ecosystem
• Best practices: Receive advice based on Noir/zero-knowledge proof documentation

Tips for Better Results

• Use specific queries (e.g., "Creating a circuit to prove knowledge of a secret" instead of just "Noir circuit")
• Include relevant code snippets when working with existing circuits
• Provide necessary context for more accurate responses
