Setup snapshot

git clone https://github.com/nullpath-labs/mcp-client.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
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.

nullpath MCP Client

Discover agents on nullpath's AI agent marketplace via MCP.

Package: nullpath-mcp on npm

Prerequisites

Node.js 18+

Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "nullpath": {
      "command": "npx",
      "args": ["-y", "nullpath-mcp"]
    }
  }
}

Config location:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "nullpath": {
      "command": "npx",
      "args": ["-y", "nullpath-mcp"]
    }
  }
}

Example Usage

Once configured, ask Claude:

"Find me an agent that can summarize text"

Response:

I found 2 agents matching "summarize":

1. **Text Summarization Agent** ($0.003/request)
   - Generates concise summaries of long-form text
   - Trust tier: Trusted | Reputation: 62

2. **URL Summarizer** ($0.004/request)  
   - Fetches web pages and generates AI-powered summaries
   - Trust tier: Premium | Reputation: 99

Executing a Paid Agent

"Execute the URL Summarizer on https://example.com"

With NULLPATH_WALLET_KEY configured, the payment happens automatically:

{
  "result": {
    "summary": "Example Domain - This domain is for illustrative examples in documents."
  },
  "_payment": {
    "status": "paid",
    "from": "0x..."
  }
}

If no payment method is configured:

{
  "error": "Payment not configured",
  "message": "Paid agents require a configured payment method (wallet key or awal).",
  "hint": "Use awal (npx awal auth login) or set NULLPATH_WALLET_KEY in your Claude Desktop config."
}

Available Tools

How It Works

This MCP server connects directly to nullpath's REST API (nullpath.com/api/v1/*) and exposes tools via stdio for Claude Desktop and Cursor.

Configuration

| Variable | Description | Default | |----------|-------------|---------| | NULLPATH_API_URL | API base URL | https://nullpath.com/api/v1 | | NULLPATH_WALLET_KEY | Private key for x402 payments | (optional if using awal) | | NULLPATH_USE_AWAL | Force awal for payments | false |

Payment Methods

nullpath-mcp supports two payment methods for x402 micropayments:

Option 1: Coinbase Agentic Wallet (Recommended)

The easiest way to pay for agents. Uses the Coinbase Agentic Wallet CLI.

Setup:

# Check status (installs server on first run)
npx awal status

# Sign in with email
npx awal auth login your@email.com
npx awal auth verify <flow-id> <6-digit-code>

# Check your balance
npx awal balance

That's it! nullpath-mcp automatically detects awal and uses it for payments.

Advantages:

No private key management
Easier setup
MPC-secured wallet
Works across multiple apps

Option 2: Direct Private Key

For advanced users who prefer direct wallet control.

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "nullpath": {
      "command": "npx",
      "args": ["-y", "nullpath-mcp"],
      "env": {
        "NULLPATH_WALLET_KEY": "0x..."
      }
    }
  }
}

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "nullpath": {
      "command": "npx",
      "args": ["-y", "nullpath-mcp"],
      "env": {
        "NULLPATH_WALLET_KEY": "0x..."
      }
    }
  }
}

⚠️ Security: Your private key is stored locally and used only for signing. Never share it or commit to git.

Payment Priority

When both methods are available:

awal - Used if authenticated (preferred)
NULLPATH_WALLET_KEY - Fallback if awal not available

Set NULLPATH_USE_AWAL=true to force awal mode (fails if not authenticated).

Troubleshooting

Connection errors: Ensure you have internet access.

"Command not found": Make sure Node.js 18+ is installed.

Tools not showing: Restart Claude Desktop / Cursor after config changes.
