Install — Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "cortex402": {
      "command": "npx",
      "args": ["-y", "cortex402-mcp"],
      "env": {
        "CORTEX402_WALLET_PRIVATE_KEY": "0x..."
      }
    }
  }
}

Restart Claude Desktop. The three CorteX402 tools become available to Claude.

Install — Claude Code

claude mcp add cortex402 -- npx -y cortex402-mcp

Then set the env var in your shell or in the config file produced.

Wallet setup

You need a wallet with USDC on Base mainnet (NOT Base Sepolia, NOT Ethereum mainnet). The wallet's private key goes in the CORTEX402_WALLET_PRIVATE_KEY env var.

Easiest funding path:

  1. Coinbase Wallet (self-custody app, not the exchange) → Buy crypto → USDC on Base network → debit card

  2. ~$5 USDC gives ~50 sanctions checks or ~50 aviation queries

  3. Export the private key from Coinbase Wallet (Settings → Show recovery phrase → derive key)

Or use any existing Base mainnet wallet that you control the private key for.

What happens per call

  1. Claude decides one of the CorteX402 tools is relevant to your question

  2. The MCP server constructs the request and calls the corresponding cortex402.vercel.app endpoint

  3. The endpoint returns HTTP 402 with payment requirements

  4. The MCP server signs an EIP-3009 USDC transfer authorization with your wallet

  5. Coinbase's CDP-authenticated facilitator settles the transfer on Base mainnet

  6. The endpoint returns the data + an on-chain transaction hash receipt

  7. Claude formats and returns the data to you

Total time per call: ~3–4 seconds end-to-end. No accounts, no API keys, no monthly minimums.

Security

  • Your private key is stored in your MCP client config and read via env var by this MCP server. The server never logs or transmits it.

  • All payments happen wallet-to-wallet on Base mainnet. No platform takes a cut.

  • Each successful call returns a Base mainnet transaction hash, permanently auditable.

Endpoints + receiving wallets (canonical)

  • Sanctions: 0x8A74c239DeDc0bB9Ee68eAEeC168Cca985f82F58

    A4.3/5.0

    Scored across 7 tools

    Disambiguation5/5

    Each tool targets a completely distinct domain (authentication, aviation weather, mortgage rates, property, sanctions, blockchain balance), with no overlapping functionality. An agent can easily distinguish them based on purpose.

    Naming Consistency5/5

    All tool names follow a consistent pattern of lowercase words separated by underscores, typically combining two nouns (e.g., 'agent_session', 'aviation_weather', 'mortgage_rates'). There is no mixing of styles or irregular verbs.

    Tool Count4/5

    With 7 tools, the count is within the reasonable range for a tool set. However, the broad scope covering multiple unrelated domains makes the number feel slightly more than if the server had a focused purpose.

    Completeness2/5

    The set lacks any coherent domain; each tool is a standalone call. For the implied purpose of a versatile data API, many common data needs are missing (e.g., stock prices, company info). Within each sub-domain, the coverage is minimal—typically just one operation per type.
