Prices are paid in USDC on Base, per request, by the wallet you configure. The three free sample tools work without any wallet.

Install

One-click (Claude Desktop): download brazilayer-mcp.mcpb from the latest release and open it — Claude Desktop installs the server and prompts for your wallet key (optional).

From source:

git clone https://github.com/brazilayer/mcp brazilayer-mcp
cd brazilayer-mcp && npm install

Claude Code:

claude mcp add brazilayer -e BRAZILAYER_PRIVATE_KEY=0xYOUR_KEY -- npx tsx /path/to/brazilayer-mcp/servidor.ts

Claude Desktop / Cursor (mcpServers config):

{
  "mcpServers": {
    "brazilayer": {
      "command": "npx",
      "args": ["tsx", "/path/to/brazilayer-mcp/servidor.ts"],
      "env": { "BRAZILAYER_PRIVATE_KEY": "0xYOUR_KEY" }
    }
  }
}

Configuration

Variable

Purpose

BRAZILAYER_PRIVATE_KEY

Private key (0x…) of the wallet that pays for calls. Needs USDC on Base. Without it, only the free sample tools work.

BRAZILAYER_API_URL

API base URL. Default: https://api.brazilayer.com

⚠️ Wallet safety: the key you configure signs real payments. Use a dedicated wallet holding only a small budget (a few dollars covers hundreds of calls), never your main wallet.

How payment works

Each paid tool calls the Brazilayer API. The server replies HTTP 402 with the price and payment terms; this MCP server signs a USDC authorization (EIP-3009, gasless for you) and retries automatically. One tool call ≈ two seconds, end to end. The service is also listed on the x402 Bazaar for autonomous discovery.
