Toreador Server

Official Model Context Protocol server for Toreador. Lets Claude Desktop, Cursor, and any other MCP-capable assistant generate crypto QR codes and manage payment sessions on your behalf.

⚠️ Requires a Pro plan API key (tdr_...) from your Toreador dashboard. The MCP server runs locally and uses your key to call https://toreador.io/api/v1/public.

Tools exposed

Tool	What it does
toreador_generate_qr	Generate a QR code for native tokens (BTC, ETH, SOL, POL) or Solana SPL (USDC on Solana). Returns the on-chain payment URI and a base64 PNG data URI.
toreador_create_session	Create a hosted payment session for ERC-20 stablecoins (USDC, USDT, EURC) on Ethereum, Polygon or Base. Returns a session ID, security code and a hosted payment URL.
toreador_get_payment_status	Poll the status of an ERC-20 payment session: pending / submitted / confirming / completed / expired / failed.
toreador_list_history	List the 50 most recent QR code generations.
toreador_list_sessions	List the 50 most recent ERC-20 payment sessions.

Install in Claude Desktop

Edit Claude Desktop's config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Add the toreador entry under mcpServers:

{
  "mcpServers": {
    "toreador": {
      "command": "npx",
      "args": ["-y", "@toreador/mcp-server"],
      "env": {
        "TOREADOR_API_KEY": "tdr_your_key_here"
      }
    }
  }
}

Restart Claude Desktop. You should see the 5 Toreador tools in the tools menu.

Install in Cursor

In Cursor settings → MCP → "Add new MCP server", paste:

{
  "command": "npx",
  "args": ["-y", "@toreador/mcp-server"],
  "env": { "TOREADOR_API_KEY": "tdr_..." }
}

Example prompts

Once installed, try these prompts in your MCP client:

• "Generate a Bitcoin QR code for 0.001 BTC to bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh."
• "Create a USDC payment session for 50 USDC on Polygon to 0x742d35Cc6634C0532925a3b844Bc9e7595f2bD18."
• "What's the status of session ses_123?"
• "Show me my last 10 payment sessions."

The assistant will pick the right tool, call Toreador, and return the result — including the QR code data URI which most clients can render inline.

Configuration

Environment variable	Default	Description
TOREADOR_API_KEY	required	Your Pro plan API key. Format: tdr_....
TOREADOR_BASE_URL	https://toreador.io/api/v1/public	Override the API base URL (useful for testing).
TOREADOR_TIMEOUT_MS	30000	Per-request timeout in milliseconds.

Trust and safety

• Local only. The MCP server runs on your machine via stdio. Your API key never leaves your computer except in outbound HTTPS calls to toreador.io.
• Non-custodial. Toreador never holds funds. The MCP tools only generate QR codes and read session state — they cannot move money.
• Read or create, no destruction. Tools either generate new payment objects or read existing ones. There is no "delete" or "refund" tool.

Build from source

git clone https://github.com/Bentonabento/toreador-sdk.git
cd toreador-sdk/mcp
npm install
npm run build
TOREADOR_API_KEY=tdr_... node dist/index.js

The server will boot, print [toreador-mcp] ready (5 tools registered) to stderr, and wait for MCP requests on stdin.
