@txn-dev/mcp-server

MCP server for txn.dev - let any AI assistant manage agent payments.

Works with Claude Desktop, Cursor, Windsurf, and any MCP-compatible client.

Setup

Add to your MCP client config:

{
  "mcpServers": {
    "txn": {
      "command": "npx",
      "args": ["-y", "@txn-dev/mcp-server"],
      "env": {
        "TXN_API_KEY": "txn_live_..."
      }
    }
  }
}

Get your API key at txn.dev/dashboard/api-keys. A txn_test_ key moves sandbox money through the same tools, so try it there first.

Claude Code, in one line:

claude mcp add txn -e TXN_API_KEY=txn_test_... -- npx -y @txn-dev/mcp-server
