Bazaar

You can run the Bazaar MCP Server to access AI-powered tools through x402 micropayments. This server lets you perform tasks like AI analysis, screenshots, document conversions, and security checks directly from compatible MCP clients. It supports paid endpoints via the x402 protocol and can operate in SSE mode for remote connections.

How to use

Start the server in SSE mode to enable real-time client connections, then connect your MCP client to the provided SSE endpoint to access paid and free tools. Use your MCP client to invoke the available tools, manage payments, and view results within your workflow.

How to install

Prerequisites: ensure you have Node.js installed on your system. You do not need Python or other runtimes for basic usage.

# Install the Bazaar MCP Server globally
npm install -g @opspawn/bazaar-mcp

# Or run directly without installation
npx @opspawn/bazaar-mcp

Configuration

Configure your MCP client to connect to the Bazaar MCP Server as described in your client’s setup. The server supports a dedicated SSE transport for remote access and uses environment variables to control payment and connectivity.

Environment and payments

Use the x402 micropayment system for paid endpoints. You will receive a detailed 402 response when you attempt to call a paid tool without a payment token, showing price and payment options. Supported networks include Base, SKALE Europa, and Arbitrum One.

Additional notes
