Free

Overview

Free is a Model Context Protocol server that provides read-only access to Market402 x402 index search, operator track records, and PDF price quotes. As an MCP server, it integrates directly into AI assistants as callable tools, letting models query and retrieve data on your behalf.

Free runs as a remote hosted service at https://mart402.com/mcp/free with no authentication required and nothing to install locally. The latest release is v1.0.0.

Free is listed in the File System category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Free for mart402.com, you can claim this listing to verify ownership and keep the information up to date.
