Model Context Protocol

MCP Documentation

CardSight's Model Context Protocol (MCP) server exposes our complete trading card catalog and identification capabilities directly to AI assistants like Claude and ChatGPT. Enable your users to ask natural language questions about cards—"Which Bo Jackson rookie cards were released in 1990?"—and get instant, accurate answers powered by our 14M+ trading card database.

Unlike our REST API which is designed for developers building applications, the MCP server is designed for end-user experiences. Integrate it into your app to give users an AI-powered conversational interface for card search, identification, pricing, and catalog browsing. This documentation covers the available MCP tools, request/response formats, and integration guides for Claude Desktop and other MCP-compatible AI assistants.
