This project is a USPTO patent data access server based on FastMCP. It supports accessing patent and patent application data from the United States Patent and Trademark Office through the Patent Public Search API and the Open Data Portal API, providing patent search, full - text retrieval, PDF download, and metadata query functions for MCP clients such as Claude Desktop.
