Patent Checker MCP

Patent Checker is an MCP server and Agent Skill designed for prior-art exploration in software projects. It fetches public patent data from EPO Open Patent Services and Google Patents to find related patents and report observations. It supports reading codebases, translating features into patent vocabulary, screening candidates, and writing dated reports. It explicitly does not judge infringement or provide legal verdicts.
