@patentprecheck/mcp — Patent PreCheck CLI + MCP server
Run a patentability pre-check on your code from inside your terminal or your AI coding agent (Cursor, Claude Code, Codex, Antigravity). It wraps the hosted Patent PreCheck engine, so no API keys are required — the scoring engine and prior-art corpus stay server-side.
Informational only — not legal advice and not a substitute for a licensed patent attorney.
What it does
- Scores code or an invention description across the four USPTO statutory pillars (§101 eligibility, §102 novelty, §103 non-obviousness, §101 utility) plus a separate §112 filing-readiness signal.
- Reports the band (Not Ready → File Ready), the pillar holding the band back, top opportunities to strengthen, and how much prior art was consulted.
- Exposes MCP tools so an agent can score the code it just wrote, inline.
