## Tools (as reported by the server, not verified)

- `precheck\_score`: Run a prior-art density / risk-profile pre-check on source code or an invention description. Returns a 0–100 directional score across the four USPTO statutory pillars \(§101 eligibility, §102 novelty, §103 non-obviousness, §101 utility\), a separate §112 filing-readiness signal, the band \(Not Ready →
- `precheck\_prior\_art`: Return the closest prior-art matches consulted for an invention \(titles, sources, similarity scores, URLs\). Runs the same analyze pipeline as precheck\_score but focuses on retrieval results. Pass invention text via \`code\`.
- `precheck\_rejection\_patterns`: Preview examination-risk signals: similar office-action rejections, abandonment patterns, and the primary statutory basis an examiner might cite \(§101/§102/§103\). Use after precheck\_score to explain prosecution risk.
- `precheck\_legal\_context`: Return a short snippet of current US software-patent legal guidance \(CAFC, USPTO, Alice/§101\) relevant to scoring this invention. Informational only — not legal advice.
- `precheck\_pillars`: List the five scoring pillars \(with statutes and weights\) and the band rules used by precheck\_score. Use this to explain a score to the user. No network call.
- `precheck\_start\_review`: Return the URL where the user can start a paid \(or promo-unlocked\) Interactive Code Review that strengthens each pillar with evidence and produces a filing package. Use after precheck\_score when the user wants to act on the result.
- `precheck\_search\_corpus`: Fast semantic search against the 2,200,000+ prior-art corpus without LLM scoring. Returns ranked matches with similarity scores. Cheaper than precheck\_score when you only need references.
- `precheck\_cpc\_suggest`: Suggest Cooperative Patent Classification \(CPC\) codes for an invention description. Offline heuristic — informational only. No network call.
- `precheck\_session\_status`: Return status for an active Interactive Code Review session. Requires report\_id and session\_key from the user access email link.
- `precheck\_deliverables`: Return download URLs for finalized ICR deliverables \(filing packet, coaching report, package zip, scorecard PDF\). Requires report\_id and session\_key.
- `precheck\_lookup\_patent`: Resolve a US patent or application number \(e.g. US1234567B2\) via USPTO Open Data Portal and optionally join the indexed prior-art corpus. Returns title, status, CPC, grant-text excerpt, and a public URL. No API key required in the MCP client.
- `precheck\_compare\_to\_patent`: Compare invention text to a known US patent: embedding similarity plus prior-art risk analysis \(statute hints, overlap theme, distinction checklist\). Use when the user names a specific reference patent.
