## Tools
- precheck_score (Patent PreCheck — score patentability) - Run a patentability pre-check on source code or an invention description. Returns a 0–100 patentability 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 → File Ready), the pillar that holds the band back, top opportunities to strengthen, and a count of prior-art matches consulted. Pass the text to analyze inline via `code`. Endpoint: https://patentprecheck.com/mcp
- precheck_prior_art (Patent PreCheck — prior art matches) - 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`. Endpoint: https://patentprecheck.com/mcp
- precheck_rejection_patterns (Patent PreCheck — rejection pattern preview) - 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. Endpoint: https://patentprecheck.com/mcp
- precheck_legal_context (Patent PreCheck — legal intelligence 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. Endpoint: https://patentprecheck.com/mcp
- precheck_pillars (Patent PreCheck — scoring reference) - List the five patentability 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. Endpoint: https://patentprecheck.com/mcp
- precheck_start_review (Patent PreCheck — start an Interactive Code 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. Endpoint: https://patentprecheck.com/mcp
- precheck_search_corpus (Patent PreCheck — semantic corpus search) - Fast semantic search against the 1M+ prior-art corpus without LLM scoring. Returns ranked matches with similarity scores. Cheaper than precheck_score when you only need references. Endpoint: https://patentprecheck.com/mcp
- precheck_cpc_suggest (Patent PreCheck — CPC classification hints) - Suggest Cooperative Patent Classification (CPC) codes for an invention description. Offline heuristic — informational only. No network call. Endpoint: https://patentprecheck.com/mcp
- precheck_session_status (Patent PreCheck — ICR session status) - Return status for an active Interactive Code Review session. Requires report_id and session_key from the user access email link. Endpoint: https://patentprecheck.com/mcp
- precheck_deliverables (Patent PreCheck — deliverable download links) - Return download URLs for finalized ICR deliverables (filing packet, coaching report, package zip, scorecard PDF). Requires report_id and session_key. Endpoint: https://patentprecheck.com/mcp
- precheck_lookup_patent (Patent PreCheck — US patent lookup) - 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. Endpoint: https://patentprecheck.com/mcp
- precheck_compare_to_patent (Patent PreCheck — compare invention 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. Endpoint: https://patentprecheck.com/mcp
