## Trust

- hygiene: 80
- liveness: 100
- freshness: 65
- provenance: 45
- drivers: +website +reachable +uptime-100% ~updated-124d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 77/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: precheck_score (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); precheck_prior_art (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); precheck_search_corpus (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 2,013 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 98 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: @patentprecheck/mcp@0.4.1 resolved: 98 packages

- tools: 12, about 2,013 tokens to load them all
- tool set hash: dd28d90fc17e348d156475f8a8cf12aa
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Patent-PreCheck/patent-precheck.svg)](https://protogrid.dev/servers/io.github.Patent-PreCheck/patent-precheck)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (12)

- `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.
- `precheck_cpc_suggest`: Suggest Cooperative Patent Classification (CPC) codes for an invention description. Offline heuristic — informational only. No network call.
- `precheck_deliverables`: Return download URLs for finalized ICR deliverables (filing packet, coaching report, package zip, scorecard PDF). Requires report_id and session_key.
- `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_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_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_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_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 → File Ready), the pillar that holds the band back, opportunities to thicken the technical description, and a count of prior-art matches consulted. Show filename + size and get user yes, then pass confirm_upload: true. Pass the text inline via `code`.
- `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_session_status`: Return status for an active Interactive Code Review session. Requires report_id and session_key from the user access email link.
- `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.
