Patentability pre-check for code — USPTO pillar scores, filing-readiness, and prior-art signals.

A critical issue was found. Do not connect this server as-is.
Scanned 1 month ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The patent-precheck MCP server exposes 12 tools, focused primarily on general-purpose capabilities. Its published description reads: "Patentability pre-check for code — USPTO pillar scores, filing-readiness, and prior-art signals". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates patent-precheck F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Cross-tool shadowing" and "Cross-tool shadowing". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check patent-precheck's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
