How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security25
- Malware scan not yet available for this package.Unverified
- CVE check failed: an unpatched critical CVE affects this package; the score is capped at 0. See how to fix → View diagnostics → Fail
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 8 of 73 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to jonnybottles/patch-tuesday-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 101 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability71
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 4460 tokens (~4460/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management70
- Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
msrc_search Search Microsoft Security Updates ~3,985
Search Microsoft security updates (Patch Tuesday) from the official MSRC API. Combines keyword search, CVE/KB lookup, and product/severity/exploitation filtering into a single flexible tool. All filter parameters are optional and can be combined. When no filters are provided, returns the most urgent vulnerabilities from the most recent *released* Patch Tuesday (CISA-KEV- listed or exploited first, then by EPSS exploitation probability, severity, and CVSS score). The upcoming month's document exists before its Patch Tuesday but only holds early Chromium/third-party and out-of-band entries; it is skipped by default and served only when requested via month=. Results are enriched with EPSS scores (FIRST.org daily exploit prediction, 0-1) and CISA KEV (Known Exploited Vulnerabilities) catalog data when available. Use this tool to: - Get the latest Patch Tuesday overview (include_stats=True, limit=0) - Browse the most urgent fixes this month (no filters) - Look up a specific CVE with full detail (cve="CVE-2026-41108") -- works across all months, returns KBs, affected products, CVSS, description, FAQs, EPSS score, and KEV status - Find which CVEs a KB article fixes (kb="5094123" or kb="KB5094123") -- scans recent months, or a specific month when combined with month= - Look up many KBs in one call (kb=["5094123", "KB5094127", ...], up to 30) -- e.g. a machine's installed-update list; returns one grouped per-KB result entry each, with per-KB found/not-found status - Check whether a KB has been superseded by newer patches (kb="5087538", include_chain=True) -- walks Microsoft-stated supersedence links - See what Microsoft has confirmed an update breaks (kb=..., include_known_issues=True) -- known issues from the KB's public support page: symptoms, workarounds, and the resolving update when stated - See what an update changes (kb=..., include_update_summary=True) -- the KB support page's summary and improvements highlights, beyond the security fixes alrea…
