## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-20.

- **Supply Chain Security**: 82/100
  - No malware found by supply-chain analysis.
  - CVE check failed: a known high-severity CVE affects cryptography 48.0.1, a direct dependency. A fixed version is available.
  - Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it.
  - 2 of 33 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 35/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 10 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 72/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 2546 tokens (~49/item across 51 items; 51 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (37% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

sources, B/E/F/G/H/T primitives, modeled diodes, BJT, MOSFET, JFET, MESFET,
voltage switches, OPAMP5, generic two-to-five-terminal X subcircuits, ground,
named nets, wiring, and deterministic layout. Several extended families use
verified generic carrier symbols while retaining native SPICE behavior.
NOT/AND/OR/JK digital parts are schematic-preview maturity.
Generated schematic probes
remain experimental; the high-level experiment tool obtains authoritative
data from the same netlist through Multisim's command engine.
