## 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 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - 0 of 1 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Licence could not be checked: the licence is shipped as a file inside the package, not declared as a standard (SPDX) licence identifier, so we cannot tell whether it is OSI-approved.
  - Actively maintained (last published 0 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: the captured schema was too large for us to store in full, or the server stopped listing its tools part-way, so we will not judge it on a partial copy.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: the captured tool definitions were too large for us to store in full, or the server stopped listing its tools part-way, so we will not judge them on a partial copy.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: the captured tool definitions were too large for us to store in full (the trim removes the very descriptions this category reads), or the server stopped listing its tools part-way.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 3 categories.** Categories scored 0 because our sandbox has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you.

## Common questions

### What is the FERS — structural FEM MCP server?

FERS — structural FEM is an MCP server listed in the public MCP registry as com.ferscloud/fers. Structural FEM for AI agents: frames, plates, buckling, seismic and Eurocode checks, solved locally. This page covers its npm package (@ferscloud/fers-mcp).

### Is the FERS — structural FEM MCP server safe to use?

FERS — structural FEM scores 47 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### Is the FERS — structural FEM MCP server still maintained?

FERS — structural FEM is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
