Trust breakdown (7 categories)

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 Security0
  • No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
  • Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
  • Install-script risk not yet assessed.Unverified
  • Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
Provenance & Transparency48
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
  • Clear OSI-approved license (LGPL-2.1-or-later).Pass
  • Actively maintained (last published 32 days ago).Pass
  • Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability0
  • Schema quality not yet verified: we do not have a sandbox capture of the MCP schema this version of the package serves yet.Unverified
Stability & Change Management0
  • Stability not yet verified: we do not have a sandbox capture of the MCP schema this version of the package serves yet.Unverified
Tool Coverage0
  • Tool coverage not yet verified: we do not have a sandbox capture of the tool definitions this version of the package serves yet.Unverified
Tool Safety0
  • Tool safety not yet verified: we do not have a sandbox capture of the tool definitions this version of the package serves yet.Unverified
Capabilities0
  • Protocol version not yet verified: we do not have a sandbox capture of the MCP handshake this version of the package performs yet.Unverified

Unverified: 6 categories

Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Install

How do I install the FreeCAD MCP server?

FreeCAD MCP runs locally as a container image, launched with docker run --rm -i ghcr.io/blwfish/freecad-mcp:latest. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

Diagnostics

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

Provenance No attestation

The registry publishes no build provenance for this version, so there is nothing to verify.

MCP tools

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 →

Tools for package channels are captured by running the package in an isolated sandbox. The most recent sandbox run could not capture a tool list from this package.

Common questions

What is the FreeCAD MCP server?

FreeCAD MCP is listed in the public MCP registry as io.github.blwfish/freecad-mcp. Control FreeCAD from Claude, 3D modeling, PartDesign, CAM toolpaths, and more via 30+ tools. This page covers its container image (ghcr.io/blwfish/freecad-mcp).

Is the FreeCAD MCP server safe to use?

FreeCAD MCP scores 10 out of 100 on VerifyMCP. 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 FreeCAD MCP server still maintained?

FreeCAD MCP is still listed as active in the MCP registry. We last reached this channel on 6 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the FreeCAD MCP server under?

FreeCAD MCP declares the LGPL-2.1-or-later licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
