Available components
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 Security50
- Malware scan not yet available for this package.Unverified
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it. View diagnostics → Pass
- 4 of 50 dependencies flagged as unhealthy. View diagnostics → Partial
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 (AGPL-3.0-or-later).Pass
- Actively maintained (last published 34 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability0
- Schema quality not yet verified: the captured schema was too large for us to store in full, so we will not judge it on a partial copy.Unverified
Stability & Change Management0
- Stability not yet verified: the captured schema was too large for us to store in full, and comparing a partial copy would report our own trimming as a change.Unverified
Tool Coverage0
- Tool coverage not yet verified: the captured tool definitions were too large for us to store in full, so we will not judge them on a partial copy.Unverified
Tool Safety0
- Tool safety not yet verified: the captured tool definitions were too large for us to store in full, and the trim removes the very descriptions this category reads.Unverified
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass
Unverified: 4 categories
Categories scored 0 because our sandbox run of this package 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. How we score packages →
How do I install the Kiln MCP server?
Kiln runs locally as a PyPI package, launched with uvx kiln3d. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →

What is the Kiln MCP server?
Kiln is an MCP server listed in the public MCP registry as io.github.codeofaxel/kiln. Kiln MCP server for agents: design, slice, print, monitor, and recover physical objects safely. This page covers its PyPI package (kiln3d).
Is the Kiln MCP server safe to use?
Kiln scores 29 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 23 September 2026. 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 Kiln MCP server still maintained?
Kiln is still listed as active in the MCP registry. We last reached this channel on 23 September 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 Kiln MCP server under?
Kiln declares the AGPL-3.0-or-later licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
