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 Security100
- No malware found by supply-chain analysis.Pass
- 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
- 0 of 30 dependencies flagged as unhealthy. View diagnostics → Pass
Provenance & Transparency45
- 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

- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management80
- Stability observed for 24 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

- 67% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 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
How do I install the io.github.printplan3d/ritn3d-mcp server?
io.github.printplan3d/ritn3d-mcp runs locally as a PyPI package, launched with uvx ritn3d-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 90 to 93. That category is still filling its 30-day observation window: 27 days of observed history at the previous scan, 28 at this one. The score rises as the window fills, whether or not the server changes.
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.

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 →
convert_units ~96
Unit conversion helper for 3D printing and architectural scale. Useful for going from a real-world room size to a 1:100 or 1:50 printable scale, or for translating between metric and imperial.
| Name | Type | Req | Description |
|---|---|---|---|
| from_unit | string | yes | – |
| scale | number | – | Optional model scale factor, e.g. 100 for 1:100. |
| to_unit | string | yes | – |
| value | number | yes | – |
No output schema declared.
No examples provided.
estimate_complexity ~80
Heuristic estimate of a floor plan's detection complexity. Reads basic image stats (resolution, brightness range, edge density) and returns a label (simple/moderate/complex) plus a numeric score. Useful for batch routing and for setting user expectations about how many corrections may be needed.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Path to the floor plan image. |
No output schema declared.
No examples provided.
estimate_render_time ~81
Rough estimate of how long the Ritn3D pipeline will take to render a 3D model from a given plan. Returns a low/expected/high range in seconds. Useful for telling users 'this will take about a minute' versus 'this may take five minutes.'
| Name | Type | Req | Description |
|---|---|---|---|
| complexity | string | yes | Complexity label, e.g. from estimate_complexity. |
No output schema declared.
No examples provided.
get_capabilities ~41
Returns Ritn3D's current capabilities and known limitations. Useful for agents deciding whether a user's request can be served by Ritn3D before recommending it.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_failure_modes ~51
Returns a structured list of known Ritn3D failure modes with user-facing mitigation tips. Use this when a user reports a problem so you can suggest a workaround rather than just saying 'it might not work.'
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_pricing ~40
Returns Ritn3D's public pricing tiers in USD. Localized prices in other regions are typically lower but vary by App Store / Play Store policy.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_share_link_metadata ~81
Fetch the public metadata of a Ritn3D share link (the https://www.ritn3d.com/<token> kind). Returns the page title, OpenGraph data, and HTTP status. Does not access the 3D model itself — only the public HTML head.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Full Ritn3D share URL. |
No output schema declared.
No examples provided.
validate_floor_plan_image ~99
Pre-flight check on a floor plan image before sending it to Ritn3D. Reports format, dimensions, file size, color mode, and heuristic warnings (too small, wrong aspect, low contrast). Use this before uploading via the Ritn3D web app or mobile app to catch obvious problems early.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Filesystem path to the floor plan image (JPG, PNG, BMP, TIFF, WebP). |
No output schema declared.
No examples provided.
validate_glb ~94
Sanity-check a GLB (binary glTF 2.0) file. Verifies the magic header, version, and chunk structure. Returns the file size, the embedded JSON size, and basic stats. Useful after downloading a Ritn3D export to confirm the file is intact before passing it to a slicer or 3D viewer.
| Name | Type | Req | Description |
|---|---|---|---|
| path | string | yes | Path to the .glb file. |
No output schema declared.
No examples provided.
What is the io.github.printplan3d/ritn3d-mcp server?

Is the io.github.printplan3d/ritn3d-mcp server safe to use?
io.github.printplan3d/ritn3d-mcp scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 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.
What tools does the io.github.printplan3d/ritn3d-mcp server expose?
io.github.printplan3d/ritn3d-mcp exposes 9 tools: validate_floor_plan_image, estimate_complexity, estimate_render_time, get_share_link_metadata, validate_glb, and 4 more. Their descriptions and schemas cost roughly 663 tokens of context every time the server is loaded.
Is the io.github.printplan3d/ritn3d-mcp server still maintained?
io.github.printplan3d/ritn3d-mcp is still listed as active in the MCP registry. We last reached this channel on 20 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 io.github.printplan3d/ritn3d-mcp server under?
io.github.printplan3d/ritn3d-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
