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 build step with no custom scripting around it. View diagnostics → Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to loopcut-ai/loopcut). View diagnostics → Pass
- Clear OSI-approved license (GPL-3.0-or-later).Pass

- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability62
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2224 tokens (~202/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage99

- 98% 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 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

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

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 →
asset_search Loopcut cloud asset library ~247
Search free CC0 libraries (Poly Haven, ambientCG, Physically Based) for models, materials, HDRIs and textures, with licence, size, preview and download details. Try it before generating a model or texture. Free: runs at once and returns the results.

|---|---|---|---|
| kind | – | – | Asset category to search: one kind, a list of kinds, or any for every kind. Defaults to model. |
| license | string | – | License filter. Defaults to cc0; any currently returns the same CC0 sources. |
| limit | integer | – | Maximum number of search results. Defaults to 10. |

| min_resolution | integer | – | Minimum longest side in pixels of the largest texture, HDRI or model texture set offered by the source. Assets with no stated resolution are excluded when set. Defaults to no minimum. |
| query | string | yes | Search terms describing the desired asset; at most 1000 characters. |
| sources | array | – | Libraries to search. Defaults to all. |
No output schema declared.
No examples provided.
image_to_3d Image to 3D ~225
Make a textured 3D model (GLB) from a prompt, a local reference image, or both. For new props and concept meshes, not exact CAD. Takes 1-5 minutes. Returns a quote and spends nothing; call job_start once the user agrees to the price.

| wait_seconds | integer | – | Seconds to wait before returning progress (default 40). |
No output schema declared.
No examples provided.
job_status Job status and results ~127
Wait for a job, then download its results (hash-checked; finished files are kept). Call it again until the result has the files or the status is failed or canceled. A first render can spend minutes starting a GPU.

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
loopcut_login Sign in to Loopcut ~82
Sign in to the user's Loopcut account, or switch accounts. Any tool called while signed out does this by itself. Opens the sign-in page in the browser and waits; if it returns a verification_url instead, show it to the user and call again after they approve.
| Name | Type | Req | Description |
|---|---|---|---|
| wait_seconds | integer | – | Seconds to wait before returning progress (default 40). |
No output schema declared.

| topology | string | – | Preferred output face topology. Defaults to quads. |
No output schema declared.
No examples provided.
render_quote Cloud rendering ~475
Price a cloud render of a saved .blend on an RTX 4090. Packs the scene and every texture, library and cache it uses with a local headless Blender and uploads what the cloud lacks. While the result says status "preparing", call again with the same arguments. Frames default to frame 1 only. Check warnings for missing files (they render pink). Returns a quote and spends nothing; call job_start with the quote_id once the user agrees to the price.
| Name | Type | Req | Description |
|---|---|---|---|
| blend | string | yes | Path to the saved .blend file. |
| blender | string | – | Blender executable to pack with (default: LOOPCUT_BLENDER, PATH, then the usual install folders). |

| samples | integer | – | Samples per pixel: Cycles samples, or EEVEE render samples. Defaults to 128 for Cycles and 64 for EEVEE. |
| turntable | object | – | Render a 360° turntable instead of the scene camera: a generated camera orbits the target objects (or the whole scene) once across frame_start..frame_end, so the frames loop seamlessly. If frame_end… |
| wait_seconds | integer | – | Seconds to wait before returning progress (default 40). |
No output schema declared.
No examples provided.
sound_effect Sound effects ~161
Make a sound effect (WAV, 0.5-30 s) from a description: impacts, ambience, foley. Not speech or music. Returns a quote and spends nothing; call job_start once the user agrees to the price.

What is the Loopcut MCP server?
Loopcut is an MCP server listed in the public MCP registry as io.github.loopcut-ai/loopcut. Blender cloud tools for agents: GPU renders, free assets, 3D models, character motion, sound, voice. This page covers its PyPI package (loopcut).
Is the Loopcut MCP server safe to use?
Loopcut scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 24 October 2026. Its build provenance is signed and verified. 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 Loopcut MCP server expose?
Loopcut exposes 11 tools: loopcut_login, loopcut_account, render_quote, asset_search, image_to_3d, and 6 more. Their descriptions and schemas cost roughly 1,997 tokens of context every time the server is loaded.
Is the Loopcut MCP server still maintained?
Loopcut is still listed as active in the MCP registry. We last reached this channel on 24 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 Loopcut MCP server under?
Loopcut declares the GPL-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.
