Category Design and Media
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
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
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 (Apache-2.0).Pass
- Actively maintained (last published 2 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability64
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 513 tokens (~171/item across 3 items; 3 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 Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 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
Unverified: 1 category
A category scored 0 because we could not verify it: 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.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
check Check a video ~133
Run Kodecz's automatic checks on every frame without rendering: text over the presenter's face, captions on one line, the safe area of a declared social destination, contrast over the real background, zoom timing. Returns the JSON result, each problem with its frame, and pictures of the worst frames. `ok: false` means a rule was broken: fix and check again.
| Name | Type | Req | Description |
|---|---|---|---|
| folder | string | yes | Video folder (the one with index.html), absolute or relative to the working directory |
| id | string | yes | The id in the page's <script type="application/json" id="kodecz"> block |
No output schema declared.
No examples provided.
preview Preview frames ~122
Draw some frames of a Kodecz video as lossless PNGs (the same pixels as the render, one to two seconds) and return them as images. Use it to look at what you wrote instead of guessing.
| Name | Type | Req | Description |
|---|---|---|---|
| folder | string | yes | Video folder (the one with index.html), absolute or relative to the working directory |
| frames | array | yes | Frame numbers, e.g. [0, 45, 149] |
| id | string | yes | The id in the page's <script type="application/json" id="kodecz"> block |
No output schema declared.
No examples provided.
render Render a Kodecz video ~197
Render a Kodecz video folder to MP4 (GPU with NVENC when there is one, CPU with x264 when not). Returns the render's JSON result line. Run `check` first.
| Name | Type | Req | Description |
|---|---|---|---|
| alpha | boolean | – | Transparent layer as raw HEVC with alpha (GPU only, no audio) |
| cpu | boolean | – | Render on the CPU even when there is a GPU |
| folder | string | yes | Video folder (the one with index.html), absolute or relative to the working directory |
| frames | integer | – | How many frames to render from `from` |
| from | integer | – | First frame to render |
| hevc | boolean | – | HEVC instead of H.264 (GPU only) |
| id | string | yes | The id in the page's <script type="application/json" id="kodecz"> block |
| output | string | yes | Output file (.mp4; .hevc with alpha) |
No output schema declared.
No examples provided.
