## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-18.

- **Supply Chain Security**: 97/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - 90 of 208 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to aivigator-ai/open-libka-design-platform).
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 4 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 49/100
  - 25% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 499 tokens (~71/item across 7 items; 4 tools + 3 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**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.

First indexed and scored.

## MCP tools (4)

### `libka_list_blocks` (~65 tokens)

List LibKa blocks

Every LibKa block with the content it fits ("use when"), grouped; plus content that has no block, and what to write for it instead.

Input parameters:

- `group` (string): Only this group: text, how-to, explain, highlight, media, data, ui

### `libka_get_block` (~66 tokens)

Get one LibKa block

Full definition of a block: example syntax, attributes, what the web page, PDF, slides and Word file do with it, accessibility rules, anti-patterns and its JSON schema.

Input parameters:

- `name` (string, required): Block name, such as steps, tabs, chart or ui

### `libka_check` (~65 tokens)

Check LibKa Markdown

Parse LibKa Markdown without building: problems with line numbers (fix all of them), the outline, block counts and how many slides the deck will have. Fast; call it after every change.

Input parameters:

- `markdown` (string, required): The complete LibKa Markdown document, including front matter

### `libka_build` (~208 tokens)

Build a LibKa document

Write the Markdown to a folder and build it: the outputs the document asks for in its front matter (outputs: web, pdf, deck, docx; default web and pdf), or the outputs given here. Guard checks every output (the pages in Chrome, the PDF with veraPDF, the Word file's structure); passing outputs are signed. Returns the files and every Guard finding to fix. Writes files on this machine.

Input parameters:

- `markdown` (string): The document; or give path instead, not both
- `name` (string): File name without extension when markdown is given (default: document)
- `outDir` (string): Output folder (default: LIBKA_OUT, or ./libka-out)
- `outputs` (array): Build these instead of the document's own outputs, e.g. ["web", "deck"] to check slide fit quickly
- `path` (string): An existing .md file to build, only read (images are found next to it)

### Is the LibKa MCP server safe to use?

LibKa scores 76 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 18 October 2026. It declares no install or post-install scripts. 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 LibKa MCP server expose?

LibKa exposes 4 tools: libka_list_blocks, libka_get_block, libka_check, libka_build. Their descriptions and schemas cost roughly 404 tokens of context every time the server is loaded.

### Is the LibKa MCP server still maintained?

LibKa is still listed as active in the MCP registry. We last reached this channel on 18 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 LibKa MCP server under?

LibKa declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
