## 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 2026-11-05.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 0 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 717 tokens (~102/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability observed for 0 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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: 2 categories.** Categories scored 0 because we could not verify them: 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.

### 2026-11-05 (score 42)

First indexed and scored.

## MCP tools (7)

### `scan_url` (~76 tokens)

Scan a public web page and report its link-preview (Open Graph / Twitter Card) metadata, previews per platform, and issues with fix suggestions. Use it to answer 'why does my link preview look wrong?'.

Input parameters:

- `url` (string, required): The public web page URL to scan for link-preview (Open Graph / Twitter Card) metadata.

### `generate_og_image` (~155 tokens)

Render a 1200x630 Open Graph image from a template id (see list_templates) and text params such as title and subtitle. Returns the permanent image URL to put in og:image, and whether it was already cached. Optional exp (Unix seconds, paid plans) makes the signed URL expire; leave it out for an og:image URL.

Input parameters:

- `exp` (integer): Expiry for the signed image URL, in Unix seconds (paid plans); leave it out for a permanent og:image URL.
- `params` (object): Text values for the template's placeholders, such as title and subtitle, keyed by placeholder name.
- `templateId` (string, required): The id of the template to render (see list_templates).

### `create_template_from_url` (~100 tokens)

Use AI to design a new OG image template from a website's brand (logo, colors, fonts) taken from a URL. Returns the chosen layoutId (a built-in template id usable with generate_og_image), the variables to pass, and the extracted brand kit. Counts against the plan's AI quota.

Input parameters:

- `url` (string, required): The URL of the website whose brand (logo, colors, fonts) the new template is designed from.

### `list_templates` (~45 tokens)

List the OG image templates the workspace can render (built-in and custom) with id, name, version and dimensions. Call this before generate_og_image to pick a templateId.

### `create_short_link` (~148 tokens)

Create a short link with its own link preview. Optional custom slug, and optional A/B variants (each with a title, description, imageUrl or templateId) to test which preview gets more clicks. Returns id, shortUrl and variants. Use the id with get_link_stats.

Input parameters:

- `destination` (string, required): The destination URL the short link redirects to.
- `slug` (string): A custom slug for the short link: lowercase letters, digits, hyphens and underscores, starting with a letter or digit.
- `variants` (array): Up to 3 A/B preview variants, each with its own title, description, image or template, to test which preview gets more clicks.

### `get_link_stats` (~117 tokens)

Get click analytics for a short link by id (from create_short_link): totals plus breakdowns by day, country, device, browser and referrer. Optional from/to dates (YYYY-MM-DD).

Input parameters:

- `from` (string): The first day of the stats window, as a YYYY-MM-DD date.
- `linkId` (string, required): The id of the short link (from create_short_link) whose click stats should be returned.
- `to` (string): The last day of the stats window, as a YYYY-MM-DD date.

### `refresh_preview` (~76 tokens)

Force social platforms to re-fetch a page's link preview after you changed its OG tags or image: bumps the og:image cache-buster, re-scrapes Facebook, and returns the LinkedIn Post Inspector link and the X cache note.

Input parameters:

- `url` (string, required): The URL of the page whose link preview social platforms should re-fetch.
