averra_extract_url

Convert any webpage URL into clean, LLM-ready Markdown using Averra Extract. This tool fetches the page (executing JavaScript via a headless browser), strips navigation/ads/UI clutter via Mozilla Readability, converts the main content to Markdown, and returns it along with metadata (title, word cou…

averra_create_api_key

Create a new Extract API key for the authenticated account. IMPORTANT: The plaintext key is returned ONLY ONCE in this response. It cannot be retrieved later — only the prefix is stored for display. If lost, the key must be revoked and a new one created. The new key automatically inherits the plan…

averra_list_api_keys

List all API keys for the authenticated account. Returns metadata only — the actual plaintext keys are never returned (only prefixes). Includes both active and revoked keys, ordered by creation date (newest first). Args: - response_format ('markdown' | 'json', optional): Output format. Default '…

averra_revoke_api_key

Revoke an Extract API key by its ID. The key is immediately deactivated and cannot be reactivated — create a new key if needed. SAFETY: You cannot revoke the key that is currently authenticating the MCP server itself (the one set in AVERRA_EXTRACT_API_KEY). Attempting to do so returns a 400 error. …

averra_check_usage

Check the current month's Extract API usage and remaining quota for the authenticated account. Usage is counted per user across all API keys (not per key). Cached requests also count against the quota. The counter resets at the start of each calendar month (UTC). Args: - response_format ('markdo…

// full audit trail

The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.

// improvement guidance — verified publishers only

We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
