Nothing serious here today

Today is the operative word: we check Chrome Extension Downloader every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 16

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

extension

extension_api_usage

Read the current API key's daily REST/MCP usage and remaining key/account allowance. Requires a key, but remains available after its daily data quota is exhausted. Does not debit data quota; account minute limits still apply.

extension_compare

Compare up to four extensions side by side: users, stars, rating counts, versions, permissions and recent permission changes. For historical comparisons, call extension_trends for each ID; this is not code-similarity detection.

extension_get

Get collected store metadata for one extension, including users, ratings and version. Free without a key for basic metadata only; a key returns the full metadata record. Unknown IDs return not found, never trigger a crawl.

extension_rank_history

Track one extension's position in our overall and category user-count rankings. Returns per-scope history, not official store or keyword search positions. Untracked ranks may be missing.

extension_rankings

Read our saved user-count leaderboard for one date, overall or within a category. Returns positions and pagination; not official store or keyword search ranks. Use extension_rank_history to follow one extension over time.

extension_review_history

Read collected review counts grouped by original publication date and stars, plus version-level ratings and undated/unrated counts. Reconstructed from retained reviews, not historical store rating-count snapshots.

extension_review_insights

Read stored review statistics and star distribution for an extension, optionally by review language. These describe collected reviews, not all store ratings. Missing statistics return null; no refresh is triggered.

extension_review_summary

Get an existing published AI summary of collected reviews, with pros and cons. Use extension_reviews for original comments. Returns null when unavailable and English when a translation is missing; never calls a model or generates a new summary.

extension_reviews

Read original stored reviews for one extension, with text, star and language filters combined using AND. Returns reviews and pagination. For cross-extension or OR queries, use extension_reviews_search.

extension_reviews_search

Search original stored reviews across extensions with AND/OR field filters. Returns reviews and pagination. Example filter: {"field":"body","operator":"contains","value":"subscription"}. Use extensionEid to narrow to an extension.

extension_safety

Inspect permission capabilities, observed permission changes and heuristic store risk signals. Reports evidence and incomplete assessments; not a malware scan, malware probability or safety guarantee.

extension_search

Find extensions by name, description or category name. Returns metadata and pagination, ordered by user count. Use returned IDs for detail and analysis tools; not Chrome Web Store keyword search positions.

extension_source_search

Find extensions by Manifest metadata, permission names, host patterns, descriptions or archived source file paths. Returns metadata matches and snippets, not full-text JavaScript search, source downloads or code-similarity analysis.

extension_top

Browse extensions ranked by current users, average stars or store rating count. Free without a key for the first 10 by users only; omit arguments for that preview. Other sorts and pagination require a key.

extension_trending

Find growing extensions using saved 7/14/30/90-day user or rating-count growth rankings. Candidates have 1K-1M users and at least 500 net new users in the window. Free without a key for the first 10 by 30-day user gain; omit arguments for that preview. Missing comparison data is not zero growth; requests never rebuild rankings.

extension_trends

Read one extension's user-count, store rating-count and average-star history with current metrics and deltas. Use for time-series analysis, not keyword ranks. Missing days are not zero values.

Chrome Extension Downloader — questions

Answers built from our own checks of this server.

What can Chrome Extension Downloader do?

It exposes 16 tools, read directly from the server on our last check. Among them: extension_api_usage, extension_compare, extension_get, extension_rank_history, extension_rankings, extension_review_history and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Chrome Extension Downloader working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 568 ms. The bar chart above shows every period we have measured.

How do I connect Chrome Extension Downloader?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Chrome Extension Downloader need an API key?

No. Chrome Extension Downloader completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Chrome Extension Downloader?

It answers our handshake in 568 ms on average, which is faster than 20% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
