Chrome extension data: free previews; API key for full reviews, comparisons and permissions.
Remote MCP server for Chrome extension market data: search extensions, read trends, rankings, reviews and permission signals, with free previews and an API…
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.extensiondownloader%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}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.
qpagepageSizeGet 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.
eidrequiredRead 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.
eidrequireddayslocaleTrack 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.
eidrequireddaysInspect permission capabilities, observed permission changes and heuristic store risk signals. Reports evidence and incomplete assessments; not a malware scan, malware probability or safety guarantee.
eidrequiredlocaleCompare 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.
eidsrequiredBrowse 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.
pagesortpageSizeFind 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.
pagesortpageSizefastGrowthwindowDaysRead 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.
pagelimitrankDatescopeKeyscopeTypeGet 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.
eidrequiredlocaleRead 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.
eidrequiredlanguagewindowDaysRead 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.
eidrequiredRead 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.
qeidrequiredpagesortratinglanguagepageSizeSearch 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.
pagesortlogicfilterspageSizeFind 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.
qrequiredfieldlimitRead 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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
