The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

get_app_rating_history ~152

Return stored public rating history for any App Store app, tracked or not, with deltas: the history the Inspect dialog shows. Asonix records rating history only while some workspace tracks the app, so an app no workspace has tracked has none; for current ratings of any app, use get_app_overview.

get_app_search_ads_keywords ~125

Keywords where an iPhone app's App Store search ads were seen in the last 30 days, in all countries or one. Asonix checks each keyword about once a day, so a missing keyword may still be bid on. observedSharePercent7d is the share of the last 7 days' checks that showed the ad, not impression share. organicRank is null when the app is not in the latest results. status unavailable means ad data is off, not no ads.

Who ranks for a keyword in one storefront; appStoreId gives that app's rank. Uses results Asonix checked in the last 18 hours, else a private live check; saves nothing.

Install

How do I install the Asonix MCP server?

Asonix is a hosted endpoint at https://api.asonix.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the Asonix MCP server?

Asonix is an MCP server listed in the public MCP registry as io.asonix/asonix. ASO for your AI: keywords, rankings, competitors and ads across 2.5M+ App Store apps. This page covers its hosted endpoint (https://api.asonix.io/mcp).

Is the Asonix MCP server safe to use?

Asonix scores 70 out of 100 on VerifyMCP. 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 Asonix MCP server expose?

Asonix exposes 33 tools: get_ai_visibility_overview, get_ai_visibility_reasons, get_ai_visibility_evidence, add_app, create_unreleased_app, and 28 more. Their descriptions and schemas cost roughly 3,792 tokens of context every time the server is loaded.

Does the Asonix MCP server require authentication?

Yes. Asonix asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the Asonix MCP server still maintained?

Asonix is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
