Tools
| Tool | Description | Behaviour |
|---|---|---|
| changes_list | Use this when the user asks what changed in a store: chart moves, featuring, launches, delistings, metric moves or MCP changes, newest first with counts per type. Do not use for a chart's full current order; use charts_get. | Read-only |
| charts_get | Use this when you need a chart now or at a past time, with movement and 1-based positions. Do not use for a listing across charts; use listings_profile. | Read-only |
| featuring_history | Use this when you need when and where apps were featured, per app or home shelf, over at most 30 days. Do not use for current shelf order; use charts_get. | Read-only |
| feedback_send | Use this when OpenApps' tools or data fail the user: an error, data the user says is wrong (such as an app bound to the wrong listing), a missing capability, or something confusing. Ask the user before sending a report they did not ask for. It is stored privately with the caller's account and client; no reply comes in this conversation. Summarize; never include secrets or personal data. Do not use for other servers or the client app; it does not finish the user's task. | Changes data |
| fetch | Use this when ChatGPT deep research needs a document for an id returned by search: listing, app, tag, chart or MCP toolset. Do not use for ids outside search results. | Read-only |
| leaderboards_get | Use this when the user asks which apps lead a store by a published number. claude: installs, popularity_score, trending_score, gh_stars; cursor: dir_installs, dir_stars. Do not use for chart positions; use charts_get. | Read-only |
| listings_profile | Use this when you need a listing profile, or up to 5 (Pro): its app, country availability, ranks, metrics and MCP tools. Stale or refused countries read unknown. Do not use for discovery; use listings_search. | Read-only |
| listings_search | Use this when you need an app's ref from its name, its publisher, a brand it works with or what it does ("create jira ticket"); one row per app, best match first. Do not use for popularity or rankings; use charts_get. | Read-only |
| market_get | Use this when you need store sizes, weekly launches, app kinds or MCP ecosystem statistics. Do not use for app profiles or rankings. | Read-only |
| mcp_toolset_get | Use this when you need a tracked app or server's stored MCP tools or changes. at selects a past snapshot; diff_from compares versions. Do not use for arbitrary URLs; only tracked servers. | Read-only |
| new_list | Use this when the user asks which apps are new in a store since a time, by launch date or else the day each went live. Do not use for rank or toolset changes; use changes_list. | Read-only |
| scores_list | Use this when the user asks which apps are popular in a store over the last month: OpenApps Rank, a 28-day aggregate of its popularity charts, with tier and momentum. Do not use for one day's chart order (charts_get) or published counts (leaderboards_get). | Read-only |
| search | Use this when ChatGPT deep research needs listings, apps, tags (query tag:<id>), charts or tracked MCP URLs. Returns typed ids for fetch. Do not use for rankings or events; use charts_get or changes_list. | Read-only |
| stores_get | Use this when you need stores, app counts, countries, freshness, charts or metrics. Pass store for chart names. guide returns a playbook's steps: weekly_brief (a store's week), competitor_watch (compare apps), audit_my_server (an MCP server's tools). Do not use for rankings; use charts_get. | Read-only |
