sonar

Append a screen to a screenshot set (at the end; reorder with sonar_update_screenshot_set). Requires a write-scope API key.

WRITE tool — generates a fresh AI competitive insight for one of your own apps: clusters the keyword gaps vs your competitors into named opportunity themes (with a why-now narrative and per-keyword metrics), writes threat narratives for competitors climbing on your keywords, and diffs against the previous analysis. At most one analysis per app per 7 days (429 with the next available time while in cooldown — use sonar_competitor_landscape to read the current one). Requires an Indie plan (trial counts) and an API key with the write scope.

Calculate an ASO (App Store Optimization) audit score (0-100) for an app. Returns the overall score plus an itemized breakdown of checks (title length, keyword usage, screenshots, ratings, etc.) so you can identify what to improve. Works without an API key (free tier, limited daily use per IP).

Change history for a tracked app — detected releases, metadata edits, screenshot swaps, price changes, and category moves, newest first. Useful for correlating rank movements with what the app (or a competitor) changed. Requires an Indie plan (trial counts).

Extract the most likely target keywords from an app's title and description, ranked by relevance. Useful for understanding what an app (yours or a competitor) is optimizing for. Works without an API key (free tier, limited daily use per IP).

List the keywords tracked for an app in the caller's Sonar workspace, with latest difficulty, popularity, results count, note, and starred_at (favorite/target marker) per keyword. Returns the tracked-keyword ids used by sonar_update_keyword_note and sonar_star_keyword, and the keyword_ids used by sonar_keyword_rankings. Cursor-paginated (default 50 per page). Requires an Indie plan (trial counts).

Look up a single app by its store ID. Returns app metadata including name, developer, category, rating, reviews, installs (Android), and price. Works without an API key (free tier, limited daily use per IP).

Rank history for an app's tracked keywords — daily ranks over the requested window, one history array per keyword. Use this to check how rankings moved after a metadata change or to find keywords trending up or down. Cursor-paginated over keywords (default 50 per page). Requires an Indie plan (trial counts).

Estimate monthly revenue for an app, based on install counts, ratings, and category benchmarks. Returns the dollar estimate, a confidence grade (high/medium/low) with the factors behind it, and the methodology used — always communicate the confidence alongside the number.

Fetch user reviews for an app. Supports filtering by star rating range and sorting by recent or helpful. Useful for sentiment analysis, feature-request mining, and competitive research.

Search apps in the App Store or Google Play by keyword. Returns ranked list of apps with metadata (results are returned in store ranking order). Works without an API key (free tier, limited daily use per IP).

Keywords a tracked competitor currently ranks for (last 7 days of SERP data), with difficulty and popularity per keyword. Pass own_app_id for gap analysis: keywords where the competitor ranks but your app doesn't are marked gap=missing. Cursor-paginated (default 50 per page). Requires an Indie plan (trial counts).

The full competitive keyword picture for one of your own apps vs every tracked competitor, in one call: live stats (keyword gaps where competitors rank and you don't, winnable gaps, competitors climbing on your tracked keywords, keywords you lead), the top gap/threat/lead rows with metrics, and the latest AI insight if one was generated (opportunity clusters, threat narratives, strengths, posture). Read this before deciding which keywords to target next. Requires an Indie plan (trial counts).

WRITE tool — creates a product in the caller's Sonar workspace and starts tracking the given app(s). A product is the cross-store unit (one iOS + one Android app, or just one of either). Returns the product id and the Sonar app ids needed by sonar_track_keywords and sonar_track_competitor. Requires an Indie plan (trial counts) and an API key with the write scope.

Create an app-store screenshot set for a product. Read sonar_screenshot_layout_guide first, then author the screens array. The set is immediately visible/editable for humans in the Screenshot Studio (studio_url in the response). Requires a write-scope API key.

WRITE tool — delete an alert subscription in the caller's Sonar workspace. Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — delete a product and untrack its apps in the caller's Sonar workspace. Requires an Indie plan (trial counts) and an API key with the write scope.

Delete one screen from a screenshot set. A set keeps at least one screen — deleting the last one is rejected. Requires a write-scope API key.

Permanently delete a screenshot set and everything in it (screens, translations). Irreversible — confirm with the user before deleting work they may want. Requires a write-scope API key.

WRITE tool — stop tracking one keyword/app pair in the caller's Sonar workspace. Identify the pair by its tracked-keyword id (from sonar_app_keywords). Requires an Indie plan (trial counts) and an API key with the write scope.

Render a screenshot set to store-ready PNGs SERVER-SIDE (no browser needed) and save them as one ZIP per locale in output_dir — ready for App Store Connect / Play Console upload. Rendering happens through the same engine as the Screenshot Studio editor. Writes to the filesystem of the machine running the MCP server, so this tool is for local (stdio) use; over the hosted transport call GET /api/v1/screenshots/sets/:id/export directly instead.

Get full details for one tracked app in the caller's Sonar workspace: store metadata plus up to 90 daily snapshots of rating, review count, version, and installs. Requires an Indie plan (trial counts).

Fetch a screenshot set in full: every screen's layout JSON plus per-screen translation overrides keyed by locale. By default inline image data is replaced with placeholders to keep the response readable.

Difficulty + popularity for a specific keyword (or up to 25 in bulk). Use this when you already know which keywords you care about — costs 1 credit per keyword. Works without an API key for up to 5 keywords/day (free tier, per IP); an API key removes that cap. Use sonar_keyword_search instead when you want related keyword ideas alongside metrics.

SERP history for one tracked keyword — which apps ranked in the top results on each measured day, newest first. Use this to see who competes on a keyword and how the top spots shifted over time. The keyword must be tracked in the caller's Sonar workspace. Requires an Indie plan (trial counts).

Research a keyword and related terms. Returns difficulty (0-100), popularity score, and results count for the seed keyword plus related autocomplete suggestions. Use this to find keywords worth targeting.

Get autocomplete suggestions for a seed keyword from the App Store or Google Play. Returns terms with a priority score (higher = more searched). Lighter and faster than sonar_keyword_search — use when you only need term ideas without difficulty/popularity scoring. Works without an API key (free tier, limited daily use per IP).

List your alert subscriptions — each rule defines a change type (rank drops, review spikes, etc.), its scope (a specific app or org-wide), threshold, and whether it's enabled. Requires an Indie plan (trial counts).

List the apps tracked in the caller's Sonar workspace (own apps + competitors), each with its latest snapshot (rating, review count, version, installs). Returns the Sonar app UUIDs needed by sonar_get_app, sonar_app_keywords, sonar_app_rankings, and sonar_app_changes. Cursor-paginated (default 100 per page). Requires an Indie plan (trial counts).

List your products with their linked store versions and competitor counts. Use it to discover product/app UUIDs. Requires an Indie plan (trial counts).

List a product's app-store screenshot sets (metadata only: store, device size, locales, studio_url). Use sonar_get_screenshot_set for full layouts.

WRITE tool — remove a competitor from a product in the caller's Sonar workspace. Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — runs an AI keyword discovery scan on a tracked competitor: generates the search terms the competitor's listing is optimized for (brand terms included), queues them for SERP verification, and verifies the first batch inline (~30s), recording both apps' ranks. Returns generated/queued/verified_now counts; the rest verify in the background over the following hours — read results with sonar_competitor_keywords. Requires an Indie plan (trial counts) and an API key with the write scope.

List the device sizes supported for app-store screenshot sets, with their canvas dimensions (the pixel coordinate space all layouts use) and which store each belongs to. Pick a device here before sonar_create_screenshot_set.

The layout-format reference for Sonar screenshot sets. Call this ONCE before creating or editing screenshot layouts — it documents the layout JSON schema, coordinate system, image handling (remote URLs), flowing background shapes, fonts, translation overrides, and the recommended workflow.

WRITE tool — create or update an alert subscription in the caller's Sonar workspace. Upserts on (type + scope): re-submitting the same type/scope updates the existing rule. Omit threshold for the per-type default; omit scope_app_id for an org-wide rule. Requires an Indie plan (trial counts) and an API key with the write scope.

Write a locale's translation overrides for screens in a screenshot set (text copy, localized captures/images). Geometry and styling always come from the source layout; anything not overridden falls back to it. The locale is auto-enabled on the set. Requires a write-scope API key.

WRITE tool — stars or unstars a tracked keyword in the caller's Sonar workspace. A star marks the keyword as a favorite/target the user is actively pursuing; starred keywords carry a starred_at timestamp in sonar_app_keywords results. Idempotent: re-starring refreshes the timestamp, unstarring a non-starred keyword is a no-op. Requires an Indie plan (trial counts) and an API key with the write scope.

Get a store top chart (free / paid / grossing, overall or by category) with day-over-day movement: per-app rank delta, apps new to the chart, biggest movers and apps that dropped out. Use to see what's rising in a market or category. Note: summary, movers and droppedApps always describe the full top 100 — limit truncates the returned entries only. Movement is empty on the first day a chart is requested (no previous snapshot yet). Works without an API key (free tier, limited daily use per IP).

WRITE tool — links the second-store version of an existing Sonar product (e.g. the product already tracks the iOS app and you want to add the Android version, or vice versa). Each product holds at most one iOS + one Android app; to start tracking a brand-new app, use sonar_create_product instead. Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — adds a competitor app under a Sonar product so its keywords and rankings get tracked alongside the product's own app. The product must already have its own app linked in the same store as the competitor. Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — starts daily rank tracking for one or more keywords on an app in the caller's Sonar workspace. Idempotent: re-posting the same terms reports them as already_tracked instead of creating duplicates. Returns per-keyword outcomes (created / already_tracked / failed). Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — untrack an app and its associated tracking data in the caller's Sonar workspace. Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — bulk-untrack keywords for an app in the caller's Sonar workspace. Pass all: true to remove every tracked keyword, OR ids: [...] to remove specific ones (exactly one of the two). Requires an Indie plan (trial counts) and an API key with the write scope.

WRITE tool — sets or clears the note on a tracked keyword in the caller's Sonar workspace (e.g. why it's tracked, an optimization hypothesis, a reminder). Idempotent: re-sending the same note is a no-op. Requires an Indie plan (trial counts) and an API key with the write scope.

Replace one screen's layout in a screenshot set. Whole-document replace — fetch the current layout, modify it, send it back. The change shows up immediately in the Screenshot Studio for human review. Requires a write-scope API key.

Rename a screenshot set, replace its extra-locale list, and/or reorder its screens. Returns the updated set (with image data stripped). Requires a write-scope API key.
