Claude Code: deny. ### `console_set_version_notice` - The name "console_set_version_notice" says "set": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Put a warning on one stored build of your app — `vulnerable` or `withdrawn`, a message of up to 300 characters, and optionally the version code to use instead — or lift it (`lift: true`). With `blockDownload: true` downloads of that build are refused. Applies immediately and is reversible; it does not delete anything. Take `apkId` from console_security_report. Needs the uploader role or above. ``` ### `console_update_listing` - The name "console_update_listing" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Change the text visitors read on your app's page: the short description (≤80 characters), full description (≤4000, plain text), what's new (≤500) and a YouTube link. Omit a field to keep it; pass null or an empty string to show Google Play's text for it. Goes live immediately; our moderators review afterwards. Needs the admin or owner role. Name and icon cannot be changed. ``` ## Changes things (7) Creates or changes something that can be changed back. Claude Code: ask. ### `check_availability` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Free. Whether we hold a downloadable build of each of up to 100 packages, the newest one's versionName and versionCode, and `versions`: every build we hold by versionCode and versionName, highest code first — the cheap way to check for updates before calling list_versions or get_download_url. Send every package you are checking in one call rather than looping. Each lands in one of three lists: `items` for packages we know (`available` false when we hold no build), `notFound` for ones we have never seen, and `refused` for ones we will not serve at all, with the reason a download would give. ``` ### `console_app_stats` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Downloads of one of your apps: per UTC day for the last 30 days (with the 30 before for comparison), the lifetime total, and the top countries of the last 7 days. Counts come from our own download log, not Google Play. Free. ``` ### `console_security_report` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Every build we store for one of your apps with our scan verdict, VirusTotal counts, signature scheme, how its signing key compares with the keys on record, and any notice you have put on it — plus a one-line verdict on the signing history. `verdict: null` means not scanned, which is not the same as clean. The `apkId` here is what console_set_version_notice takes. Free. ``` ### `console_upload_status` - The name "console_upload_status" says "upload": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Where one upload stands, with the scan summary once it has one (VirusTotal counts, signing certificates and how each compares with the keys on record). Poll every 15–30 seconds while status is verifying, scanning or publishing; `held` waits for a person and can take days. Free. ``` ### `get_download_url` - The name "get_download_url" says "get": a word for reading. - The server marks it as not read-only (readOnlyHint: false). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "get_download_url" says "get" and "url": it reads web pages, which anyone can write. The description's first sentence says "url": it reads web pages, which anyone can write. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text Mint a short-lived signed URL for one build — the newest held unless you pass an apkId from list_versions. Costs 10 credits — the most expensive call here, and the only one that hands over a file. Check get_version_security before handing anything to a person. The URL expires in about 5 minutes; fetch it promptly and do not store it. The response carries the file's `sha256` — verify what you downloaded against it, because the signature is on the URL and not on the bytes. ``` ### `request_fetch` - The name "request_fetch" says "request": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Ask us to download an app from Google Play when list_versions came back empty. Costs 10 credits, even when we already have builds (`READY`) or Google Play doesn't list the app — so call list_versions first. Free only when a fetch for the app is already running (`FETCHING`). A fetch usually takes a few minutes. Poll get_fetch_status every 10–30 seconds — not this tool — and call list_versions once it says READY. Paid apps and apps Google Play will not deliver to us are refused with the reason. An app not in the catalogue yet is looked up on Google Play live, for up to 20 seconds; UPSTREAM_UNAVAILABLE / UPSTREAM_BUSY then is refunded and means Play did not answer in time, not that the app does not exist — retry after a few seconds. ``` ### `request_variant` - The name "request_variant" says "request": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Ask for an on-demand build of an app's newest release that the ordinary download does not carry: every language (`+all-langs`), the 32-bit ARM build (`armeabi-v7a`), both ARM ABIs in one bundle (`universal`), the newest build for an older Android version (`@sdkNN`), or exactly what one real device gets (`device:`). We must already hold the ordinary build — call list_versions first, and request_fetch if it is empty. Costs 10 credits, even when the variant is already built (`READY`); free only when a build of that variant is already running (`FETCHING`). A build usually takes a few minutes: poll get_variant_status, not this tool, then pass its `variantId` to get_download_url. Builds are temporary — see `expiresAt`. ``` ## Only reads (27) Looks things up and changes nothing. Claude Code: allow. ### `compare_versions` - The name "compare_versions" says "compare": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text What changed between two releases: permissions gained and lost, whether the signing key moved, size and minimum Android. Name either side by version name or by version code — the code is tried first, because a version name is free text the developer sets and is often a placeholder. Order does not matter; the higher build number is treated as the newer. Check `permissionsKnown` before reading two empty permission lists as 'nothing changed'. ``` ### `console_list_apps` - The name "console_list_apps" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The apps you manage in the APKCube Developers Console — every app of every developer whose team you are on, 50 a page, with your role on each. Only works for a signed-in user (OAuth) on a verified developer's team. Free. ``` ### `console_list_uploads` - The name "console_list_uploads" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text Builds submitted for your apps from the console or the Publishing API, newest first, with each one's status (uploading, verifying, scanning, held, published, rejected …) and, for a held or rejected build, the reason and its stable code. Pass packageName for one app. Free. ``` ### `get_account` - The name "get_account" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text How many credits are left on the key you are using, and what that key is. Free. Every successful call also reports this in `_meta`, so reach for this one when you need to know before you spend — a download costs 10 — or when your calls have been failing and you have not seen a balance in a while. ``` ### `get_app` - The name "get_app" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Full record for one package: description, screenshots, rating, tags, and whether a download would be refused. Does NOT list downloadable files — use list_versions for those. An app not in the catalogue yet is looked up on Google Play live, for up to 20 seconds; UPSTREAM_UNAVAILABLE / UPSTREAM_BUSY then is refunded and means Play did not answer in time, not that the app does not exist — retry after a few seconds. ``` ### `get_apps` - The name "get_apps" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Summary rows for up to 100 package ids in one call — use this instead of calling get_app in a loop. Costs 1 credit PER PACKAGE, so a hundred ids cost a hundred credits however they arrive. Ids we do not hold come back in `notFound` rather than failing the call. Returns the SUMMARY row, not the full record: it is cheaper than get_app (5) because it answers less, so reach for get_app only when you need the description or the screenshots for a particular one. ``` ### `get_fetch_status` - The name "get_fetch_status" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Where the fetch request_fetch started stands now: FETCHING (keep waiting), READY (call list_versions), or FAILED with a reason. Free when the fetch is still running (`FETCHING`); the final answer costs 1 credit, and so does a check when no fetch was requested (`FETCH_NOT_FOUND`). When FAILED carries `terminal: true`, Google Play will not deliver this app to us and asking again will not help; otherwise request_fetch may be retried. ``` ### `get_manifest` - The name "get_manifest" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text What the artifact's own AndroidManifest.xml says beyond the permissions it requests — targetSdk, compileSdk, debuggable, cleartext traffic, backup, sharedUserId, install location, uses-feature, uses-library, and the components it exports without a permission guard — plus the native libraries it ships, and our rules read off the pair as `findings`. Defaults to the newest build. A KEY ABSENT INSIDE `manifest` means the manifest is silent about that attribute, never that it declares the platform default; `manifest: null` means nobody read it at all, and an empty `findings` beside that is not an all-clear. `versionMismatch` is the one to escalate: non-null means the file's own version disagrees with what the listing claims, which is what a swapped or relabelled artifact looks like. Use get_raw_scan if you want the stored record without our rules applied. ``` ### `get_play_details` - The name "get_play_details" says "get": a word for reading. - Tag private-data: The description's first sentence says "contact": it reads contacts. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Google Play's full store listing for one package, in any storefront: the star histogram, install estimate, IAP price range, release date, declared permissions, content-rating descriptors, legal publisher and contact details — the store data get_app leaves out. Usually null: the written-review count, sale pricing and the Play Pass and pre-registration flags. Pass `lang`/`country` for another storefront (prices, text and availability differ); the default en/us listing is served from our own scrape while it is fresh and scraped and stored otherwise. Works for packages outside the catalogue. Charged even when Google Play doesn't list the app (`APP_NOT_FOUND`); a busy or failed Google Play is refunded. ``` ### `get_protection` - The name "get_protection" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Whether this build is wrapped in a commercial protector — DexProtector, Jiagu, Bangcle, Legu, AppSealing, Google's own PairIP — and what that means for everything else you can find out about it. Defaults to the newest build. A PROTECTOR IS NOT A MALWARE SIGNAL: anti-piracy, anti-tamper and anti-cheat are what these are sold for, and saying an app is 'suspicious' because it is packed is wrong about a large part of the catalogue. What it does mean is that the app's real code is not in classes.dex for anyone to read, so an empty SDK list, a short permission list or any other analysis of the same artifact is a floor and not a census — call this BEFORE you report that a build carries no trackers. `analyzed: false` means the archive was never opened, which is not the same as an unpacked build. Relay `summary` whole: it carries the finding and the bound in one sentence. ``` ### `get_raw_scan` - The name "get_raw_scan" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text The whole stored analysis record for one build, exactly as stored and with none of our rules applied — for when you want to judge the facts yourself rather than read our conclusions. It carries two things no other tool publishes: the EVIDENCE DIGEST every SDK match is drawn from (dex package prefixes, manifest component names, intent actions, how much code was read), so you can match it against your own corpus; and each signing certificate's serial and signature algorithm. Also the raw VirusTotal counters and every flagging vendor. Prefer the narrower tools when you want an answer — get_version_security, get_protection, list_trackers, list_permissions, get_manifest — and reach for this when you want the inputs. A build nobody has scanned is `scanned: false`, which is not a clean result. ``` ### `get_signing_history` - The name "get_signing_history" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Which certificate signed which releases of a package, and where the key moved. Android will only install an update signed by the key that signed what is already on the device, so a `hasKeyReplacement: true` means the newer build is not an update of the older one — it is a different app under the same package name, which is what a repackaged app looks like. `unreadVersions` lists releases whose signature we never read; those are gaps, not agreement. ``` ### `get_variant_status` - The name "get_variant_status" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "url": it reads web pages, which anyone can write. Description, as the server wrote it: ```untrusted-server-text Where one variant of an app stands: READY with the build (its `variantId` goes to get_download_url), FETCHING (keep waiting, 10–30 seconds between checks), FAILED with a reason (request_variant retries), or NEEDS_FETCH (nobody has asked for it, or it expired — call request_variant). Free when the build is still running (`FETCHING`); any other answer costs 1 credit, including when nobody has requested that variant (`NEEDS_FETCH`). ``` ### `get_version_security` - The name "get_version_security" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text What one build actually IS: its SHA-256, the anti-malware verdict, the certificates that signed it, and every Android permission it declares with a plain-English gloss. Defaults to the newest build, so you do not need list_versions first. `findings` is the part to read first: it applies our rules to the manifest and native facts on the same response and names what they imply — a debuggable build, a version that disagrees with the listing, cleartext traffic, components any app on the device can start, a packer. Two severities, `warning` and `notice`, and NEITHER is a verdict; an empty `findings` is not an all-clear, because a manifest nobody read produces no findings either. Read this BEFORE recommending an install, and read the nulls carefully — `scanned: false` and `virusTotal: null` mean nobody has looked, which is not the same as clean, and `permissions: null` means the manifest was never read, which is not the same as an app that asks for nothing. ``` ### `list_categories` - The name "list_categories" says "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text The category taxonomy, for filtering a search. Free — this call costs no credits. ``` ### `list_chart` - The name "list_chart" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text A ranked section of the catalogue. Google Play's charts (hot, grossing, latest, editors-choice), the catalogue's newest releases (new), what people downloaded here in about the last day (popular), or the newest builds we stored (updated). An unrecognised section falls back to 'hot' rather than failing. ``` ### `list_developer_apps` - The name "list_developer_apps" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Every app we hold from one publisher, most-installed first. The slug comes from `developerSlug` on any app row. ``` ### `list_developer_certificates` - The name "list_developer_certificates" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Every signing key on record for one publisher's apps — lookup_certificate read the other way round. Each key says how many of the publisher's apps it signs and, in `elsewhere`, how many packages OUTSIDE the publisher it is also on: zero is ordinary, above zero is a key shared across the publisher's accounts or somebody else's builds signed with it, and lookup_certificate on that fingerprint lists which. All keys in one answer, no pages. BOUNDED, and `note` says how: it covers the publisher's apps we have ingested and scanned. Free when we hold no signing record for any of the publisher's apps (`total: 0`). The slug comes from `developerSlug` on any app row. ``` ### `list_permissions` - The name "list_permissions" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Every Android permission this build declares, sensitive ones first, each with a readable label, its capability family and a sentence saying what the app can actually do with it. Defaults to the newest build. This is the same labelling compare_versions diffs, so the two cannot name the same permission differently. THE NULL IS THE PART TO READ: `permissions: null` means the manifest was never read and is NOT a claim that the app asks for nothing — an empty array is that claim. `sensitive` is the count worth quoting; a long list of ordinary permissions is what almost every app looks like. `defines` is separate and often misread: those are permissions this app declares for OTHER apps to hold, not things it is asking for. ``` ### `list_reviews` - The name "list_reviews" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "list_reviews" says "list" and "review": it reads comments, which other people can write. The description's first sentence says "review": it reads comments, which other people can write. Description, as the server wrote it: ```untrusted-server-text One page of Google Play user reviews for a package, live: stars, text, helpful votes, the app version the reviewer ran, and the developer's reply. Sort by newest (default), rating or helpfulness; up to 100 a page. Walk further pages by passing `nextCursor` back as `cursor` with the same sort, num and storefront — each page is a separate charge, so ask for what you need. Free when the page is empty (an empty `items`); a busy or failed Google Play is refunded. ``` ### `list_sdks` - The name "list_sdks" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text What OTHER companies' code is inside an app: the ad, analytics, attribution, crash-reporting, push and sign-in libraries matched in the build, each with its vendor and where it was recognised. Defaults to the newest build. This is the privacy question, not the safety one — these libraries are ordinary parts of shipping an app, so report them as what the app carries and never as evidence of harm. READ THE BOUNDS BEFORE THE LIST: `analyzed: false` means nobody looked; `codeCoverage` says whether the app's own code was read at all, and in full; a non-empty `protectors` means the build is packed and its real code was never open to inspection. An empty `sdks` is only close to 'none' when `analyzed` is true and `codeCoverage` is `full`. Relay `summary` whole — it states the finding and its bound in one sentence, and dropping the second half is the standard way to get this wrong. ``` ### `list_similar_apps` - The name "list_similar_apps" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Apps related to one package — alternatives and neighbours, as the app's page on the site shows them. Free when there is nothing to list (an empty `items`). A package that is not in the catalogue is a 404 rather than a guess. ``` ### `list_trackers` - The name "list_trackers" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text The privacy question on its own: which advertising, analytics, install-attribution, crash-reporting, push and social sign-in SDKs are in this build, and nothing else. `list_sdks` is the same evidence unfiltered — every recognised library including HTTP clients and UI toolkits — so use that one when you want the full inventory and this one when somebody asked what an app sends about them. A CATEGORY IS NOT AN ACCUSATION: all six are ordinary parts of shipping an app, and `unclassified` counts recognised libraries that are neither (unclassified means we take no position, never that a library is harmless). READ THE BOUNDS BEFORE THE LIST: `analyzed: false` means nobody looked; `codeCoverage` says whether the app's own code was read at all and in full; a non-empty `protectors` means the real code was never readable, and an empty list under one says nothing about the app. Relay `summary` whole — 'no trackers found' without its second clause is the standard way to get this wrong. ``` ### `list_versions` - The name "list_versions" says "list": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Every APK/XAPK build held for a package, newest first, each with its SHA-256. Call this before get_download_url when you want a specific build — the apkId it returns is what that tool takes; without one it serves the newest. Free when we hold no builds for the package (an empty list); request_fetch is how to get the app. A package we will not serve at all is refused here with the same reason a download would give, so you learn it without spending a download. ``` ### `lookup_certificate` - The name "lookup_certificate" says "lookup": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Every package we hold that one signing certificate is on record for. Android only installs an update signed by the key that signed what is already on the device, which makes the signing key the closest thing an app has to an identity across package names — so a key you found on one repackaged app is worth asking about, because it has usually signed others. Takes the SHA-256 fingerprint of the DER certificate (64 hex, colons and case fine). A SHA-1 IS REFUSED, free, with the reason: the record stores one fingerprint per certificate and a SHA-1 cannot be resolved to it — get the SHA-256 (keytool prints both). BOUNDED, and `note` says how: it covers packages we have ingested and scanned, never every app the key has signed, so it is free when we hold nothing signed by the key (`total: 0`), which is not to say the key signs nothing; charged even when every package the key signed has been removed (an empty `items`). `blocked: true` means the key is on our catalogue-wide blocklist and nothing it signed can be downloaded here. Taken-down packages are counted in `blockedCount` and not listed, so a page may be shorter than `perPage`. ``` ### `lookup_hash` - The name "lookup_hash" says "lookup": a word for reading. - Tag private-data: The description's first sentence says "file": it reads files. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Which app and which build a file checksum names. Use this when you have a hash and no package name — an APK pulled off a device, a sample from a threat feed, a digest in an incident report. Takes an MD5 (32 hex), SHA-1 (40) or SHA-256 (64) and works out which from the length, so do not try to label it; colons, spaces and upper case are fine and are normalised. A miss is a real answer, not an error, and it is free when nothing matches (`found: false`): we hold no build with that checksum, and says nothing about whether the file exists elsewhere. READ `note`: only SHA-256 is carried by every stored build, so a SHA-1 or MD5 miss can mean we hold the file and never computed that digest for it — re-check with the SHA-256 if you have it. Once you have the packageName and apkId, the per-build tools will tell you what the file is. ``` ### `search_apps` - The name "search_apps" says "search": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Search the APK catalogue by name, publisher or package id. Start here when you have a phrase and need a package name. Returns 24 results a page out of at most 60 matches, so paging stops at page 3 — narrow the phrase rather than paging for more. `facets` counts the matches by type and category before filtering, so it tells you which filter would narrow a broad phrase. Searching an exact package id works as a lookup. A phrase nobody has searched before asks Google Play live and can take up to 20 seconds; UPSTREAM_UNAVAILABLE / UPSTREAM_BUSY there is refunded and means Play did not answer in time, not that nothing matches — retry the same phrase after a few seconds. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `apkcube`: ```json { "permissions": { "allow": [ "mcp__apkcube__search_apps", "mcp__apkcube__get_app", "mcp__apkcube__list_versions", "mcp__apkcube__get_fetch_status", "mcp__apkcube__get_variant_status", "mcp__apkcube__list_developer_apps", "mcp__apkcube__list_categories", "mcp__apkcube__list_chart", "mcp__apkcube__list_similar_apps", "mcp__apkcube__get_play_details", "mcp__apkcube__list_reviews", "mcp__apkcube__get_version_security", "mcp__apkcube__list_sdks", "mcp__apkcube__get_protection", "mcp__apkcube__list_trackers", "mcp__apkcube__list_permissions", "mcp__apkcube__get_manifest", "mcp__apkcube__get_raw_scan", "mcp__apkcube__lookup_hash", "mcp__apkcube__lookup_certificate", "mcp__apkcube__list_developer_certificates", "mcp__apkcube__get_signing_history", "mcp__apkcube__compare_versions", "mcp__apkcube__get_apps", "mcp__apkcube__get_account", "mcp__apkcube__console_list_apps", "mcp__apkcube__console_list_uploads" ], "ask": [ "mcp__apkcube__check_availability", "mcp__apkcube__get_download_url", "mcp__apkcube__request_fetch", "mcp__apkcube__request_variant", "mcp__apkcube__console_app_stats", "mcp__apkcube__console_upload_status", "mcp__apkcube__console_security_report" ], "deny": [ "mcp__apkcube__console_update_listing", "mcp__apkcube__console_set_version_notice" ] } } ``` Capability tags behind the rules (a read tagged outbound is asked about): - `mcp__apkcube__search_apps`: untrusted-input - `mcp__apkcube__get_app`: untrusted-input - `mcp__apkcube__check_availability`: untrusted-input - `mcp__apkcube__list_versions`: untrusted-input - `mcp__apkcube__get_download_url`: untrusted-input - `mcp__apkcube__request_fetch`: untrusted-input - `mcp__apkcube__get_fetch_status`: untrusted-input - `mcp__apkcube__request_variant`: untrusted-input - `mcp__apkcube__get_variant_status`: untrusted-input - `mcp__apkcube__list_developer_apps`: untrusted-input - `mcp__apkcube__list_chart`: untrusted-input - `mcp__apkcube__list_similar_apps`: untrusted-input - `mcp__apkcube__get_play_details`: private-data, untrusted-input - `mcp__apkcube__list_reviews`: untrusted-input - `mcp__apkcube__get_version_security`: untrusted-input - `mcp__apkcube__list_sdks`: untrusted-input - `mcp__apkcube__get_protection`: untrusted-input - `mcp__apkcube__list_trackers`: untrusted-input - `mcp__apkcube__list_permissions`: untrusted-input - `mcp__apkcube__get_manifest`: untrusted-input - `mcp__apkcube__get_raw_scan`: untrusted-input - `mcp__apkcube__lookup_hash`: private-data, untrusted-input - `mcp__apkcube__lookup_certificate`: untrusted-input - `mcp__apkcube__list_developer_certificates`: untrusted-input - `mcp__apkcube__get_signing_history`: untrusted-input - `mcp__apkcube__compare_versions`: untrusted-input - `mcp__apkcube__get_apps`: untrusted-input
