Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security81
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 521, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- 57% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Partial
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 3641 tokens (~130/item across 28 items; 14 tools + 14 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
- Supports UI / widget rendering.Pass
How do I install the com.appskyline/appskyline MCP server?
com.appskyline/appskyline is a hosted endpoint at https://mcp.appskyline.com/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.

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 →
add_keyword Add tracked keyword ~109
Add a new tracked keyword to an Appskyline app after explicit confirmation. This modifies the tracked set and is non-idempotent: calling with the same term twice creates two keyword rows.
| Name | Type | Req | Description |
|---|---|---|---|
| appId | string | yes | Appskyline app id to attach the keyword to |
| country | string | – | Two-letter country code (e.g. US) |
| language | string | – | Two-letter language code (e.g. en) |
| searchTerms | string | yes | The keyword phrase to track |
| Name | Type | Req | Description |
|---|---|---|---|
| keyword | object | yes | – |
| status | string | yes | – |
No examples provided.
delete_keyword Delete tracked keyword ~67
Permanently delete a tracked Appskyline keyword by id. Idempotent — deleting an already-deleted keyword is a no-op. This stops collecting new ranking snapshots; historical search rows in the *-searches collections are not affected.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Keyword id to delete |
| Name | Type | Req | Description |
|---|---|---|---|
| keywordId | string | yes | – |

Summarize downloads, installs, uninstalls, crashes and other engagement totals reported by a store for one Appskyline app over a date window. Returns the aggregate totals, the most recent daily rows, and the top territories. Metric names differ per store because each store reports its own set.

get_keyword_overview Get keyword search-volume overview ~130
Look up monthly search volume, keyword difficulty, CPC and competition level for up to 50 search terms in one country. Values come from Appskyline's shared DataForSEO cache; terms missing or stale in the cache trigger a live, billable upstream lookup, so batch terms rather than calling once per keyword.

Read the store-listing metadata Appskyline has synced for one of your apps — per locale name, subtitle, keywords (with their character count against Apple's 100-character limit), promotional text, release notes, version and review state. Read-only: it never downloads from or uploads to the store.

What is the com.appskyline/appskyline MCP server?
com.appskyline/appskyline is an MCP server listed in the public MCP registry as com.appskyline/appskyline. Track app-store rankings, history, listing metadata, reviews and competitors across four stores. This page covers its hosted endpoint (https://mcp.appskyline.com/mcp).
Is the com.appskyline/appskyline MCP server safe to use?
com.appskyline/appskyline scores 85 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 com.appskyline/appskyline MCP server expose?
com.appskyline/appskyline exposes 14 tools: list_apps, get_app, list_keywords, search_store_results, get_keyword_rank, and 9 more. Their descriptions and schemas cost roughly 1,487 tokens of context every time the server is loaded.
Does the com.appskyline/appskyline MCP server require authentication?
Yes. com.appskyline/appskyline 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 com.appskyline/appskyline MCP server still maintained?
com.appskyline/appskyline is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
