What is app-store-operator CLAUDE.md?

A set of project instructions for an MCP server that gives coding agents tools for researching competing apps in Apple's App Store. MCP is a standard way for an AI client to call tools provided by another server.

Use it when developing or maintaining the server, adding or changing its App Store research tools, understanding its scraping and caching code, or running its smoke test.

It gives contributors one reference for how the server is structured, how its tools are registered, and how to test changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.05633	$0.05633
Opus 5	$0.02816	$0.02816
Sonnet 5	$0.01127	$0.01127
Haiku 4.5	$0.00563	$0.00563

Security

Grade A, and why

app-store-operator CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

App Store Operator — MCP Server

This project is an MCP server that provides App Store competitive intelligence tools.

Two audiences for this file: the Codebase section below is for working on this repo; the MCP Tools section is for clients calling the published server.

Codebase

Plain ESM Node ("type": "module"), no build step, no linter, no transpiler. Node ≥ 18. The only test is a stdio smoke test (npm run smoke).

Three runtime dependencies, and each one is load-bearing:

@modelcontextprotocol/sdk — the low-level Server class plus raw request schemas, not the McpServer helper. Handlers are registered by schema in src/index.js.
playwright — drives the SensorTower scrape. Installed browsers are the reason postinstall exists.
app-store-scraper — App Store keyword search.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
