What is appstoreconnect-mcp AGENTS.md?

Project instructions for an MCP server that connects agents to App Store Connect, Apple’s service for managing apps and store listings. They cover building, running, credentials, diagnostics, and the server’s tool structure.

Building the Swift server, running its diagnostic check, configuring Apple API credentials, and understanding how its App Store Connect tools receive and handle requests.

They explain how to build and start the server and which credentials are required, reducing setup and authentication errors.

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	$0.00596	$0.00596
Opus 5.5	$0.00238	$0.00238

Security

Grade A, and why

appstoreconnect-mcp AGENTS.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 2mo 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.

AGENTS.md — App Store Connect MCP

Build

swift build

Build output: .build/debug/appstoreconnect-mcp

Release build:

swift build -c release

Build output: .build/release/appstoreconnect-mcp

Run

Standard MCP stdio mode — the binary reads/writes JSON over stdin/stdout. No other config.

Diagnostic test (reports credential/API/link health):

<build-output>/MyTool --test

Interactive fallback prompts if env vars are missing.

Credentials (required at runtime)

Env var	Description
`APP_STORE_CONNECT_ISSUER_ID`	UUID from API Keys page
`APP_STORE_CONNECT_PRIVATE_KEY_ID`	10-char Key ID
`APP_STORE_CONNECT_PRIVATE_KEY_PATH`	Path to `.p8` file
or `APP_STORE_CONNECT_PRIVATE_KEY`	Raw PEM key content

Architecture

Entrypoint: Sources/appstoreconnect-mcp/main.swift — --test flag runs diagnostics; otherwise starts MCP server on StdioTransport.
Tool definitions: Sources/appstoreconnect-mcp/Tools/ToolDefinitions.swift — 25 tools in ToolDefinitions.allTools.
Handler dispatch: Sources/appstoreconnect-mcp/Tools/ToolHandlers.swift — decode args → call ASCClient → return CallTool.Result.
API layer: Sources/appstoreconnect-mcp/ASCClient.swift — wraps APIProvider from AppStoreConnect-Swift-SDK (v4.4.1) with per-request instantiation.
Credentials: Sources/appstoreconnect-mcp/Credentials.swift — loadFromEnvironment() reads env vars, supports .p8 file or inline PEM string.
Utils: Sources/appstoreconnect-mcp/Utils/JSONUtils.swift — pretty-print JSON, decode MCP Value dicts.
Transport: StdioTransport via mcp-swift-sdk (v0.12.1). Server idle-keeps via Task.sleep(nanoseconds: UInt64.max).

Key constraints

SwiftPM package — Package.swift at root. Use swift build to compile.
Swift 6 warnings — RunLoop.current.run() in --test path (async context) and deprecated .text(...) API in handlers are pre-existing; avoid "fixing" them without explicit request.
No tests, no CI, no linter config in this repo.
Adding a new tool requires editing 3 files: ToolDefinitions.swift (schema), ToolHandlers.swift (handler), ASCClient.swift (API method).

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.
