WHAT IT DOES

What asc_post_alternative_distribution_key does on Appstoreconnect Mcp

AI agents use asc_post_alternative_distribution_key to create or update resources in Appstoreconnect Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Appstoreconnect Mcp environment.

RISK

Why asc_post_alternative_distribution_key is rated Medium

This tool creates/registers a new alternative distribution key in App Store Connect. The POST operation with 'register' language indicates it writes/creates a new security artifact (the public key) in the system. While it explicitly handles only the PUBLIC key (reducing risk vs. private key exposure), registration of cryptographic keys is a write operation that establishes trust for alternative distribution channels.

From the tool's definition POST /v1/alternativeDistributionKeys — register the PUBLIC key (PEM string)
