WHAT IT DOES

What get_migration_attestation_key does on Sanka MCP Server

AI agents call get_migration_attestation_key to retrieve information from Sanka MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_migration_attestation_key is rated Low

Even though get_migration_attestation_key only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access
