WHAT IT DOES

What get_capability_attestations does on Tenzro Ledger MCP

There are no indicators of data modification, execution of arbitrary code, deletion, or financial operations. The low severity reflects minimal blast radius if misused—an AI agent could only retrieve existing attestation metadata.
