WHAT IT DOES

What wallet_revealCounterpartyKeyLinkage does on Bitcoin SV MCP Server

AI agents call wallet_revealCounterpartyKeyLinkage to retrieve information from Bitcoin SV 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 wallet_revealCounterpartyKeyLinkage is rated Low

The tool reveals (reads/discloses) cryptographic key linkage information between wallet identities. This is a read/disclosure operation, not a write or destructive one. However, severity is high because exposing identity linkage on a blockchain is a significant privacy risk — it could permanently de-anonymize wallet relationships, and once revealed to a verifier, that disclosure cannot be undone.
