List every party known to the participant via GET /v2/parties/known.
AI agents call canton_list_parties to retrieve information from Tenzro Ledger MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a list of known parties without modifying, executing external operations, deleting, or moving funds. It is a straightforward data retrieval endpoint that poses minimal risk even if misused by an AI agent, as it only exposes existing party information that is already known to the participant.
