planka_list_cards
AI agents call planka_list_cards to retrieve information from Another Planka MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' operation retrieves and queries existing data without modifying or deleting anything. It has no side effects beyond returning information to the caller. The blast radius of misuse is minimal — an AI agent listing cards cannot cause harm beyond potentially reading information it shouldn't access, which is a confidentiality concern rather than integrity or availability impact.
