List all flashcards in a specific deck
AI agents call list_cards to retrieve information from Anki MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing flashcard data without creating, modifying, deleting, or executing any operations. It is a straightforward read-only operation that poses minimal security risk. The only potential concern would be information disclosure if the deck contains sensitive data, but that is a low-severity information access risk, not a high-impact category.
From the tool's definition Tool name is 'list_cards' and description states 'List all flashcards in a specific deck' — a pure retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all flashcards in a specific deck. It is categorised as a Read tool in the Anki MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Anki MCP Server MCP server in PolicyLayer and add a rule for list_cards: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Anki MCP Server. Nothing to install.
list_cards is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_cards rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_cards. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_cards is provided by the Anki MCP Server MCP server (raghupalash/anki.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
