Find cards using a raw Anki search query. Returns detailed card information including fields.
AI agents call find_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 retrieves and queries card data from Anki without creating, modifying, or deleting any information. It is a pure read operation that has no irreversible effects on the flashcard system. Even with arbitrary search query input, the worst-case impact is exposure of existing card data, which is a low-severity information disclosure rather than a destructive or financial risk.
From the tool's definition Tool name is 'find_cards' and description states it 'Find cards using a raw Anki search query. Returns detailed card information' — the verb 'find' and 'returns' indicate retrieval/querying with no modification or side effects.
Documented attack patterns abuse exactly the kind of access find_cards gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Anki MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for find_cards:
{
"version": "1",
"default": "deny",
"tools": {
"find_cards": {}
}
}find_cards is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find cards using a raw Anki search query. Returns detailed card information including fields. 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 find_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.
find_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 find_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 find_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.
find_cards is provided by the Anki MCP Server MCP server (nietus/anki-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
