AI agents call cardsModTime to retrieve information from Anki without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns existing card metadata (modification timestamps). It performs no side effects, creates no new data, executes no code, and does not delete or move resources. It is purely a data retrieval operation consistent with the Read category.
From the tool's definition Tool name 'cardsModTime' and description 'Returns modification time for each card ID provided' indicate a retrieval operation that queries metadata without modifying or deleting data.
Documented attack patterns abuse exactly the kind of access cardsModTime gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Anki, and nothing reaches the server without passing your rules. This is the rule we recommend for cardsModTime:
{
"version": "1",
"default": "deny",
"tools": {
"cardsModTime": {}
}
}cardsModTime is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Returns modification time for each card ID provided. Result is a list of objects with. It is categorised as a Read tool in the Anki MCP Server, which means it retrieves data without modifying state.
Register the Anki MCP server in PolicyLayer and add a rule for cardsModTime: 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. Nothing to install.
cardsModTime 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 cardsModTime 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 cardsModTime. 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.
cardsModTime is provided by the Anki MCP server (ujisati/anki-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Anki, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
