AI agents call get_deck_names 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 lists existing data (deck names) without side effects. It performs a query-like operation typical of Read category tools. No data is created, modified, deleted, or executed. Severity is low because listing deck names poses minimal security risk even if accessed without authorization, as it reveals only organizational metadata.
From the tool's definition Tool name is 'get_deck_names' and description states 'Get a list of all Anki deck names' — a straightforward retrieval operation with no modification, deletion, or execution.

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 get_deck_names:
{
"version": "1",
"default": "deny",
"tools": {
"get_deck_names": {}
}
}get_deck_names is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a list of all Anki deck names. 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 get_deck_names: 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.
get_deck_names 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 get_deck_names 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 get_deck_names. 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.
get_deck_names 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.
