Search words and definitions in Anki deck
AI agents call search-words 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 performs a search operation to retrieve and display words and their definitions from an Anki deck. It has no side effects, does not create, modify, or delete data, and does not execute code or trigger external operations. It is a straightforward Read operation with minimal risk.
From the tool's definition Tool name 'search-words' and description 'Search words and definitions in Anki deck' indicate a query operation that retrieves data without modification.
Documented attack patterns abuse exactly the kind of access search-words 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 search-words:
{
"version": "1",
"default": "deny",
"tools": {
"search-words": {}
}
}search-words is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search words and definitions in Anki deck. 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 search-words: 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.
search-words 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 search-words 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 search-words. 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.
search-words is provided by the Anki MCP server (solidspoon/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.
