Create a new cloze deletion card in a specified deck. Use {{c1::text}} syntax for cloze deletions.
AI agents use create-cloze-card to create or update resources in Clanki — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Clanki environment.
This tool creates new flashcard data within an Anki deck. Creation of data is a Write operation. The severity is low because: (1) flashcard creation is reversible (cards can be deleted), (2) the blast radius is limited to personal study material with no external dependencies, (3) no financial, destructive, or code execution side effects are possible, and (4) misuse would only affect the user's own flashcard…
From the tool's definition Tool description states 'Create a new cloze deletion card in a specified deck', indicating creation of a new data structure (flashcard) within the Anki system.
Documented attack patterns abuse exactly the kind of access create-cloze-card gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Clanki, and nothing reaches the server without passing your rules. This is the rule we recommend for create-cloze-card:
{
"version": "1",
"default": "deny",
"tools": {
"create-cloze-card": {
"limits": [
{
"counter": "create-cloze-card_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create-cloze-card stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Create a new cloze deletion card in a specified deck. Use {{c1::text}} syntax for cloze deletions. It is categorised as a Write tool in the Clanki MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Clanki MCP server in PolicyLayer and add a rule for create-cloze-card: 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 Clanki. Nothing to install.
create-cloze-card is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create-cloze-card 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 create-cloze-card. 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.
create-cloze-card is provided by the Clanki MCP server (jasperket/clanki). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Clanki, 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.
