What set_card_specific_values does on Anki
AI agents use set_card_specific_values to create or update resources in Anki, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Anki environment.
Why set_card_specific_values is rated Medium
The tool modifies card state (settings/values) rather than irreversibly deleting data or executing arbitrary code. Setting card properties in Anki is typically reversible through subsequent operations. Without explicit description confirming destructive or execute-level capabilities, Write is the most appropriate category. Severity is medium due to potential for mass modification of study data if misused by an agent.
From the tool's definition Tool name 'set_card_specific_values' indicates modification of card properties. Empty description limits certainty, but the verb 'set' combined with sibling tools like 'add_note', 'add_tags_to_notes', and 'answer_cards' suggests reversible data updates within…
Attacks that exploit this kind of access
The rule that runs set_card_specific_values safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Anki, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_card_specific_values, this is the rule to start with:
set_card_specific_values 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Anki, apply this rule, and every set_card_specific_values call is checked against it from then on.
Questions about set_card_specific_values
set_card_specific_values is a write tool on the Anki MCP server. It is categorised as a Write tool in the Anki MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Anki MCP server in PolicyLayer and add a rule for set_card_specific_values: 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.
set_card_specific_values 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 set_card_specific_values 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 set_card_specific_values. 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.
set_card_specific_values is provided by the Anki MCP server (@arielbk/anki-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
