# set_cards_due_date A write tool on the Anki MCP server. Agent View of the PolicyLayer registry record for `set_cards_due_date`. HTML page: https://policylayer.com/tools/io-github-arielbk-anki-mcp/set-cards-due-date ## Facts - Tool: `set_cards_due_date` - Server: Anki (`@arielbk/anki-mcp`) — https://policylayer.com/tools/io-github-arielbk-anki-mcp.md - Install: `npx -y @arielbk/anki-mcp` - Homepage: https://github.com/arielbk/anki-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "set_cards_due_date", "arguments": {} } } ``` ## Why set_cards_due_date is rated Medium Setting due dates modifies card scheduling state in Anki reversibly—it changes when cards are next reviewed but does not delete data or execute arbitrary code. This is a Write operation (reversible modification). Severity is medium because incorrect due date changes could disrupt a user's study schedule, but the effect is correctable and doesn't cause data loss or financial impact. From the tool's own definition: "Tool name 'set_cards_due_date' indicates modification of card metadata (due dates); empty description limits full analysis but name clearly implies state change operation." ## Use case AI agents use set_cards_due_date 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
