What add_notes does on Anki
AI agents use add_notes 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 add_notes is rated Medium
This tool creates new data (flashcard notes) in the Anki system. Creation is reversible via deletion, so it falls under Write rather than Destructive. Severity is medium because an AI agent could add numerous low-quality or spam notes, cluttering a user's study deck, but the impact is recoverable and localized to the Anki system.
From the tool's definition Tool name 'add_notes' indicates creation of flashcard notes in Anki. Sibling tools include 'add_note' and context shows this is an Anki flashcard integration server. The description is empty, which lowers confidence slightly.
Attacks that exploit this kind of access
The rule that runs add_notes 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 add_notes, this is the rule to start with:
add_notes 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 add_notes call is checked against it from then on.
Questions about add_notes
add_notes 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 add_notes: 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.
add_notes 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 add_notes 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 add_notes. 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.
add_notes 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.
