Creates a note using the given deck and model, with the provided field values and tags. Returns the identifier of the created note created on success, and null on failure.
AI agents use add_note to create or update resources in Anki MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Anki MCP Server environment.
The tool creates new flashcard notes in Anki with specified content. This is a Write operation because it creates data reversibly—notes can be deleted or edited afterward. While it modifies the user's Anki deck, the blast radius is limited to the flashcard study system with no financial, destructive, or code execution implications.
From the tool's definition Tool description states it 'Creates a note' with field values and tags, returning a note identifier on success. This is a reversible creation operation.
Attacks that exploit this kind of access
Creates a note using the given deck and model, with the provided field values and tags. Returns the identifier of the created note created on success, and null on failure. It is categorised as a Write tool in the Anki MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Anki MCP Server MCP server in PolicyLayer and add a rule for add_note: 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 MCP Server. Nothing to install.
add_note 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_note 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_note. 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_note is provided by the Anki MCP Server MCP server (loonskai/anki-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
