MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Anki MCP Data Bridge tools

Destructive · High delete_cards This tool irreversibly removes flashcard data from the user's Anki collection. Destructive · High delete_deck This tool permanently removes deck data and potentially associated cards from Anki, which cannot be undone. Write · Medium remove_tags_from_cards Removing tags from cards modifies existing data (the tags associated with cards), but it is a reversible operation since tags can be re-added. Write · Low add_tags_to_cards This tool modifies card metadata (tags) in a reversible manner.

12 of Anki MCP Data Bridge's 18 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Anki MCP Data Bridge

PolicyLayer is an MCP gateway — it sits between your AI agents and Anki MCP Data Bridge, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "delete_cards": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "add_tags_to_cards": {
    "limits": [
      {
        "counter": "add_tags_to_cards_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_card_data": {
    "limits": [
      {
        "counter": "get_card_data_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Anki MCP Data Bridge

Can an AI agent delete data through the Anki MCP Data Bridge MCP server? +

Yes. The Anki MCP Data Bridge server exposes 2 destructive tools including delete_cards, delete_deck. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Anki MCP Data Bridge? +

The Anki MCP Data Bridge server has 10 write tools including add_tags_to_cards, create_card, create_cards_batch. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Anki MCP Data Bridge.

How many tools does the Anki MCP Data Bridge MCP server expose? +

18 tools across 3 categories: Destructive, Read, Write. 6 are read-only. 12 can modify, create, or delete data.

How do I enforce a policy on Anki MCP Data Bridge? +

Register the Anki MCP Data Bridge MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Anki MCP Data Bridge tool call.

Deterministic rules across all 18 Anki MCP Data Bridge tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
