Changes the order (index) of a field in a note type.
AI agents use reposition_note_type_field 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.
This tool modifies the configuration of a note type by reordering its fields. This is a Write operation because it changes existing data (field order) in a reversible manner. While it could potentially affect card generation or rendering if field order is relied upon by templates, the operation itself is not destructive (fields are not deleted) and does not execute arbitrary code or trigger external operations.
From the tool's definition Tool explicitly 'Changes the order (index) of a field in a note type'—modifying the structural arrangement of a note type's fields, which is a reversible modification of data.
Documented attack patterns abuse exactly the kind of access reposition_note_type_field gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Anki MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for reposition_note_type_field:
{
"version": "1",
"default": "deny",
"tools": {
"reposition_note_type_field": {
"limits": [
{
"counter": "reposition_note_type_field_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}reposition_note_type_field 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.

Changes the order (index) of a field in a note type. 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 reposition_note_type_field: 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.
reposition_note_type_field 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 reposition_note_type_field 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 reposition_note_type_field. 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.
reposition_note_type_field is provided by the Anki MCP Server MCP server (nietus/anki-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
