move_layer_to_group · QGIS MCP: Risk & Policy

WHAT IT DOES

What move_layer_to_group does on QGIS MCP

AI agents use move_layer_to_group to create or update resources in QGIS MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your QGIS MCP environment.

WHY IT NEEDS A POLICY

Why move_layer_to_group needs a policy

The tool restructures project metadata (layer organization) rather than deleting data or executing arbitrary code. While it modifies project state, the operation is fully reversible—layers can be moved to different groups or back to the root. This fits the Write category (modifies data reversibly).

From the tool's definition Tool name 'move_layer_to_group' and description indicate it modifies the organizational structure of layers within a QGIS project by moving/reorganizing them into groups. This is a reversible modification operation.

Verdict

move_layer_to_group Rate-limited

move_layer_to_group 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.

FAQ

Questions about move_layer_to_group

What does the move_layer_to_group tool do? +

Move a layer into a layer group by group name. It is categorised as a Write tool in the QGIS MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on move_layer_to_group? +

Register the QGIS MCP server in PolicyLayer and add a rule for move_layer_to_group: 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 QGIS MCP. Nothing to install.

What risk level is move_layer_to_group? +

move_layer_to_group is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit move_layer_to_group? +

Yes. Add a rate_limit block to the move_layer_to_group 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.

How do I block move_layer_to_group completely? +

Set action: deny in the PolicyLayer policy for move_layer_to_group. 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.

What MCP server provides move_layer_to_group? +

move_layer_to_group is provided by the QGIS MCP server (nkarasiak/qgis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
