Retrieve all layers in the current project.
AI agents call get_layers to retrieve information from QGISMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists data (layers in a QGIS project) without creating, modifying, deleting, or executing any operations. It is a pure read operation analogous to a database SELECT query. The blast radius of misuse is minimal—exposure of project structure poses no direct harm compared to write or execute tools on this server.
From the tool's definition Tool name 'get_layers' and description 'Retrieve all layers in the current project' indicate a query operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access get_layers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and QGISMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_layers:
{
"version": "1",
"default": "deny",
"tools": {
"get_layers": {}
}
}get_layers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Retrieve all layers in the current project. It is categorised as a Read tool in the QGISMCP MCP Server, which means it retrieves data without modifying state.
Register the QGIS MCP server in PolicyLayer and add a rule for get_layers: 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 QGISMCP. Nothing to install.
get_layers is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_layers 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 get_layers. 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.
get_layers is provided by the QGIS MCP server (syauqi-uqi/qgis_mcp_modify1). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from QGISMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
