What list_sensors does on Metashape MCP Server

AI agents call list_sensors to retrieve information from Metashape MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_sensors needs a policy

This tool performs a read-only query of sensor metadata from the active chunk in Metashape. It retrieves calibration details for informational purposes only, with no side effects, data modification, code execution, or destructive capabilities. This is a straightforward data retrieval operation typical of Read category tools.

From the tool's definition Tool name 'list_sensors' and description 'List all sensors in the active chunk with calibration details' indicate a query operation that retrieves and displays sensor information without modifying or executing any operations.

How to control list_sensors

PolicyLayer is an MCP gateway — it sits between your AI agents and Metashape MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_sensors:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_sensors": {}
  }
}

list_sensors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Metashape MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on list_sensors? +

Register the Metashape MCP Server MCP server in PolicyLayer and add a rule for list_sensors: 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 Metashape MCP Server. Nothing to install.

What risk level is list_sensors? +

list_sensors is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_sensors? +

Yes. Add a rate_limit block to the list_sensors 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 list_sensors completely? +

Set action: deny in the PolicyLayer policy for list_sensors. 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 list_sensors? +

list_sensors is provided by the Metashape MCP Server MCP server (jenkinsm13/metashape-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
