THE RISK

High Risk

Why calibrate_reflectance needs a policy

Based on the tool name alone, 'calibrate_reflectance' likely performs a calibration operation on multispectral or reflectance data within Agisoft Metashape, which is a processing/execution action. Without a description, confidence is low. Calibration typically modifies internal processing parameters, which fits Execute. Severity is medium given it could affect the accuracy of photogrammetry outputs if misapplied.

From the tool's definition Tool name: calibrate_reflectance; description is empty or uninformative.

POLICY

How to control calibrate_reflectance

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 calibrate_reflectance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "calibrate_reflectance": {
      "limits": [
        {
          "counter": "calibrate_reflectance_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

calibrate_reflectance stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about calibrate_reflectance

What does the calibrate_reflectance tool do? +

calibrate_reflectance. It is categorised as a Execute tool in the Metashape MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on calibrate_reflectance? +

Register the Metashape MCP Server MCP server in PolicyLayer and add a rule for calibrate_reflectance: 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 calibrate_reflectance? +

calibrate_reflectance is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit calibrate_reflectance? +

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

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

calibrate_reflectance 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.

Enforce policy on every Metashape MCP Server tool call.

Start from Metashape MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
