THE RISK

Medium Risk

Why import_cameras needs a policy

This tool creates or modifies camera metadata within the Metashape project. While it doesn't irreversibly destroy data (Destructive) or execute arbitrary code (Execute), it does write new data to the photogrammetry project. The severity is medium because misuse could corrupt or override legitimate camera calibration data, but the effects are reversible and don't expose financial or external execution risks.

From the tool's definition 'Import camera positions and orientations from file' modifies project state by adding camera data, which is reversible through undo or deletion.

POLICY

How to control import_cameras

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 import_cameras:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "import_cameras": {
      "limits": [
        {
          "counter": "import_cameras_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

import_cameras 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.

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 import_cameras

What does the import_cameras tool do? +

Import camera positions and orientations from file. It is categorised as a Write tool in the Metashape MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on import_cameras? +

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

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

Can I rate-limit import_cameras? +

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

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

import_cameras 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.
