Why match_photos needs a policy

Based on the server context (Agisoft Metashape photogrammetry automation) and the tool name, 'match_photos' likely triggers the photo matching/feature detection process, which is a computational operation that runs processing on loaded images. This falls under Execute as it triggers an external operation. Confidence is low due to empty description.

From the tool's definition Tool name 'match_photos' on a photogrammetry server; description is empty and uninformative.

POLICY

How to control match_photos

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 match_photos:

policy.json

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

match_photos 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.
