Why colorize_point_cloud needs a policy

Colorization modifies the point cloud by adding color attributes to vertices/points, which represents a Write operation (creates or modifies data reversibly). While this is destructive in the sense that it overwrites the original point cloud's color state, it is reversible by re-running alignment or loading a previous state, so it does not meet the irreversible criteria for Destructive.

From the tool's definition The tool performs 'Colorize the dense point cloud' — a modification operation that processes and updates the point cloud data by applying color information derived from source imagery. This is a reversible transformation of existing data.

POLICY

How to control colorize_point_cloud

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 colorize_point_cloud:

policy.json

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

colorize_point_cloud 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about colorize_point_cloud

What does the colorize_point_cloud tool do? +

Colorize the dense point cloud from source imagery. 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 colorize_point_cloud? +

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

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

Can I rate-limit colorize_point_cloud? +

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

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

colorize_point_cloud 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.
