Why build_texture needs a policy

Texture building in photogrammetry is a computationally intensive operation that generates or modifies model data. While not inherently destructive (textures can be regenerated), it triggers external processing that modifies project state and outputs.

From the tool's definition Tool name 'build_texture' with empty description on Metashape MCP server. Based on sibling tools (build_contours, align_cameras, align_chunks) which perform computational photogrammetry operations, build_texture is inferred to execute texture…

POLICY

How to control build_texture

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 build_texture:

policy.json

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

build_texture 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 build_texture

What does the build_texture tool do? +

build_texture. 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 build_texture? +

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

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

Can I rate-limit build_texture? +

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

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

build_texture 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.
