Why export_bc3_budget needs a policy

The tool appears to export budget data, which constitutes data creation/generation rather than destructive deletion. Without a description, confidence is reduced, but the export pattern on this Blender/IFC server suggests it produces output files or structured data (Write category). It's not Destructive because exports typically do not irreversibly delete source data.

From the tool's definition Tool name 'export_bc3_budget' indicates creation/export of budget data in BC3 format (a standard construction cost format). Despite empty description, the 'export' verb combined with 'budget' in name suggests generating and writing structured data output.

POLICY

How to control export_bc3_budget

PolicyLayer is an MCP gateway — it sits between your AI agents and Bonsai-mcp, and nothing reaches the server without passing your rules. This is the rule we recommend for export_bc3_budget:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "export_bc3_budget": {
      "limits": [
        {
          "counter": "export_bc3_budget_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

export_bc3_budget 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 Bonsai-mcp — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
