THE RISK

Medium Risk

Why odoo_attachment_upload needs a policy

This tool creates new attachment records in Odoo by uploading files. This is a Write operation (creates reversible data structures). Severity is medium because: (1) attachments can be deleted/modified later, (2) blast radius is limited to file storage and record metadata, (3) no destructive deletion occurs, (4) no financial impact.

From the tool's definition Tool name 'odoo_attachment_upload' and description 'Upload a file as an ir.attachment on an Odoo record' indicate file creation/attachment to existing records.

POLICY

How to control odoo_attachment_upload

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

policy.json

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

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