Why odoo_message_post needs a policy

This tool creates/writes new data (messages) on Odoo records via the chatter system. The impact is reversible (messages can typically be deleted or marked as archived in Odoo), making it Write rather than Destructive.

From the tool's definition The tool 'posts' a message, and the description states it can 'post a message or internal note on any Odoo record (chatter).' Posting creates new message records that persist in the system.

POLICY

How to control odoo_message_post

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_message_post:

policy.json

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

odoo_message_post 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.
