WHAT IT DOES

What chatter_post does on Odoo MCP Server

WHY IT NEEDS A POLICY

Why chatter_post needs a policy

Posting to Chatter creates new communication records reversibly (messages can be deleted/archived). This is a Write operation—it modifies data but doesn't destroy it permanently or execute arbitrary code. Severity is medium because unbounded chatter posts could spam the system or leak sensitive information through Odoo's collaborative messaging, but the blast radius is contained to communication artifacts.

From the tool's definition Tool name 'chatter_post' indicates posting to Odoo's Chatter (internal messaging/communication module). The 'post' action creates new messages/records in the system. Description is empty, limiting certainty.
