send_mesh_message · MCP-Networkbot MCP: Risk & Policy

WHAT IT DOES

What send_mesh_message does on MCP-Networkbot

AI agents use send_mesh_message to create or update resources in MCP-Networkbot — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP-Networkbot environment.

WHY IT NEEDS A POLICY

Why send_mesh_message needs a policy

The tool creates/adds data (messages) to an existing conversation thread in a professional networking context. This is reversible (messages can typically be deleted or edited) and does not execute arbitrary code, delete data, or move money. Write category is appropriate.

From the tool's definition Tool description states it 'Send[s] a message to an existing Mesh Thread', which creates new message data in a group conversation. This is a write operation that modifies shared state by adding content to a thread.
