WHAT IT DOES

What add_remote_mcp does on Obot Admin

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

WHY IT NEEDS A POLICY

Why add_remote_mcp needs a policy

This tool creates a new remote MCP server registration in the obot gateway, modifying the system's configuration state. It is reversible (can be deleted via delete_mcp_server sibling tool), so it qualifies as Write rather than Destructive.

From the tool's definition Tool description states 'Register a remote MCP server URL' and 'obot proxies it', indicating creation/addition of a new configuration entry in the gateway's registry. The name 'add_' prefix and verb 'register' confirm write semantics.
