WHAT IT DOES

What send_broadcast does on instantKOM MCP Server

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

RISK

Why send_broadcast is rated Medium

Sending a broadcast/newsletter delivers messages to potentially large numbers of contacts immediately. This is a Write operation (creating and dispatching messages), but not purely destructive or financial. The high severity reflects the blast radius: an AI agent misusing this tool could send unsolicited or harmful messages to a large audience, damaging reputation and user trust.

From the tool's definition 'Send a newsletter immediately' — triggers an outbound message broadcast to recipients

RECOMMENDED RULE

The rule that runs send_broadcast safely

PolicyLayer is an MCP gateway: it sits between your AI agents and instantKOM MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For send_broadcast, this is the rule to start with:

send_broadcast Rate-limited

send_broadcast 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.
