WHAT IT DOES

What list-sent-messages does on Frontmcp

AI agents call list-sent-messages to retrieve information from Frontmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list-sent-messages is rated Low

This tool queries and returns historical message data without altering, deleting, or executing any operations. The explicit mention '(for testing)' reinforces that it is a read-only diagnostic tool. The blast radius of misuse is minimal—an agent could access message history but cannot create, modify, delete, or trigger financial/destructive actions.

From the tool's definition Tool name 'list-sent-messages' and description 'List all messages sent through the messaging service' indicate a retrieval operation with no modification or side effects.

RECOMMENDED RULE

The rule that runs list-sent-messages safely

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

list-sent-messages Allowed

list-sent-messages is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-sent-messages": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every list-sent-messages call is checked against it from then on.
