WHAT IT DOES

What list_mail does on FeatureBoard

AI agents call list_mail to retrieve information from FeatureBoard 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_mail is rated Low

This tool retrieves and queries existing mail data with optional filters. It performs no creation, modification, deletion, or external operations. The classification as Read is appropriate for a retrieval-only operation that merely displays mail history and drafts without altering them.

From the tool's definition Tool description states 'List mail (newest-first), optionally filtered by status (draft/sent) and/or company.' The verb 'list' and the filtering parameters indicate data retrieval with no modification or side effects.

RECOMMENDED RULE

The rule that runs list_mail safely

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

list_mail Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_mail": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect FeatureBoard, apply this rule, and every list_mail call is checked against it from then on.
