WHAT IT DOES

What send_test_sms does on Sequenzy Mcp

AI agents invoke send_test_sms to trigger actions in Sequenzy Mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why send_test_sms is rated High

This tool triggers an external operation (sending a real SMS message) and consumes SMS credits. While it has a financial cost component (charges SMS credits), it does not directly move money or commit financial obligations in the traditional sense — it consumes a pre-purchased credit balance.

From the tool's definition Send a test SMS to a phone number. IMPORTANT: sends a real text message and charges SMS credits - only call when the user explicitly asks for a test send.

RECOMMENDED RULE

The rule that runs send_test_sms safely

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

send_test_sms Rate-limited

send_test_sms stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
