Why ai.sentiment is rated Low
This tool analyzes and classifies provided text to extract sentiment information, returning analysis results without modifying, deleting, or executing external operations. The POST method is used to submit text for analysis, but no data is created, modified, or destroyed—only read and classified. No code execution, financial transaction, or destructive action occurs. This is a pure analytical Read operation.
From the tool's definition POST { text }. Returns overall sentiment (positive/negative/neutral/mixed), a polarity score from -1 to 1, a confidence, and a one-line rationale.

The rule that runs ai.sentiment safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ai.sentiment, this is the rule to start with:
ai.sentiment is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp, apply this rule, and every ai.sentiment call is checked against it from then on.
