AI agents call tone_score to retrieve information from Toolora MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though tone_score only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Score a text on four tone dimensions in one call: formal, casual, technical, urgent (each 0–1). Returns the dominant tone label plus the underlying signal counts (contractions, passive verbs, first/second-person pronouns, code blocks, brackets, exclamations, ALL-CAPS words, urgency keywords). Use this to check whether agent-generated copy matches the intended voice before sending — e.g. a customer-support reply should not score high on 'formal' or 'urgent'.. It is categorised as a Read tool in the Toolora MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Toolora MCP Server MCP server in PolicyLayer and add a rule for tone_score: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Toolora MCP Server. Nothing to install.
tone_score is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the tone_score rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for tone_score. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
tone_score is provided by the Toolora MCP Server MCP server (https://toolora.dev/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
