evaluate_ttr
AI agents call evaluate_ttr to retrieve information from Aigc Humanizer Zh without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
TTR (Type-Token Ratio) is a standard text analysis metric that measures lexical diversity by comparing unique words to total words. The name 'evaluate_ttr' strongly suggests a read/analysis operation that computes a score from text without modifying anything. Given the server context of analyzing AI writing patterns in Chinese academic text, this tool likely reads and evaluates text properties.
From the tool's definition Tool name 'evaluate_ttr' suggests evaluation/measurement (TTR = Type-Token Ratio, a text analysis metric). Description is empty.
Attacks that exploit this kind of access
evaluate_ttr. It is categorised as a Read tool in the Aigc Humanizer Zh MCP Server, which means it retrieves data without modifying state.
Register the Aigc Humanizer Zh MCP server in PolicyLayer and add a rule for evaluate_ttr: 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 Aigc Humanizer Zh. Nothing to install.
evaluate_ttr 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 evaluate_ttr 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 evaluate_ttr. 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.
evaluate_ttr is provided by the Aigc Humanizer Zh MCP server (shuohui-air-technology/aigc-humanizer-zh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
