AI agents call chinese.detect to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure query/analysis tool that examines text properties and returns classification results. It retrieves information about text characteristics without creating, modifying, or destroying data. The explicitly stated 'Deterministic, keyless' nature further confirms it performs only read operations. Low severity because misuse would only return incorrect classifications with no system impact.
From the tool's definition Tool performs text analysis only: 'Detect Chinese in text', 'counts', 'script classification'. No data modification, deletion, or external state changes. Deterministic analysis with no side effects.
Attacks that exploit this kind of access
Detect Chinese in text: whether it contains Han characters, how many, total length, and a script classification — simplified, traditional, mixed, or han-common (characters identical in both scripts). Deterministic, keyless. Route text to the right pipeline or pick a conversion direction before calling chinese.convert. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for chinese.detect: 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 Mcp. Nothing to install.
chinese.detect 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 chinese.detect 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 chinese.detect. 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.
chinese.detect is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
