hsk_polyphones

List Chinese characters with multiple pronunciations (多音字) in HSK vocabulary. Each result includes all pronunciation forms with pinyin, meanings, and part of speech. Ordered by frequency. Paginated (20 per page).

Part of the Hsk MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call hsk_polyphones to retrieve information from Hsk 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 hsk_polyphones 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.

What does the hsk_polyphones tool do? +

List Chinese characters with multiple pronunciations (多音字) in HSK vocabulary. Each result includes all pronunciation forms with pinyin, meanings, and part of speech. Ordered by frequency. Paginated (20 per page).. It is categorised as a Read tool in the Hsk MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on hsk_polyphones? +

Add a rule in your Intercept YAML policy under the tools section for hsk_polyphones. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Hsk MCP server.

What risk level is hsk_polyphones? +

hsk_polyphones is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit hsk_polyphones? +

Yes. Add a rate_limit block to the hsk_polyphones rule in your Intercept 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.

How do I block hsk_polyphones completely? +

Set action: deny in the Intercept policy for hsk_polyphones. 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.

What MCP server provides hsk_polyphones? +

hsk_polyphones is provided by the Hsk MCP server (kuibin-dev/hsk-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
