AI agents call censtatd_get_table to retrieve information from Censtatd Hk 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 censtatd_get_table 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.

Fetch a Hong Kong Census & Statistics Department statistical table as structured JSON (time series of {period, sv (measure), svDesc, figure} plus any dimension code/Desc columns). By default returns the FULL series (full_series=1) — reliable and keyless, no encoded param needed. Use this for HK GDP, employment earnings, trade, prices, money/financial-market stats, etc. Table ids look like '310-31001' (GDP) or '340-46001' (exchange rates); find ids with censtatd_search_tables. Optionally pass param — the opaque lz-string blob copied from the table's API Example box on censtatd.gov.hk — to fetch a filtered subset instead of the full series (we cannot generate this blob for you).. It is categorised as a Read tool in the Censtatd Hk MCP Server, which means it retrieves data without modifying state.
Register the Censtatd Hk MCP server in PolicyLayer and add a rule for censtatd_get_table: 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 Censtatd Hk. Nothing to install.
censtatd_get_table 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 censtatd_get_table 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 censtatd_get_table. 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.
censtatd_get_table is provided by the Censtatd Hk MCP server (https://gateway.pipeworx.io/censtatd-hk/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
