AI agents call opendosm_get_dataset to retrieve information from Opendosm My 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 opendosm_get_dataset 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 records from an official Malaysian statistics dataset (data.gov.my / OpenDOSM, Dept of Statistics Malaysia). Keyless, authoritative. The dataset id is REQUIRED — there is no listing endpoint, so use opendosm_list_datasets or opendosm_dataset_meta to discover ids and their columns. Verified high-value ids: cpi_headline (Headline Consumer Price Index, monthly (1980–present).); cpi_core (Core CPI (excludes volatile items), monthly.); gdp_qtr_real (Real GDP, quarterly (constant 2015 prices).); economic_indicators (Leading / coincident / lagging economic indicator indices, monthly.); ipi (Industrial Production Index, monthly (seasonally adjusted + absolute).); lfs_month (Labour force survey, monthly: unemployment rate, participation rate, employment.); fuelprice (Weekly retail fuel prices (RON95, RON97, diesel) in MYR per litre.); hh_income (Household income: mean and median (MYR), by survey year.); population_malaysia (Malaysia population by age / sex / ethnicity (thousands), annual.); population_state (Population by state, age, sex, ethnicity (thousands).); births (Live births by state and date.); deaths (Deaths: absolute count and crude rate, annual.). Filter syntax is value@column (e.g. filter="overall@division" keeps only rows where division=overall). Range syntax is column[start:end] on NUMERIC columns only, either bound optional (e.g. range="index[130:140]", range="index[135:]"). Date ranges are NOT supported by range; instead use sort="-date" with limit to get the most recent rows. sort="-col" is descending, sort="col" ascending.. It is categorised as a Read tool in the Opendosm My MCP Server, which means it retrieves data without modifying state.
Register the Opendosm My MCP server in PolicyLayer and add a rule for opendosm_get_dataset: 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 Opendosm My. Nothing to install.
opendosm_get_dataset 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 opendosm_get_dataset 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 opendosm_get_dataset. 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.
opendosm_get_dataset is provided by the Opendosm My MCP server (https://gateway.pipeworx.io/opendosm-my/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
