AI agents call get_drug_overdose_deaths to retrieve information from CDC Mortality (WONDER) 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 get_drug_overdose_deaths 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.

Get provisional drug overdose death data by state. Returns provisional counts and rates of drug overdose deaths from the National Vital Statistics System (NVSS). Includes data on opioid, synthetic opioid, and other drug-involved deaths. Updated monthly. Args: state: Filter by state name (e.g. 'West Virginia', 'Ohio'). Case-insensitive. Returns all states if not specified. year: Filter by year. Returns all available years if not specified. limit: Maximum number of records to return (default 25, max 1000).. It is categorised as a Read tool in the CDC Mortality (WONDER) MCP Server, which means it retrieves data without modifying state.
Register the CDC Mortality (WONDER) MCP server in PolicyLayer and add a rule for get_drug_overdose_deaths: 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 CDC Mortality (WONDER). Nothing to install.
get_drug_overdose_deaths 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 get_drug_overdose_deaths 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 get_drug_overdose_deaths. 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.
get_drug_overdose_deaths is provided by the CDC Mortality (WONDER) MCP server (https://mcp.olyport.com/cdc-wonder/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
