Get infant mortality rates by state and race/ethnicity. Returns infant mortality data including rates per 1,000 live births, broken down by state and race/ethnicity. Infant mortality is a key indicator of community health status used in CHNAs. Args: state: Filter by state name (e.g. 'Ohio', 'Geor...

AI agents call get_infant_mortality 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_infant_mortality 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 infant mortality rates by state and race/ethnicity. Returns infant mortality data including rates per 1,000 live births, broken down by state and race/ethnicity. Infant mortality is a key indicator of community health status used in CHNAs. Args: state: Filter by state name (e.g. 'Ohio', 'Georgia'). Case-insensitive. Returns all states if not specified. year: Filter by year. Returns all available years if not specified.. 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_infant_mortality: 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_infant_mortality 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_infant_mortality 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_infant_mortality. 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_infant_mortality 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.
