What getNaics does on API Ninjas
AI agents call getNaics to retrieve information from API Ninjas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
code | string | — | NAICS code, 2 to 6 digits. Required unless title is provided. |
year | string | — | NAICS revision. Currently 2022 only; NAICS 2027 is not published by the Census Bureau until January 2027. |
codes | string | — | Comma-separated NAICS codes for batch lookup. Maximum 50 on Developer, 500 on Business and above. |
title | string | — | Look up by official title. Supports partial matching. |
country | string | — | Currently US only. NAICS Canada and SCIAN Mexico are not yet available. |
crosswalk_to | string | — | Also map the code to an earlier NAICS revision. Currently 2017 only. The Census concordance covers 6-digit national industries. |
Parameters from the server's own tool schema.
Why getNaics is rated Low
Even though getNaics only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access
The rule that runs getNaics safely
PolicyLayer is an MCP gateway: it sits between your AI agents and API Ninjas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getNaics, this is the rule to start with:
getNaics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect API Ninjas, apply this rule, and every getNaics call is checked against it from then on.
Questions about getNaics
Returns the official title, description, full hierarchy, index terms and cross-references for a NAICS code. Pass crosswalk_to to also map the code to another NAICS revision or to SIC. Available on all plans. It is categorised as a Read tool in the API Ninjas MCP Server, which means it retrieves data without modifying state.
getNaics accepts 6 parameters: code, year, codes, title, country, crosswalk_to. The full parameter table on this page comes from the server's own tool schema.
Register the API Ninjas MCP server in PolicyLayer and add a rule for getNaics: 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 API Ninjas. Nothing to install.
getNaics 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 getNaics 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 getNaics. 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.
getNaics is provided by the API Ninjas MCP server (https://mcp.api-ninjas.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
