What getCars does on API Ninjas
AI agents call getCars 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 |
|---|---|---|---|
id | string | — | A car handle from a previous search, e.g. car_e71ff3416a. Safe to store: it is derived from the car's identity and survives data refreshes. |
ids | string | — | Comma-separated car handles, at most 50. Request order is preserved and a handle matching nothing is returned as null. |
body | string | — | Body style. One of Sedan, Coupe, Convertible, Wagon, Hatchback, Liftback, SUV, MPV, Van, Pickup. |
fuel | string | — | Fuel type. |
make | string | — | Manufacturer, as a word. Case and punctuation are ignored, so bmw, BMW and Bmw all resolve. |
sort | string | — | Sort order. |
year | integer | — | Cars in production in this year. A filter, not a starting point. |
badge | string | — | Model designation, e.g. 320d. Spacing and case are ignored. |
doors | integer | — | Number of doors. |
drive | string | — | Driven wheels. |
limit | integer | — | How many results to return, between 1 and 100. Default 10 -- each car carries a full specification sheet of roughly 2 KB. A value outside the range is rejected |
model | string | — | Model, as a word. '3 Series', '3-series' and '3series' all resolve. |

Why getCars is rated Low
Even though getCars 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 getCars 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 getCars, this is the rule to start with:
getCars 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 getCars call is checked against it from then on.
Questions about getCars
The main endpoint. Search the whole catalogue by any combination of filters, or fetch cars you already know with id/ids. Every car is returned with its complete specification sheet attached, so no second call is needed. Each row also carries its own make, model, generation, body and engine context. At least one filter, or an id, is required. The total number of matches is returned in the X-Total-Count response header. Requires a paid plan (Premium). It is categorised as a Read tool in the API Ninjas MCP Server, which means it retrieves data without modifying state.
getCars accepts 12 parameters: id, ids, body, fuel, make, sort, year, badge, doors, drive, limit, model. 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 getCars: 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.
getCars 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 getCars 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 getCars. 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.
getCars 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.
