What getRandomImage does on API Ninjas
AI agents call getRandomImage 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 |
|---|---|---|---|
width | integer | — | Width of the image to generate. Must be between 1 and 5000. Default value is 640. Premium only. |
height | integer | — | Height of the image to generate. Must be between 1 and 5000. Default value is 480. Premium only. |
category | string | — | Image category. If set, must be one of the following: nature, city, technology, food, still_life, abstract, wildlife. Premium only. |
Parameters from the server's own tool schema.
Why getRandomImage is rated Low
Even though getRandomImage 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 getRandomImage 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 getRandomImage, this is the rule to start with:
getRandomImage 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 getRandomImage call is checked against it from then on.
Questions about getRandomImage
Returns a random royalty-free image, optionally constrained by category, width and height. Useful for placeholder or sample imagery. It is categorised as a Read tool in the API Ninjas MCP Server, which means it retrieves data without modifying state.
getRandomImage accepts 3 parameters: width, height, category. 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 getRandomImage: 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.
getRandomImage 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 getRandomImage 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 getRandomImage. 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.
getRandomImage 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.
