WHAT IT DOES

What getJoke does on API Ninjas

AI agents call getJoke 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
`limit`	integer	—	How many jokes to return. Must be between 1 and 100. Default is 1.

Parameters from the server's own tool schema.

RISK

Why getJoke is rated Low

Even though getJoke 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.

RECOMMENDED RULE

The rule that runs getJoke 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 getJoke, this is the rule to start with:

getJoke Allowed

getJoke is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "getJoke": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect API Ninjas, apply this rule, and every getJoke call is checked against it from then on.
