WHAT IT DOES

What extractTextFromImage does on API Ninjas

AI agents call extractTextFromImage 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
`image`	string	Yes	Image file to extract text from. Must be either JPEG or PNG format.

Parameters from the server's own tool schema.

RISK

Why extractTextFromImage is rated Low

Even though extractTextFromImage 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

RECOMMENDED RULE

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

extractTextFromImage Allowed

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

View as policy code

policy.json

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

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 extractTextFromImage call is checked against it from then on.
