AI agents call ocr_image to retrieve information from Noapi Google Search without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
OCR (optical character recognition) processes images to extract text—a retrieval and querying operation with no side effects on the source image or system state. While it requires processing resources, it does not create, modify, delete, or execute code. It falls clearly into the Read category.
From the tool's definition Tool name 'ocr_image' indicates optical character recognition on images, which extracts/retrieves text content from image files. The broader server description mentions 'OCR' as part of its retrieval capabilities alongside search and feeds.
Documented attack patterns abuse exactly the kind of access ocr_image gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Noapi Google Search, and nothing reaches the server without passing your rules. This is the rule we recommend for ocr_image:
{
"version": "1",
"default": "deny",
"tools": {
"ocr_image": {}
}
}ocr_image is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

ocr_image. It is categorised as a Read tool in the Noapi Google Search MCP Server, which means it retrieves data without modifying state.
Register the Noapi Google Search MCP server in PolicyLayer and add a rule for ocr_image: 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 Noapi Google Search. Nothing to install.
ocr_image 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 ocr_image 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 ocr_image. 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.
ocr_image is provided by the Noapi Google Search MCP server (vincentkaufmann/noapi-google-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
