Perform OCR on images to extract text with confidence scores. Supports screenshots, scanned documents, photos of text. Returns structured text with confidence metrics. Essential for agents processing visual content.

AI agents invoke parse_image_text to trigger processes or run actions in Document Parser. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
parse_image_text can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access parse_image_text gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Perform OCR on images to extract text with confidence scores. Supports screenshots, scanned documents, photos of text. Returns structured text with confidence metrics. Essential for agents processing visual content.. It is categorised as a Execute tool in the Document Parser MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Document Parser MCP server in PolicyLayer and add a rule for parse_image_text: 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 Document Parser. Nothing to install.
parse_image_text is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the parse_image_text 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 parse_image_text. 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.
parse_image_text is provided by the Document Parser MCP server (@agenson-horrowitz/document-parser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
