ocr_image_file
AI agents call ocr_image_file to retrieve information from EasyOCR MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
OCR is fundamentally a read operation—it extracts and analyzes text content from image files without altering the source data or triggering external operations. While the tool description is empty, the context from the server description and sibling tools (ocr_image_base64, ocr_image_url, unload_ocr_models) all support that this is a data retrieval tool.
From the tool's definition Tool name 'ocr_image_file' and server description indicate this performs Optical Character Recognition on local files, which is a data retrieval/analysis operation with no modifications, deletions, or side effects.

ocr_image_file. It is categorised as a Read tool in the EasyOCR MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EasyOCR MCP Server MCP server in PolicyLayer and add a rule for ocr_image_file: 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 EasyOCR MCP Server. Nothing to install.
ocr_image_file 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_file 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_file. 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_file is provided by the EasyOCR MCP Server MCP server (windoc/easyocr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
