process_local_file
AI agents call process_local_file to retrieve information from MCP Mistral OCR Optimized without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and processes local files to extract text/table content via OCR—a read operation. The server context emphasizes extraction and formatting, not creation, modification, or deletion of source files. While the description is empty, the name and sibling tools (batch job operations, result downloads) confirm read-focused functionality.
From the tool's definition Tool name 'process_local_file' and server description indicate OCR processing: 'extraction of text and tables from local files' with output in 'structured markdown and HTML formats'. This is data retrieval with no destructive or modifying operations mentioned.

process_local_file. It is categorised as a Read tool in the MCP Mistral OCR Optimized MCP Server, which means it retrieves data without modifying state.
Register the MCP Mistral OCR Optimized MCP server in PolicyLayer and add a rule for process_local_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 MCP Mistral OCR Optimized. Nothing to install.
process_local_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 process_local_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 process_local_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.
process_local_file is provided by the MCP Mistral OCR Optimized MCP server (snussik/mcp_mistral_ocr_opt). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
