Download a file from OneDrive to local path
AI agents call get_file to retrieve information from Microsoft MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file content from OneDrive and saves it locally. It has no side effects on the source data—no creation, modification, deletion, or execution occurs. While the sibling server includes destructive tools (delete_email, delete_contact, delete_event), get_file itself is a read-only retrieval operation.
From the tool's definition Tool name is 'get_file' with description 'Download a file from OneDrive to local path'. Download operations retrieve data without modifying or deleting the source.

Register the Microsoft MCP server in PolicyLayer and add a rule for get_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 Microsoft MCP. Nothing to install.
get_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 get_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 get_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.
get_file is provided by the Microsoft MCP server (purva-kashyap/microsoft-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
