Preview a local backup file for restore planning. This never writes to Microsoft To Do.
AI agents call restore_preview to retrieve information from Microsoft Todo Safe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool explicitly reads and previews a local backup file without making any changes or writes. It is purely a read/query operation with no side effects.
From the tool's definition 'Preview a local backup file for restore planning. This never writes to Microsoft To Do.'

Register the Microsoft Todo Safe MCP server in PolicyLayer and add a rule for restore_preview: 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 Todo Safe. Nothing to install.
restore_preview 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 restore_preview 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 restore_preview. 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.
restore_preview is provided by the Microsoft Todo Safe MCP server (saenai/microsoft-todo-safe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
