What restore_database does on Mcpg
AI agents call restore_database to permanently remove resources in Mcpg, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why restore_database is rated Critical
A database restore operation overwrites the current state of the database with backup data, which is an irreversible destructive action that eliminates any data created or modified since the backup was taken. This has a critical blast radius as it can affect the entire database. Confidence is slightly reduced because the description is empty, but the tool name strongly implies this behavior.
From the tool's definition Tool name 'restore_database' — restoring a database typically overwrites existing data irreversibly, replacing current database contents with a prior snapshot or backup.
Attacks that exploit this kind of access
The rule that runs restore_database safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcpg, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For restore_database, this is the rule to start with:
restore_database is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcpg, apply this rule, and every restore_database call is checked against it from then on.
Questions about restore_database
restore_database is a destructive tool on the Mcpg MCP server. It is categorised as a Destructive tool in the Mcpg MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcpg MCP server in PolicyLayer and add a rule for restore_database: 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 Mcpg. Nothing to install.
restore_database is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the restore_database 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_database. 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_database is provided by the Mcpg MCP server (pypi:mcpg). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
