AI agents call restore-database to permanently remove resources in MCP Firebird — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Restoring a database overwrites the existing database with backup data, irreversibly destroying any changes made since the backup was taken. This is a destructive, non-reversible operation with a critical blast radius — an AI agent misusing this tool could cause complete data loss of all recent transactions and modifications.
From the tool's definition Restores a Firebird database from a backup
Documented attack patterns abuse exactly the kind of access restore-database gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Firebird, and nothing reaches the server without passing your rules. This is the rule we recommend for restore-database:
{
"version": "1",
"default": "deny",
"hide": [
"restore-database"
]
} restore-database disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Restores a Firebird database from a backup. It is categorised as a Destructive tool in the MCP Firebird MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Firebird 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 MCP Firebird. 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 MCP Firebird MCP server (purodelphi/mcpfirebird). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
