restart_database · PlugLayer MCP Server MCP: Risk & Policy

WHAT IT DOES

What restart_database does on PlugLayer MCP Server

AI agents invoke restart_database to trigger actions in PlugLayer MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why restart_database needs a policy

Restarting a database is an Execute action because it triggers an external operation (database service restart/redeploy) whose real-world effects depend on the database being targeted. While reversible (unlike Destructive), it is not a simple read query (Read) or data modification (Write), but rather an operational procedure that executes infrastructure changes.

From the tool's definition Tool 'restart_database' performs an operational action that queues a redeploy/restart flow for a provisioned database. The word 'restart' and 'redeploy' indicate active manipulation of infrastructure state.

Verdict

restart_database Rate-limited

restart_database stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

What does the restart_database tool do? +

Restart a provisioned database by queueing its redeploy/restart flow. It is categorised as a Execute tool in the PlugLayer MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on restart_database? +

Register the PlugLayer MCP Server MCP server in PolicyLayer and add a rule for restart_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 PlugLayer MCP Server. Nothing to install.

What risk level is restart_database? +

restart_database is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit restart_database? +

Yes. Add a rate_limit block to the restart_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.

How do I block restart_database completely? +

Set action: deny in the PolicyLayer policy for restart_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.

What MCP server provides restart_database? +
