WHAT IT DOES

What optimize_dns_performance does on 20i MCP Server

AI agents use optimize_dns_performance to create or update resources in 20i MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 20i MCP Server environment.

RISK

Why optimize_dns_performance is rated Medium

Optimizing DNS performance involves modifying DNS configuration settings (enabling/configuring caching and geo-DNS routing), which constitutes a reversible Write operation. While DNS changes can affect site availability and routing, they are generally reversible. Confidence is moderate because the description is vague and doesn't specify exactly what changes are made or whether any destructive actions could occur.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs optimize_dns_performance safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 20i MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For optimize_dns_performance, this is the rule to start with:

optimize_dns_performance Rate-limited

optimize_dns_performance stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about optimize_dns_performance

What does the optimize_dns_performance tool do? +

Optimize DNS performance with caching and geo-DNS. It is categorised as a Write tool in the 20i MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on optimize_dns_performance? +

Register the 20i MCP Server MCP server in PolicyLayer and add a rule for optimize_dns_performance: 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 20i MCP Server. Nothing to install.

What risk level is optimize_dns_performance? +

optimize_dns_performance is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit optimize_dns_performance? +

Yes. Add a rate_limit block to the optimize_dns_performance 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 optimize_dns_performance completely? +

Set action: deny in the PolicyLayer policy for optimize_dns_performance. 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 optimize_dns_performance? +

optimize_dns_performance is provided by the 20i MCP Server MCP server (cbrown35/20i-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
