## Facts

- Tool: `optimize_dns_performance`
- Server: 20i MCP Server (`cbrown35/20i-mcp`) — https://policylayer.com/tools/cbrown35-20i-mcp.md
- Homepage: https://github.com/Cbrown35/20i-MCP
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "optimize_dns_performance",
    "arguments": {}
  }
}
```

## 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.

From the tool's own definition: "Optimize DNS performance with caching and geo-DNS"

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches 20i MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "optimize_dns_performance": {
      "limits": [
        {
          "counter": "optimize_dns_performance_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
