WHAT IT DOES

What list_posts does on Cloudflare

AI agents call list_posts to retrieve information from Cloudflare without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_posts is rated Low

This tool retrieves and queries publicly available blog post data from Cloudflare with no capability to modify, delete, or execute operations. It is purely informational in nature. The severity is low because misuse would only result in excessive API calls or data retrieval, with no blast radius to systems or data integrity.

From the tool's definition Tool description explicitly states 'List Cloudflare Blog posts in reverse chronological order' with optional tag filtering and pagination support. The verb 'List' and the operation of querying blog posts are indicative of data retrieval without side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_posts safely

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

list_posts Allowed

list_posts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_posts": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Cloudflare, apply this rule, and every list_posts call is checked against it from then on.
