## Why scrape_substack is rated Low

This tool retrieves and queries publicly available Substack publication data (metadata and posts). It has no capability to modify, delete, execute code, or perform financial transactions. The blast radius of misuse is minimal—an agent could retrieve unwanted metadata or harvest public newsletter information, but cannot alter data or trigger harmful operations. Categorized as Read with low severity.

From the tool's own definition: "Tool name 'scrape_substack' and description 'Scrape Substack publication metadata + recent posts' clearly indicate data retrieval with no modification, deletion, or side effects. The example call retrieves publicly available newsletter information."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GoCreative Agent API:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "scrape_substack": {}
  }
}
```
