WHAT IT DOES

What scrape_polygon does on GoCreative Agent API

AI agents call scrape_polygon 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.

Parameters from the server's own tool schema.

RISK

Why scrape_polygon is rated Low

This tool retrieves public stock market data from Polygon.io. While it is finance-related, it performs only a Read operation (fetching ticker prices and volumes) with no ability to execute trades, move money, or modify any data. The financial context does not elevate the category beyond Read since the tool has no transactional or destructive capability.

From the tool's definition Tool description states: 'Get a Polygon.io stock ticker (price, volume)'. The verb 'Get' and the read-only data returned (price, volume) indicate data retrieval with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs scrape_polygon safely

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

scrape_polygon Allowed

scrape_polygon 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": {
    "scrape_polygon": {}
  }
}

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

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