crawl_codesys_help · CODESYS MCP Server MCP: Risk & Policy

WHAT IT DOES

What crawl_codesys_help does on CODESYS MCP Server

AI agents invoke crawl_codesys_help to trigger actions in CODESYS MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why crawl_codesys_help needs a policy

This tool performs an active web crawl (external network requests) and indexes the results, making it an Execute-class action. It is not a simple read/query since it has side effects (building/updating a searchable index). It is not Destructive or Financial. Misuse could cause unintended network load or index corruption, hence medium severity.

From the tool's definition 'Crawl https://content.helpme-codesys.com/en/ and index all pages' — actively crawls an external website and writes an index, triggering an external network operation and modifying local indexed data.
