Fetches a web article
AI agents call fetch_web_article to retrieve information from FlexFS MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves remote web content and returns it to the user. Fetching web articles is a read-only operation with no side effects on the source, the file system, or any data store. The blast radius is minimal—misuse would result in fetching unintended articles, not data corruption, financial loss, or system compromise. Classification as Read with low severity is appropriate.
From the tool's definition Tool name 'fetch_web_article' and description 'Fetches a web article' indicate retrieval of publicly accessible web content with no data modification, creation, or deletion.
