list_articles
AI agents call list_articles to retrieve information from Cartesi Knowledge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or lists articles from curated Cartesi developer resources without modifying, deleting, or executing code. This is a typical Read operation. Confidence is moderate-high despite missing tool description because the server's read-only mandate and sibling tool patterns provide strong contextual evidence. Severity is low as listing articles poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'list_articles' and server context indicate a read-only operation querying curated documentation.
