Fetch the content of a specific markdown file from the documentation
AI agents call get_markdown_file to retrieve information from GameMaker Documentation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves documentation content without any side effects. It does not create, modify, delete, or execute anything - it simply returns existing markdown documentation files. This is a straightforward Read operation with minimal security risk, appropriate for an AI agent to use when seeking information about GameMaker Language functions and documentation.
From the tool's definition Tool description states 'Fetch the content of a specific markdown file from the documentation' - this is a retrieval operation with no modification, deletion, or execution capability. The verb 'fetch' indicates a read-only action.
