AI agents call get_dify_dsl_version to retrieve information from Dify MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the supported DSL version without querying user data, modifying workflows, executing code, or affecting system state. It is a simple read-only query that returns version information.
