Get list of supported chart types and capabilities
AI agents call get_supported_charts to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

It performs a simple query/lookup with no side effects, no code execution, no data modification, and no destructive operations. The verb 'get' combined with a static configuration query classifies this as a Read operation with low severity and high confidence.
