MCP server for rendering isolated interactive canvas artifacts with sandbox isolation, supporting React components and interactive SVG simulators
Critical failures across all dimensions. The single tool 'execute_skill_action' has no visible input schema, no parameter descriptions, and a generic 18-character description that violates the 20-character minimum. The mcp_server.py file contains only a JSON status message with no actual MCP protocol implementation, no tool registration, no schema definitions, no request/response handling. The client.py and example_usage.py files are demo code unrelated to MCP server functionality. This is not a functional MCP server.
Execute skill action for interactive canvas artifact rendering
No input schema visible for execute_skill_action. Tool definition appears inferred only from the status JSON message, not from explicit MCP tool registration.
Tool description is 18 characters ('Execute skill action for interactive canvas artifact rendering'), below the 20-character minimum.
No parameter definitions visible. Tool accepts unknown inputs with no type, constraint, or usage documentation.
mcp_server.py contains only a static JSON print statement. No MCP protocol implementation: no request parsing, no tool invocation logic, no response formatting.

No error handling, no output schema documentation, no recovery guidance. Tool behavior and return type are completely undocumented.
