# smithery.yaml # # ⚠️ IMPORTANT: Smithery Registry Limitation # # This MCP server uses Server-Sent Events (SSE) transport via StreamableHTTP, # which is NOT currently supported by Smithery's hosting platform. # # Smithery supports: # - STDIO transport (process-based communication) # - Stateless HTTP transport (request/response only) # # But does NOT support: # - SSE/EventSource streaming (which this server uses) # - WebSocket transport # - Persistent connection transports # # This server demonstrates modern MCP best practices with StreamableHTTP + SSE, # making it incompatible with Smithery's current architecture. # # For educational/demo purposes, a STDIO version would be needed for Smithery. # See the MCP SDK documentation for STDIO transport examples. # # References: # - Smithery docs: https://smithery.ai/docs/build/project-config/smithery-yaml # - MCP transports: https://spec.modelcontextprotocol.io/specification/basic/transports/ # # This configuration is provided for reference but will not work on Smithery # due to the SSE transport incompatibility mentioned above. id: yigitkonur/calculator-learning-demo-sse name: Calculator Learning Demo (SSE - Incompatible with Smithery) description: > Educational MCP server demonstrating StreamableHTTP with SSE transport.
