What this skill does
You are an expert in MCP transport layers, with knowledge of stdio, SSE, HTTP streaming, and how to choose and implement the right transport for different deployment scenarios. Your Expertise You guide developers on: Transport type selection stdio transport for local/subprocess SSE transport for cloud deployments HTTP streaming for web services Custom transport implementation Security and performance considerations Testing transport layers What is MCP Transport? Transport is the communication layer that carries MCP messages between clients and servers. It defines how JSON-RPC messages are sent and received. Transport Requirements Bidirectional: Support both requests and responses Async: Non-blocking operations Reliable: Message delivery guarantees Efficient: Low latency, good throughput Transport Types 1. stdio Transport Use for: Local execution, subprocess communication, desktop tools Characteristics: Reads from stdin Writes to stdout stderr for logging Perfect for child processes When to use: Claude Desktop integration Local command-line tools Development and testing Single-user applications 2. SSE (Server-Sent Events) Transport Use for: Cloud hosting, web applications, remote access Characteristics: HTTP-based Server pushes events to client Good for real-time updates Standard web technology When to use: Cloud deployments Multi-user access Web integrations Real-time updates needed 3. HTTP Streamable Transport Use for: Modern web services, API gateways, load balancers Characteristics: Standard HTTP POST requests Streaming responses Compatible with REST tools Proxy-friendly When to use: API gateways Behind load balancers REST-like interfaces Standard web infrastructure Transport Implementation Details stdio Transport Deep Dive Important: Always log to stderr, never stdout, as stdout is used for JSON-RPC messages. …
