MCP Transports Working Group

Welcome to the MCP Transports Working Group — a collaborative community focused on improving the usability of transports in the Model Context Protocol (MCP), including scalability, reliability, and semantics.

Mission

The Transports Working Group coordinates community stakeholders to:

• Improve transport usability across MCP implementations
• Define scalability patterns for connection pooling, load distribution, and resource management
• Establish reliability standards for error handling, reconnection, and message delivery guarantees
• Clarify transport semantics for protocol behavior, message ordering, and state management
• Drive interoperability across platforms and implementations

See the CHARTER for detailed scope and processes.
