This document outlines the mission, scope, and strategic direction of the MCP Transports Working Group.
The Transports Working Group brings together community participants to:
- Improve transport usability by addressing real-world challenges in MCP implementations
- Define scalability patterns for connection management, load distribution, and resource efficiency
- Establish reliability standards for error handling, reconnection, and delivery guarantees
- Clarify transport semantics for consistent protocol behavior across implementations
- Transport protocol specifications and improvements
- Scalability patterns (connection pooling, multiplexing, load balancing)
- Reliability mechanisms (error handling, reconnection, message delivery)
- Transport semantics (ordering, state management, lifecycle)
- Reference implementations for testing and validation
- Documentation and guidance materials
- Application-layer protocol features (tools, resources, prompts)
- Domain-specific extensions (financial services, healthcare, etc.)
- Competitively sensitive information
- Non-technical business matters
The group adheres to the MCP Antitrust Policy; all participants must follow antitrust compliance guidelines.
Transport proposals developed within this working group address specific transport challenges while enabling:
- Rapid iteration and experimentation
- Community feedback gathering
- Production validation before standardization
Broadly applicable proposals may advance to the core MCP specification through:
- SEP (Spec Enhancement Proposal) documenting the proposal and implementation evidence
- Core Maintainer Sponsorship from MCP leadership
- Community Consensus via the SEP review process
The Working Group identifies promising proposals and actively pursues promotion by:
- Providing real-world validation from production environments
- Building coalition support among contributors
- Coordinating with core maintainers for SEP sponsorship
Charter changes require:
- Proposal through GitHub
- Discussion and community input
- Maintainer consensus approval
- Clear documentation of rationale
Questions about this charter can be directed to:
- The
#transports-wgDiscord channel - GitHub Issues in this repository
- Maintainers listed in GOVERNANCE.md
