Your Idea

Hello everyone!

I've had this crazy idea of proxies between MCP Clients and MCP Servers.

This would allow a bunch of new features, while being totally MCP-compliant.

For instance:

• Logging messages
• Blocking capabilities
• Multiplexing MCP Servers
• Translating content on-the-fly
• And many others...

I drafted a few principles here.

Does it make any sense to you? At least, it does a lot to me. 😁

Feedback would be greatly appreciated!

To keep discussions centralized, you can react here. Thanks!

Scope

• Protocol Specification
• SDK Features
• Documentation
• Developer Experience
• Other

https://github.com/lightconetech/mcp-gateway I implement a mcp proxy to allow Claude desktop talk to remote MCP servers. This is the same architecture with the "simplest form" in your proposal.
