Your Question

I’ve been exploring the Model Context Protocol over the past few weeks and ended up building mcp_on_ruby — a lightweight Ruby SDK that implements the MCP spec.

It supports:

• Plug-and-play LLM providers (e.g., OpenAI)

• Tool calling

• Conversation context management

• Streaming support

• Rack/Rails integration

It’s open source and designed for developers building LLM-native apps in Ruby.

I'd love to:

• Contribute this as a community SDK or listed implementation

• Align with the MCP roadmap/spec evolution

• Explore how the Ruby community can participate in the broader MCP ecosystem

Let me know how best to proceed?

The Ruby SDK under the MCP steering group is already being developed at https://github.com/modelcontextprotocol/ruby-sdk. Thank you for the suggestion.
