use official gem

[funwarioisii]

https://github.com/modelcontextprotocol/ruby-sdk is released.

For mcp-rb, I want to leverage the official SDK for the detailed MCP implementation while adding DSL and remote support features to enhance convenience while maintaining safety.

That sounds like a great plan! I didn't even know that existed. Great idea to build on it instead of having to keep up with the moving target.

I really miss the simplicity of his gem, but the schema updates make it so that this falls over (#33)

I hope you haven't given up, because your interface is far superior to that of the "official" Ruby MCP gem.

Theirs:

require 'mcp'
require 'mcp/server/transports/stdio_transport'

# Define the tool using MCP::Tool.define method
square_tool = MCP::Tool.define(
  name: "square",
  description: "square an int",
  input_schema: {
    properties: {
      num: { 
        type: "number",
        description: "the integer to square"
      }
    },
    required: ["num"]
  }
) do |args, server_context|
  result = args[:num] ** 2
  
  MCP::Tool::Response.new([{
    type: "text",
    text: result.to_s
  }])
end

# Create the server
server = MCP::Server.new(
  name: "square",
  version: "0.0.1",
  tools: [square_tool]
)

# Set up stdio transport
transport = MCP::Server::Transports::StdioTransport.new(server)
transport.open

Yours:

require 'mcp'

name 'square'
version '0.0.1'

tool 'square' do
  description 'square an int'
  argument :num, Integer, required: true,
           description: 'the integer to square'

  call { |num:| num**2 }
end

Its clear which one was made with ❤️
