Ruby/Rails client

[tomcsi]

Hello,

Has anyone created a client implementation for the facp-mcp mcp server? I've been trying to find a solution but haven't been successful. Does anyone have a solution?

Seconding this. I have followed the instructions in the readme but I get stuck trying to get a response from the endpoint with a curl request and have not managed to workout how to get Claude Desktop to recognise the server.

Here is working example
for tools

• https://github.com/cs3b/mcp-servers-ruby/blob/master/os/clipboard.rb
  for prompt
• https://github.com/cs3b/mcp-servers-ruby/blob/master/media/summarize_content.rb

and here is small script that helps me with installing it (only testes on macos)

I only have something like this to test mcp server without client - didn't found any client ruby library

# client.rb

require 'json'

server = IO.popen(["/Users/michalczyz/.asdf/shims/ruby", "/Users/michalczyz/Projects/cs3b-mcp-servers-ruby-examples/media/summarize_content.rb"], "r+")

# Send message to server
server.puts %q{{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {}}}
server.flush

# Read response from server
puts server.gets  # => "Server received: Hello, server!"

query = %Q{{"jsonrpc": "2.0", "id": 3, "method": "prompts/list", "params": {}}}
server.puts query

puts server.gets

server.puts query

server.close

You can access your local mcp-server using Copilot Chat extension in agent mode.

1. Expose your local server using something like ngrok

2. You'll have to add your mcp server in setting.json

{ 
...
  "mcp": {
    "servers": {
      "DEFINE_A_NAME": { 
        "url": "NGROK_HOST/mcp/sse"
      },
    },
  },
...
}

If you have enabled authentication add

...
  "mcp": {
    "servers": {
      "DEFINE_A_NAME": { 
        "url": "NGROK_HOST/mcp/sse",
        "headers": {
          "Authorization": "Bearer YOUR_TOKEN"
        },
      },
    },
  },
...

3. Then click on the start button that should appears on top of your mcp declaration
   
   If setup correctly Vscode will discover tools exposed and chat extension will be able to call these tools.

Hope it helps
