What is Studio

Studio is a command-line interface (CLI) tool designed to facilitate the creation and management of multi-command processor (MCP) servers. It allows users to define, configure, and utilize custom command tools with a focus on simplicity and efficiency.

Use cases

Studio can be used for a variety of purposes, including setting up echo servers, running Git log commands, or generating Rails scaffolds. It provides a versatile environment for developers to create specialized command tools tailored to their tasks.

How to use

To use Studio, install it via the command ‘gem install studio’. Define new tools with the command ‘claude mcp add studio ’. You can also set up configurations in your MCP server and interact with it using JSON-RPC protocols for various operations.

Key features

Key features of Studio include the ability to create blueprints for tools, interactive command server functionality, customizable command/event handling, and simple integrations with text prompts to gather user input.

Where to use

Studio can be used in development environments for CLI tools, within scripts for automated tasks, or as part of a broader application development pipeline where custom command execution is necessary. It fits well in scenarios where lightweight, tailored command servers are needed.

Studio

Make any CLI into a single tool MCP server.

Install

$ gem install studio

Claude Code

#                <serv-name> studio <cmd> <arguments or blueprints>
$ claude mcp add echo-server studio echo "{{text#What do you want to say?}}"

$ claude mcp add git-log studio git log --one-line -n 20 "{{branch}}"

Cursor

Make sure studio is installed, then

Add to your .cursor/mcp.json manually:

{
  "mcpServers": {
    "echo": {
      "command": "studio",
      "args": [
        "echo",
        "{{text#What do you want to say?}}"
      ]
    },
    "rails": {
      "command": "studio",
      "args": [
        "rails",
        "generate",
        "{{generator # A valid rails generator like scaffold, model}}"
      ]
    }
  }
}

VSCode

Pay attention, one says stdio, the other says studio! (uh oh, what have I done?)

Do you speak MCP?

$ studio echo

Now you’re speaking to the mcp server, so say something smart.

ping

{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "ping"
}

or not… just play ping pong if you wish.

initialize

{
  "jsonrpc": "2.0",
  "id": "2",
  "method": "initialize",
  "params": {
    "protocolVersion": "2024-11-05",
    "capabilities": {},
    "clientInfo": {
      "name": "test-client",
      "version": "1.0.0"
    }
  }
}

that’s better…

list tools

{
  "jsonrpc": "2.0",
  "id": "3",
  "method": "tools/list"
}

Oh look, a hammer…

use tool

{
  "jsonrpc": "2.0",
  "id": "4",
  "method": "tools/call",
  "params": {
    "name": "echo",
    "arguments": {
      "args": [
        "hello",
        "world"
      ]
    }
  }
}
