Repl is the recommended starting point for Repl Toolkit.

Repl Toolkit lets .NET applications define one command graph and expose it as CLI commands, an interactive REPL, remote interactive REPL sessions hosted by your app, structured output for automation, and MCP tools for AI agents.

This meta-package brings the default dependencies most apps need:

  • Repl.Core
  • Repl.Defaults
  • Repl.Protocol

Install

dotnet add package Repl

Minimal app

using Repl;

var app = ReplApp.Create().UseDefaultInteractive();
app.Map("hello", static () => "world");

return app.Run(args);

Run it as a CLI command:

myapp hello --json

Run it with no arguments to enter the interactive REPL:

myapp

When to use Repl Toolkit

Use Repl for small and large command surfaces alike when your application benefits from:

  • CLI commands for humans, scripts, or CI;
  • interactive exploration with a REPL;
  • structured output such as JSON, XML, YAML, or Markdown;
  • remote interactive REPL sessions on remote connections such as Telnet, WebSocket, or other stream-based integrations;
  • MCP tools, resources, prompts, or MCP Apps for AI agents;
  • tests that exercise the same command surface end-to-end.

Repl Toolkit keeps tiny command surfaces concise while making the same command graph ready for humans, scripts, tests, remote sessions, and agents as the application grows.

Add MCP later

When the same commands should be available to AI agents, add Repl.Mcp:

dotnet add package Repl.Mcp

using Repl.Mcp;

app.UseMcpServer();

Then run:

myapp mcp serve
