DisCatSharp

A Discord app library written in C# for .NET

---

Why DisCatSharp?

If you:

• want a library where you get kind and efficient help
• would like to have and use the most recent features of the Discord API
• are ready to build great things

Then this is the right place for you!

History

We squashed DisCatSharp's Git history because of its clone size and accumulated clutter. The original history remains available through the releases, tags, and the archived pre-squash repository.

Install

Install the latest stable release from NuGet:

dotnet add package DisCatSharp

To use the latest nightly release instead:

dotnet add package DisCatSharp --prerelease

Packages are also available from GitHub Packages.

Quick start

Create a Discord bot account, store its token in the DISCORD_TOKEN environment variable, and connect the client:

using DisCatSharp;
using DisCatSharp.Enums;

string token = Environment.GetEnvironmentVariable("DISCORD_TOKEN")
    ?? throw new InvalidOperationException("Set the DISCORD_TOKEN environment variable.");

var discord = new DiscordClient(new DiscordConfiguration
{
    Token = token,
    TokenType = TokenType.Bot,
    Intents = DiscordIntents.AllUnprivileged
});

await discord.ConnectAsync();
await Task.Delay(Timeout.InfiniteTimeSpan);

Continue with the complete first bot guide.

Documentation

The documentation is available at docs.dcs.aitsys.dev. A backup is available at backup-docs.dcs.aitsys.dev.

AI coding assistants

Install the consumer skill globally for Codex:

gh skill install Aiko-IT-Systems/DisCatSharp use-discatsharp --agent codex --scope user --pin main

Then add the public, stateless documentation MCP as a Streamable HTTP server named discatsharp:

[mcp_servers.discatsharp]
url = "https://docs.dcs.aitsys.dev/mcp"

The MCP provides live documentation search, symbol lookup, full-page retrieval, and indexed source access. See the Agent Skills and MCP setup guide for GitHub Copilot, Claude Code, Gemini CLI, other Agent Skills clients, version pinning, and maintainer guidance.
