@echohello/discord-mcp

Discord MCP server for Claude, Codex, OpenCode and other MCP clients. TypeScript, stdio transport, ~22 focused tools covering the 80% of Discord interactions agents actually need.

npm install -g @echohello/discord-mcp
DISCORD_TOKEN=... discord-mcp

Why

The Discord MCP ecosystem has Java servers, Python servers, and 100-tool kitchen sinks. This one is a small, focused TypeScript implementation built on the official discord.js and @modelcontextprotocol/sdk packages. Tight tool surface, strict TypeScript, and explicit intent behind each tool.

Features

• 22 tools covering guilds, channels, messages, threads, members, roles, webhooks and DMs

• Resolve channels/users/roles by ID or name (case-insensitive)

• Pagination cursors on message history (before / after / around)

• Forum channel support for posts and threads

• Webhook send works without bot context (just a webhook URL)

• Strict TypeScript, zero any, runtime input validation with zod

• Single binary, single env var (DISCORD_TOKEN)

• Optional container image at ghcr.io/echohello-dev/discord-mcp (multi-arch)

Tools

Install

npm install -g @echohello/discord-mcp

Or run without installing:

npx @echohello/discord-mcp

Docker

Multi-arch image (linux/amd64, linux/arm64) at ghcr.io/echohello-dev/discord-mcp. The container speaks stdio, so wire it into any MCP client the same way you would the binary.

docker pull ghcr.io/echohello-dev/discord-mcp
docker run --rm -i -e DISCORD_TOKEN=your-bot-token ghcr.io/echohello-dev/discord-mcp

MCP client configs:

{
  "mcpServers": {
    "discord": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "-e", "DISCORD_TOKEN=your-bot-token", "ghcr.io/echohello-dev/discord-mcp"]
    }
  }
}

Images are tagged on every v*.*.* git tag (see .github/workflows/docker.yml).

Note on visibility: The GHCR package defaults to private on first publish. Flip it to public once via the package settings — the workflow will keep it public on subsequent tags if your token has org admin scope.

Configure your Discord bot

1. Open https://discord.com/developers/applications and create an application.

2. Bot tab → Add Bot → Reset Token → copy it.

3. Bot settings → enable Server Members Intent and Message Content Intent.

4. OAuth2 → URL Generator → scopes: bot → permissions: at minimum

   • View Channels

   • Send Messages

   • Read Message History

   • Add Reactions

   • Manage Messages (for editing/deleting others)

   • Manage Channels (for create/delete channel)

   • Manage Webhooks (for webhook creation)

5. Open the generated URL to invite the bot.

Design notes

• Single transport (stdio). The MCP world is moving toward streamable HTTP, but stdio still has the lowest friction for local agent integration.

• Discord.js v14. Maintained, typed, and the path of least resistance for a Node-native MCP.

• Resolvers accept ID or name. Most users say "send to general"; resolvers translate that into the right channel ID. UUIDs always win when present.

• Pagination cursors are exposed as before / after / around. Matches the underlying Discord.js API so advanced callers can compose anything the client can.

• Forum channels are first-class. Forum posts are just threads with a parent channel of type GUILD_FORUM, so create_thread handles both shapes.

• Webhooks work standalone. send_webhook_message only needs a webhook URL, not the bot context. Useful for CI/CD alerts.

• 22 tools, deliberately. More tools means more cognitive load on the agent. The cut line: anything where the bot can't act without elevated perms (kick/ban/timeout) and anything that's easy to misfire (mass DMs, role cascades) is intentionally excluded.

• Original implementation. Built from scratch on top of the public MCP protocol and public Discord.js API. No code from other Discord MCP implementations.
