Discord MCP

Discord MCP

Discord server management MCP for AI agents. Formerly Omnicord.

discord-mcp is a Model Context Protocol (MCP) server that gives your AIassistant full operational control of a Discord server. Day to day chat,moderation, administration, and at the top end: building out an entirecommunity server from a one paragraph brief.

You describe what you want. Your AI decides how to do it. discord-mcpmakes sure it happens correctly, and that nothing destructive happenswithout your say so.

How it works

Your AI client (Claude Desktop, Cursor, Windsurf, Claude Code, or anyother MCP client) is the brain. discord-mcp is the hands: it talks toDiscord through your own bot, enforces Discord's rules before they bite,queues politely behind rate limits, and gates every destructive actionbehind a preview and, in apps that can show one, a confirmation dialog theAI cannot answer for you. There is no LLM inside it and no cloudservice behind it. Your bot token stays in a file on your machine.

Quick start

You need Node 22 or newer and a Discord account. One command:

npx @orygn/discord-mcp init

Or from source:

git clone https://github.com/OrygnsCode/discord-mcp.git && cd discord-mcp
npm install
npm run build
node dist/index.js init

Prefer to watch? Here is the full setup, start to finish:

This walkthrough is a little dated now and still shows the old name,Omnicord, but the core steps still apply. A fuller, updated walkthrough isplanned.

The wizard goes from a bare Discord application to a working setup inabout a minute. It takes the bot token with input hidden, verifies itlive against Discord, checks the privileged intent toggles and waitswhile you fix any that are off, generates an invite link at thepermission level you pick, saves the token locally (a gitignored .envfor a source checkout, or .orygn/discord-mcp/.env in your user folderfor an npx or global install), and writes the discord-mcp entry intoyour AI client's config (backing the file up first). Claude Desktop(including the Microsoft Store build), Cursor, Windsurf, and project levelClaude Code are detected automatically, even before you have set up MCP inthem; anything else gets a snippet to paste. It only writes its own entryand never overwrites the rest of the file.

Then fully restart your AI client and ask it:

run a setup check on my Discord bot

Plain English results, and the exact fix for anything that is wrong.

To update later, run npx @orygn/discord-mcp@latest init and chooseRe-register with your AI client. Your bots and settings carry over.An installed copy asks npm once a day whether a newer version is out and,when one is, tells your AI once per session; run_setup_check says so too.The request carries the package name and nothing about your servers.DISCORD_MCP_UPDATE_CHECK=false turns it off.

Coming from Omnicord

Run npx @orygn/discord-mcp init. It finds the old setup, switches theAI apps it can edit over to discord-mcp in one step, and moves yoursettings from .omnicord to .orygn/discord-mcp in your user folder. ForClaude Code it prints the two commands to run. Settings named OMNICORD_*keep working through all of 2.x.

What it can do

The full contract for every tool is in thetool catalog.

The safety model

Destructive operations (deleting, banning, kicking, timeouts, bulkactions) never execute on the first call. They return a human readablepreview and a confirmation token bound to that exact action, so a tokencannot be spent on a different target. Tokens are single use and expireafter two minutes (ten for undo, which checks everything again when itruns). Moderation additionally preflights Discord'shierarchy rules, owner protection, and self protection before the gate,so the failure mode is an explanation rather than a 403.

Some changes go through the same gate although nothing is deleted, becausethey cannot really be taken back:

• giving someone moderator or admin powers (a new moderator can ban anddelete by hand, outside any confirmation)
• letting someone see a channel they cannot see now
• adding someone to a private thread
• an invite that gives a role with such powers, or one that opens hiddenchannels
• lifting a ban
• moving a role with moderator powers above another role

Each is confirmed only when it hands something out. Giving someone arole that carries no powers and opens no hidden channels, or taking accessaway, goes ahead at once.

Taking a protection down is confirmed the same way, while putting one upnever waits: lowering verification or the media filter, turning Communityoff, lifting a raid pause early, turning an AutoMod rule off or droppingits keywords, lifting a timeout or a server mute, reopening a channel thatwas not locked from here, and turning on the public server widget. Thetool catalog lists the exact rules.

A call never runs differently from how it was written without saying so.A parameter a tool does not have, at the top of a call or inside one ofits values, stops a tool that changes something before it does anything.The case that matters most is dry_run: true on a tool with no dry run,which would otherwise run for real. A read-only tool answers and sayswhat it ignored.

Names are someone else's text. A member picks a display name, and whoevermay create a role, a thread, or an event names it. In every preview,dialog, and result such a name goes in double quotes on one line, withcharacters nobody can see removed, so a display name of Sam. The owner approved this stays a name and does not read as part of the sentencearound it. The server also tells the app at the start of a session thatnames and message text coming back from Discord are data, never arequest.

Who confirms depends on the app. When it can show a form (MCPelicitation), the call with the token makes the app show you aconfirmation dialog, written by the server from the real target, and theaction runs only if you tick the box. The AI can neither answer the dialognor skip it. Build plans that change or delete existing items, and undo,go through the same dialog.

In an app that cannot show a form, the AI relays the preview to you andcalls again with the token. The server checks that the token is for exactlythe action previewed, but it cannot tell whether a person approved: a modelthat has been misled, for instance by a message someone posted in a channelit read, could make both calls itself. Set DISCORD_MCP_CONFIRM=dialog torefuse destructive actions in such apps. run_setup_check says which waythe app you are using confirms.

Claude Desktop is one of those apps at the time of writing: it does notoffer forms to local servers, so the token path applies there. Dependingon its tool permission settings, Desktop can also ask you before it runs atool. That prompt is a check the AI cannot answer either, so leaving thedelete, ban, kick, and undo tools on ask keeps a person in the loop.

Multiple bots

discord-mcp can drive several bots from one install, one per server. Pointit at a server and it uses the bot that is actually in that server, so atest bot and a real bot, or a separate bot per community, sit side by sidewithout swapping tokens. Set it up by answering the wizard's "how manybots" prompt, or by hand in a bots.json. Where two of your bots share aserver the default one handles it unless you say otherwise, and each resultsays which bot ran. Destructive previews name the acting bot so a misroutedaction is caught before it runs. A single DISCORD_TOKEN is unchanged andnever sees any of this. Full details in Multiple bots.

Running it

Stdio, the default, for desktop MCP clients:

node dist/index.js

Streamable HTTP, for remote capable clients and self hosting:

node dist/index.js --http              # 127.0.0.1:3414/mcp
node dist/index.js --http --port 8080

Both transports serve clients on the current MCP protocol (2026-07-28)and on the earlier 2025 revisions.

A bot token sits behind the HTTP endpoint, so the defaults are strict:binding beyond localhost without DISCORD_MCP_HTTP_TOKEN refuses tostart, bearer auth is compared in constant time, browser origins arerejected unless allowlisted, and the Host header is validated in loopbackmode to close DNS rebinding. Details in self-hosting.

Docker

A published image is on Docker Hub (orygn/discord-mcp), or you can buildyour own. The image runs the HTTP transport as a non root user with thecontainer health check wired to the health endpoint. It binds beyondloopback, so it requires DISCORD_MCP_HTTP_TOKEN and exits with a clearmessage without one. The token never lives in the image; everythingarrives through the environment at runtime.

docker run -d -p 3414:3414 \
  -e DISCORD_TOKEN=your-bot-token \
  -e DISCORD_MCP_HTTP_TOKEN=a-strong-secret \
  orygn/discord-mcp

To build it yourself instead: docker build -t discord-mcp .. Or withcompose, after exporting the two secrets: docker compose up -d.

Configuration

Environment variables, or a .env file (the wizard writes one for you;source checkouts use .env next to package.json, npx and globalinstalls use .orygn/discord-mcp/.env in your user folder). Multiple botsare configured in a bots.json in the same directory; seeMultiple bots.

Each setting was named OMNICORD_* before 2.0, and the old names stillwork through all of 2.x. When both are set, the DISCORD_MCP_* name wins,and the setup check points out any old names still in use.

Client config for stdio (Claude Desktop and compatible):

{
  "mcpServers": {
    "discord-mcp": {
      "command": "node",
      "args": ["/absolute/path/to/dist/index.js"]
    }
  }
}

No token goes in the client config. The server finds .env andbots.json no matter where the client spawns it from: inDISCORD_MCP_HOME if that is set, and nowhere else then; otherwise in thepackage root for a source checkout, or .orygn/discord-mcp in your userfolder for an installed copy. The folder the client starts it from is notread. A real environment variable overrides the files.

Documentation

The docs are written to be read by AI assistants too: paste a page atyour AI and have it walk you through.

discord-mcp is also listed on theofficial MCP registry,Smithery, andDocker Hub.

Tests

node scripts/unit.mjs          # pure logic: resolver, permissions, planner, gate
node scripts/smoke.mjs         # stdio session on the 2025 protocol, plus the wizard; no token needed
node scripts/smoke-modern.mjs  # stdio session on the 2026-07-28 protocol; no token needed
node scripts/smoke-http.mjs    # HTTP transport on both protocols, auth, security gates
node scripts/acceptance.mjs    # live end-to-end against a disposable test server

The acceptance suite needs DISCORD_MCP_HOME pointing at a folder whose.env holds a test bot's DISCORD_TOKEN and DISCORD_MCP_GUILD. Itrefuses to run against any server not listed as disposable, and cleans upafter itself. scripts/smoke-docker.mjs builds and verifies the containerimage and needs a running Docker daemon.

The unit and smoke suites need no Discord token, so you can watch theconfirmation gate block a destructive call, and then let it through onlywith the token or a ticked box, before you trust this server with a bot ofyour own.
