How to post to Discord from Claude

Add PostDelegate to Claude. In Claude open Settings, then Connectors, then Add custom connector. Name it PostDelegate and paste the server URL below. Choose Add, then Connect, sign in to PostDelegate and click Authorize.
Server URL
```
https://app.postdelegate.com/mcp-oauth-dynamic
```
Custom connectors depend on your Claude plan and, on team plans, on what your organisation allows.
Connect Discord in PostDelegate. On the calendar page choose Add Channel, then Discord. Choose the server and approve. You need the Manage Server permission there. The bot is allowed to send messages, create threads and send messages in threads.
Ask Claude for a draft. Describe the post in plain words. Claude checks your Discord channel's rules, creates the post and sends back a preview link.

Teach Claude the posting rules

Add the PostDelegate skill to Claude so it knows the posting rules before it writes: download the skill zip and upload it under Customize, then Skills, with code execution turned on. Agent files has the steps.

What to ask Claude

Mention any Discord setting in plain words and Claude fills it in. Start with something harmless, like asking which channels you have.

Draft an announcement for our Discord #announcements channel about the new feature, under 1,980 characters, using a heading and a bullet list.
Which Discord channels can PostDelegate post to? Schedule “Office hours start in 10 minutes” in the community one at 14:50.

What Claude can do on your Discord channel

Check the rules first. Before writing, it reads your Discord channel's length limit (1,980 characters) and required settings.
Draft, schedule or post. It creates a draft, a scheduled post or an immediate post, and runs the same checks as the app.
Use your media. It attaches files from your media library or adds one from a public link.
Review and fix. It lists what is scheduled, changes the Discord settings of a post that has not gone out, and deletes posts you no longer want.

Discord servers run on announcements: patch notes, event reminders, stream alerts and the weekly community call. PostDelegate sends each scheduled post as a message from its bot to the channel you choose, so the announcement goes out on time without anyone online to press send.

Discord settings Claude can fill in

Setting	Notes
Channel	Required. Choose a text or announcement channel in the server. Forum channels show in the list but cannot take messages.

Attachments	Images or videos, uploaded as files with the message. Discord takes up to 10 files per message.

Before you start

Private channels need the bot added in Discord, with permission to view the channel and send messages.
Messages are sent from the PostDelegate bot, not your own Discord account.

The Discord channel guide has every field, and MCP tools lists exactly what an assistant can and cannot do.

Questions

Will Claude publish to Discord without asking me?

Not unless you ask it to. Ask for a draft and the post waits on your calendar until you schedule it, and your workspace's approvals apply as usual. Tools that change data are marked as such, so Claude can ask you before it schedules or deletes anything.

Do I need an API key to connect Claude?

No. Claude signs in with your PostDelegate account through your browser. An API key is only for clients that cannot sign in, as described in MCP clients.

Does it cost extra to use Claude with PostDelegate?

No. The MCP server is on every plan, and Claude runs on your own Claude account, so PostDelegate never charges for AI. Every plan starts with a 7-day free trial with no card.

Can Claude attach images or video to a Discord post?

It can use files already in your media library, or add one from a public link. It cannot fetch files from your computer, so upload those in the app first, or through the upload widget where Claude shows it. See MCP tools.

Does the message come from my own Discord account?

No. Posts are sent by the PostDelegate bot that you add to your server. PostDelegate never posts as your personal Discord account.

Can I post to a private Discord channel?

Yes. The bot cannot see private channels by default. In Discord, open the channel's settings, then Permissions, and add the PostDelegate bot with View Channel and Send Messages. Then pick the channel in the post settings.
