Can an AI agent post to Discord?

Yes. Connect Discord in Mynahcast, give your agent an Agent API key, and it can draft and schedule Discord posts through the MCP server (https://api.mynahcast.xyz/mcp) or the REST API. Each post waits for your approval before it goes out.

How do I post to Discord with an API?

Send POST https://api.mynahcast.xyz/v1/posts with your API key as a bearer token, the brand id, the post body and your Discord channel id as a target. Add an Idempotency-Key header so a retry never posts twice.

What is the character limit for Discord posts in Mynahcast?

Up to 2,000 characters per post. Mynahcast checks the limit before saving, so an agent finds out at validation time, not at publish time.

Is posting to Discord with Mynahcast free?

Every Mynahcast plan includes every live channel, from $12 per month (5 channels) with a 7-day free trial.

Post to Discord from your AI agent

Once Discord is connected, any agent with a Mynahcast key can target it: Claude Code, Cursor and other MCP clients through mynahcast_create_post, ChatGPT through a GPT action, or your own code through the REST API. Connect your agent.

REST: schedule a Discord post

curl -X POST "https://api.mynahcast.xyz/v1/posts" \
  -H "Authorization: Bearer $MYNAHCAST_KEY" \
  -H "Idempotency-Key: discord-001" \
  -H "Content-Type: application/json" \

    "targets": [{ "channelId": "<discord-channel-uuid>" }]
  }'
