Can an AI agent post to Hashnode?

Yes. Connect Hashnode in Mynahcast, give your agent an Agent API key, and it can draft and schedule Hashnode 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 Hashnode 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 Hashnode channel id as a target. Add an Idempotency-Key header so a retry never posts twice.

What is the character limit for Hashnode posts in Mynahcast?

Up to 100,000 characters per post. Mynahcast checks the limit before saving, so an agent finds out at validation time, not at publish time.

Is posting to Hashnode with Mynahcast free?

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

REST: schedule a Hashnode post

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

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