Can CLI post to social media?

Yes, with Mynahcast. CLI connects by calling the REST API from scripts until the CLI is published. It can then draft and schedule posts to your connected channels (Bluesky, Mastodon, Telegram, Discord, Nostr, Lemmy and more), and each post waits for your approval.

Can CLI publish without my approval?

Not with an Agent key. Agent keys can draft, validate and schedule, but the server refuses approval decisions from agents, so a person approves every post in Mynahcast.

Is it free to connect CLI to Mynahcast?

The MCP server and API are included on every Mynahcast plan, from $12 per month with a 7-day free trial. You need your own access to the agent itself.

Steps

1The myn command line is generated from the same operations as the API, but it isn't published to npm yet.
2Until it is, scripts and cron jobs can call the REST API directly; every command maps one-to-one to an endpoint.

Today: REST from a script

curl -X POST "https://api.mynahcast.xyz/v1/posts" \
  -H "Authorization: Bearer $MYNAHCAST_KEY" \
  -H "Idempotency-Key: rye-thursday-01" \
  -H "Content-Type: application/json" \
  -d '{
    "brandId": "<brand-uuid>",
    "content": { "body": "Rye sourdough is back on Thursday." },
    "targets": [{ "channelId": "<channel-uuid>" }],
    "schedule": { "at": "2026-10-22T08:30:00+02:00" }
  }'

Planned: the CLI

myn posts create \
  --brand-id <brand-uuid> \
  --content '{"body":"Rye sourdough is back on Thursday."}' \
  --targets '[{"channelId":"<channel-uuid>"}]' \
  --dry-run
