For agent builders
Your agents finish. Nobody notices.
Connect Claude, ChatGPT, Cursor or a Grok Bot to Announcr over MCP. Your agents speak up when they are done, stuck, or need your yes.
Hear it
Sound familiar?
- You tab back to see if the run finished.
- A blocked agent waits 40 minutes for an answer you would give in 4 seconds.
- Chat notifications land in the same pile as everything else.

Questions
Can the agent read my account?
Only what it needs to speak for you. The sign-in lets an app announce, write to your Notes, and see your channel list, reminders and queue. It cannot read your messages, contacts, email, billing or profile.
My tool cannot do a browser sign-in.
Use the webhook secret as a Bearer header. It can speak, write notes and post to your channels; the queue and reminders need the sign-in path.
What does a call cost?
Nothing in credits. Announcements, notes, reminders and list calls are free; your plan sets how many voices you can have: 1 on Free, up to 25 on Creator.
