Do I need a Mastodon API key?

No. BuzzTake signs in to your Mastodon account the way a person does, so there is no developer app, API key or app review.

Can my AI agent use Mastodon through MCP?

Yes. Add the BuzzTake MCP server to Claude, Cursor or any MCP client. Each Mastodon action is a tool, such as post, reply or send_message.

What does a Mastodon action cost?

A post is 10 credits ($0.10), a reply 8, a like or a follow 3, and a read 4. One credit is one US cent.

Mastodon API for AI agents

Connect your Mastodon account once. Your agent posts, replies, likes and follows, and sends DMs through MCP or REST. No Mastodon API key and no app review.

Automate Mastodon with MCP

Ask in plain words. Your agent makes the call and gets the link back.

A post with media, a content warning in `title` and the `visibility` you choose.

MCP tool call

post

// You: "Post the release note on Mastodon."
// The agent calls the post tool:
{
  "account_id": "acc_mastodon",
  "text": "Version 2.4 is out.",
  "visibility": "public"
}

REST

POST /v1/accounts/acc_mastodon/actions

curl https://api.buzztake.com/v1/accounts/acc_mastodon/actions \
  -H "Authorization: Bearer $BUZZTAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"post","text":"Version 2.4 is out.","visibility":"public","wait":60}'
