Is the Mastodon MCP server free?

Yes. Activepieces is open source and free to start, and the MCP server is included on every plan, from the free cloud tier to any self-hosted deployment.

How do I connect Mastodon to Claude or Cursor?

Connect Mastodon in Activepieces, enable the server under Settings → MCP Server, then paste your server URL into your client config. It authenticates over OAuth on first use.

What can my agent do in Mastodon?

It can call 14 tools, including Post Status, Schedule Status, Get Status, and chain them with steps in other apps inside the same run.

Is it safe to let an agent call Mastodon?

Connections use OAuth2 with limited scopes and are stored under 256-bit encryption, with no API to read them back, so an agent gets scoped access rather than your keys.

Triggers

Mastodon events your agent can watch

These start a run the moment something happens in Mastodon, so work gets picked up on its own.

New Mention
Triggers when someone mentions your account in a post, including replies and direct messages. On mastodon.social and other servers running Mastodon 4.3 or later, direct messages and mentions from accounts you do not follow may be held back by your notification filters (Preferences > Notifications) and will not trigger the flow until you accept them.
New Follower
Triggers when someone starts following your account. If your account requires follow approval, people appear here only after you accept their request.
New Status from Account
Triggers when a specific account publishes a new post. For accounts on other servers, only posts that reach your server are seen, so following the account makes this reliable.
3 fields
New Status with Hashtag
Triggers when a new public post uses a hashtag. Posts from other servers are included once they reach your server.
3 fields

Mastodon MCP, answered.

No. That is the point of it. One Activepieces server exposes Mastodon alongside every other piece you connect, so your client keeps a single connection.
