Is the Buffer 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 Buffer to Claude or Cursor?

Connect Buffer 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 Buffer?

It can call 3 tools, including Create Post, Create Idea, Custom API Call, and chain them with steps in other apps inside the same run.

Is it safe to let an agent call Buffer?

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.

About the Buffer MCP server

Triggers

Buffer events your agent can watch

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

New Channel
Triggers when a new channel is connected to your Buffer organization. Each check uses one Buffer API request, which counts against your plan limit (Free: 600 a day).
1 field
New Queue Item
Triggers when a new post is queued in Buffer. Each check usually uses one Buffer API request (one more per 100 matching posts, at most 10 per check; any left over are picked up on the next check), which counts against your plan limit (Free: 600 a day).
2 fields
New Sent Post
Triggers when a Buffer post is successfully published. Each check usually uses one Buffer API request (one more per 100 posts sent in the last 24 hours, at most 10 per check), which counts against your plan limit (Free: 600 a day). If more than 1,000 posts are sent in one day, only the 1,000 with the latest scheduled times are checked.

Buffer MCP, answered.

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