Automation

n8n integration for Buffer

n8n is an open-source workflow automation tool that connects Buffer to hundreds of services. Host it yourself for full control over your data, or use n8n Cloud. Either way, you get a powerful visual editor for building social media automation workflows.

Getting started

You'll need an n8n account (cloud or self-hosted) and your Buffer API key. Go to publish.buffer.com/settings/api and copy an existing API key or click + Generate API Key to create a new one.

  1. In n8n, open a workflow and add an MCP Client node
  2. Fill in the node: Server Transport — HTTP Streamable, MCP Endpoint URL — https://mcp.buffer.com/mcp, Authentication — Bearer Auth
  3. Click Credential for Bearer Auth, select Create new credential, paste your API key, and click Save
  4. Select the Buffer MCP tool you want the workflow to use and configure it as needed

n8n supports multi-step workflows — you can add logic, filters, and AI steps between your trigger and Buffer before content is posted.
