Hosting

Vendor-hosted remote MCP service

Transport

Streamable HTTP

Endpoint

https://mcp.buffer.com/mcp

Authentication

OAuth is recommended; documented API-token authentication is also available.

Requirements

• Buffer account with the channels and permissions to be managed.
• MCP client supporting remote Streamable HTTP and OAuth.

Setup steps

1. Add https://mcp.buffer.com/mcp as a remote Streamable HTTP server.
2. Complete Buffer OAuth in the MCP client; use a token only through the client’s secure secret mechanism if OAuth is unavailable.
3. Inspect tools/list and confirm the target channels before scheduling or editing posts.
