3 integrations · MCP · GraphQL · CLI

Buffer exposes a GraphQL API at https://api.buffer.com, an MCP server at https://mcp.buffer.com/mcp, and a `buffer` CLI (`@bufferapp/cli`); all documented developer surfaces require authentication, primarily via a personal Buffer API key, with the GraphQL API also supporting OAuth 2.0 app tokens.

Credentials

Buffer personal API keybearer$ buffer init

Acquired by the CLI — running buffer init opens the auth flow and stores the credential.

OAuth 2.0oauth2

OAuth 2.0 — self-onboarding

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
