How to connect it
Buffer's Claude setup guide covers two routes.
Claude on the web or desktop: open the Customize menu, click Connectors, search for Buffer, click Connect and approve access.
Claude Code:
claude mcp add --transport http buffer https://mcp.buffer.com/mcpThen start a session, run /mcp, select the Buffer server, sign in and approve access.
Buffer's integrations page lists guides for ChatGPT and Codex, Cursor, Notion custom agents, Manus, Grok, Antigravity, Perplexity, n8n, Raycast and Zapier. For tools Buffer does not list, an "Other AI tools" guide explains connecting with an API key.
Rate limits
Buffer says MCP requests count against the same limits as API keys, measured over "a 15-minute, 24-hour and 30-day window." Quotas depend on your plan. Successful responses include the remaining quota. When you hit a limit, you get a 429 Too Many Requests error with a Retry-After value in seconds.
Security notes
- "Leave the approval prompts on." That is Buffer's own advice, because
create_postcan publish right away anddelete_postcannot be undone. - Whole-account access. Buffer says the connection covers your whole account. If you manage several brands, everything is in reach.
- Check the URL. Buffer warns you to check the server URL before trusting any one-click install from a third-party list. Only
mcp.buffer.com/mcpis official. - Public posts are public mistakes. A wrong post goes out under your brand. Use
draftorneeds_approvalworkflows where you can. Our MCP approval fatigue guide explains how to keep reviews meaningful. - Untrusted inputs. If the AI drafts posts from web pages or comments, hidden instructions can slip in. See MCP prompt injection.
The MCP security hub covers more.
Alternatives
