How much does the Buffer API actually cost?
Buffer publishes an API, but per-tier gating wasn't extracted automatically.
- Most likely scenario: API access is either included in all paid plans, or it's gated to higher tiers and we need to verify on the live docs page.
- Until verified, treat the question "which plan unlocks the API" as open. Don't budget on the assumption it's free with the cheapest paid plan.
API at a glance
Which AI clients can read Buffer data?
Not every AI assistant supports MCP natively. Here's the per-client picture for Buffer specifically.
| Client | Support | Notes |
|---|---|---|
| Claude (Desktop/Web) | Native MCP | — |
| Claude Code | Native MCP | — |
| ChatGPT | Native MCP | — |
| Cursor | Native MCP | — |
| n8n | Native MCP | — |
Buffer also has an MCP server
If you're wiring Buffer into Claude / Cursor / Codex, the MCP server is usually less code than the REST API.

Three personas, three different shapes of build. Pick the row that matches how you actually ship.
Glue Buffer into your daily workflow
- Pull a digest of fresh activity into your morning Slack
- Trigger a one-off backfill when something looks off
- Pipe data into your own SQLite for ad-hoc queries
Sell Buffer reporting at scale
- White-label Buffer data into client-branded dashboards
- Run scheduled multi-account reports without logging into the Buffer UI
- Cross-reference with the rest of the client's stack (CRM, analytics, ad spend)
Production pipelines for Buffer
- Real-time sync into your warehouse on a cron
- Custom alerts the dashboard's built-in alerting can't express
- Backfill + idempotency handling for Buffer data older than the dashboard exposes
Quickstart template
# Starter template — endpoint paths and SDK package names come from # the Buffer API docs: https://buffer.com/mcp curl -X GET "https://buffer.com/<your-endpoint>" \ -H "Authorization: Bearer $TOKEN" \ -H "Accept: application/json" | jq .
Template only. Endpoint paths, exact base URL, and auth header format come from buffer.com/mcp.
Limits and gotchas
- No OpenAPI spec — you write typed clients by hand or use a third-party generator on the docs HTML.
- Official SDKs: node. Use them to skip auth boilerplate and get type safety.
- Rate limits: always read the docs page before scaling — the published limit is usually lower than the practical one and overages can be expensive.
Agent-readiness verdict
A modern GraphQL API that genuinely powers the product's own MCP server, which is a good sign it is maintained rather than abandoned. Marked down slightly because public rate-limit and SDK documentation is thin, so you build your own client. A 7 out of 10 for anyone wiring Buffer into a custom pipeline.
Strong agent fit through a first-party MCP server. Buffer hosts an official MCP server at mcp.buffer.com with native setup docs for Claude, ChatGPT, Cursor, and Perplexity, layered on a modern GraphQL API that is now open on every plan. The gaps are real: no official OpenAPI spec or maintained SDKs, so deeper custom work leans on the GraphQL schema directly. For no-code agent posting across 11 networks, though, the MCP path is genuinely first-party.
