Buffer accounts, organizations, connected social channels, queued, scheduled, and draft posts, publishing queues, and reusable content ideas governed by post and idea scopes.
Buffer
Buffer
Buffer belongs in Atlas because its hosted MCP turns channel, queue, draft, and post management into agent actions across connected social accounts through one publishing layer.

Concrete capability record
Data, retrieval, actions, identity, and operating limits
A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
List connected channels, inspect queued or draft posts, retrieve account and organization context, and read content ideas where the granted scope allows.
03 · Actions and write paths
Create and manage posts or ideas, add content to a channel queue, and schedule publication through Buffer's connected social accounts and unified publishing model.
04 · Authentication and permissions
Generic MCP clients use a bearer API key; registered integrations can use OAuth 2.0 with PKCE and explicit scopes for post, idea, account, or offline access.
05 · Monitoring, approval, and recovery
OAuth can restrict capabilities by scope and users can revoke access. Account API keys are broader, reaching every organization and channel available to that Buffer account.
06 · Limits and caveats
Buffer does not support per-organization API-key scoping. The short MCP page gives examples rather than a complete tool catalog, and network-specific post fields still depend on connected channels.

Official MCP serverBuffer-hosted remote MCPCurrent documented service
Support: Official MCP server
Read scope: Inspect channels, organizations, queues, scheduled or draft posts, and ideas through the hosted server within the authenticated account or OAuth scopes.
Write scope: Create and manage ideas or social posts, place posts into queues, and schedule them for connected channels when the credential includes the required write scope.
Authentication: Connect generic MCP clients to Buffer's hosted HTTP endpoint with a bearer API key; registered apps may instead use OAuth Authorization Code with PKCE and user consent.
Approval boundary: Prefer creating a draft for review before placing content in a queue or scheduling publication; account-wide keys require extra care when several organizations or brands share one account.
Protocol does not erase product boundaries.
Confirm the current tool catalog, plan, region, scopes, rate limits, terms, and write behavior before implementation.

Single-platform patterns
- Lean social calendar and publishing cockpit
- Social publishing command center
- Brand-signal briefing
- Response and escalation queue
Multi-platform compositions
- Buffer + content-production platform: social publishing command center
- Buffer + CRM or support system + analytics or work-management system: cross-system decision workspace
Evidence and dates
First-party references, with publisher and review dates separated
“Publisher updated” is shown only when the page exposes an update date. “BYO-UI reviewed” records when this research checked the reference. A missing publisher date is reported as missing—not replaced with the review date.
