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
Read channels, ideas, queue and analytics; draft, create, edit, schedule and manage posts and ideas across supported social networks through Buffer's unified publishing layer
03 · Actions and write paths
Buffer's first-party MCP/agent surface includes state-changing tools in the documented capability area: Read channels, ideas, queue and analytics; draft, create, edit, schedule and manage posts and ideas across supported social networks through Buffer's unified publishing layer. The audit did not enumerate every mutation; verify the current tool catalog and require explicit confirmation for consequential actions.
04 · Authentication and permissions
Official Buffer developer and support pages confirm a hosted endpoint with API-key or integration-specific OAuth access. Existing vendor identity, account, tenant, and permission controls should be treated as the authorization boundary.
05 · Monitoring, approval, and recovery
Official Buffer developer and support pages confirm a hosted endpoint with API-key or integration-specific OAuth access. Publishing is consequential and network-specific API limitations remain; use Buffer drafts/approval workflows where available rather than treating every post as automatically publishable.

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.
