Where they pull apart

Buffer

Stands out: MCP is included on the free plan, so Claude or ChatGPT can draft and queue posts without a paid seat.

Watch out: The $5 figure is per channel on yearly billing; monthly costs more. Free caps you at 10 scheduled posts per channel and one user.

Not the right fit for

Newsrooms that need a full social suite beyond scheduling
Users who only want LinkedIn commenting, not a multi-network queue

Supergrow

Stands out: Postcast turns a short AI interview into several LinkedIn posts, and Pro adds a Supergrow MCP server for Claude or ChatGPT.

Watch out: Starter caps Postcast at 2 sessions and leaves out carousels, analytics and MCP. Those need Pro at $39/mo.

Not the right fit for

Social teams that post to many networks
Buyers who want MCP on the cheapest plan
