Postgale vs the Buffer API
Buffer is a social media scheduling app for people, with a calendar, a community inbox for comments, analytics and a developer API that it says works with Claude, ChatGPT, Cursor, Raycast and Perplexity. Its approval workflows are a Team plan feature for teammates. Postgale is built for the agent as the user: an MCP server and REST API, approval that a person sets per workspace, account, key or app, a queue for replies and DMs as well as posts, and an audit log. Buffer covers more channels and is far cheaper to start.
What is the difference between Postgale and Buffer?
Postgale is the secure layer for AI agents on social media. Agents publish through its REST API and MCP server; a person decides where approval applies, and every write is recorded in an audit log.
Buffer is a scheduling and engagement app priced per channel, with a free plan. Its developer site says “Connect Buffer to your agents, automation tools, or build something entirely new”, with API keys used as bearer tokens, and its pricing page lists integrations for ChatGPT, Claude, Cursor, Perplexity, Raycast, n8n, Make and Zapier. API access comes with every plan, with request limits per plan.

| Agent access | Hosted at postgale.com/mcp (Streamable HTTP); 70 tools, each annotated as read-only, write or destructive. OAuth 2.1 sign-in, so ChatGPT, claude.ai, Claude Desktop, Claude Code, Cursor and VS Code connect with the URL alone; or an API key as a bearer header (n8n, OpenClaw, Hermes Agent, your own agent). Sign-in tokens work on the MCP server only; the REST API uses API keys | Developer API with bearer-token API keys; listed integrations for ChatGPT, Claude, Cursor, Perplexity, Raycast, n8n, Make and Zapier; a “Social Media MCP” page is linked from its footer |

When should you pick Buffer, and when Postgale?
Pick Buffer if people do most of the work and an agent helps: a visual calendar, a queue, ideas, a comment inbox, reports and a large channel list, starting free. Its Team plan adds approval workflows between teammates.
Pick Postgale if the agent itself is the user: if a person, not the agent, must decide what needs approval and the agent cannot switch it off; if replies, comment moderation and direct messages should wait in the same queue as posts; and if you want an audit log of every agent action from day one. Postgale also handles direct messages on Instagram, Messenger and WhatsApp.
