UniPost's pricing is per post volume only. Every plan includes all features — no feature tiers, no upgrade pressure.

UniPost Exclusive

Built for the AI agent era

UniPost is the only social media API with native MCP Server support. Let Claude, GPT, or any AI agent post on behalf of your users — no code required.

// Claude Desktop config
// Claude Desktop config { "mcpServers": { "unipost": { "url": "https://mcp.unipost.dev/sse", "headers": { "Authorization": "Bearer up_live_xxx" } } } }
What this means:
  • AI agents can list connected accounts
  • AI agents can publish posts
  • AI agents can read analytics
  • No custom integration code needed
Zernio also has MCP support, but UniPost's is designed as a core developer API feature.
