PostSider
1 commentThe first launch from PostSider
PostSider is a social calendar for 30+ networks with a drag-and-drop queue, plus an agent bridge over MCP, REST, and SDKs so Claude, Codex, Cursor, or any MCP agent can draft, schedule, and publish without per-platform glue code. Channel tokens use AES-256-GCM encryption. Flat pricing starts at $20/mo for 5 channels; 7-day full trial with no credit card. Solo founder Lukasz Blania builds and supports it from Poland under Lumi Zone.

Buffer-class schedulers still treat agents as an afterthought. PostSider puts the same calendar in front of a human and an MCP agent, which is the useful split if you actually want an agent to fill the queue.
The $20 flat five-channel plan and the "no glue code" MCP pitch are what pulled me in. I have not connected a live Instagram token yet; that is the first real test.
