# PostSteward

> Agent-first social publishing infrastructure. An authorised agent gets scoped operations over remote MCP or HTTP, browser WebMCP in a connected workspace, and durable receipts for publication attempts to X, Threads and LinkedIn.

## Public showcase status

## Agent transports

- Remote MCP: `<POSTSTEWARD_SERVICE_ORIGIN>/mcp` with `Authorization: Bearer <agent token>`.
- HTTP: `POST <POSTSTEWARD_SERVICE_ORIGIN>/api/operations/{operation}`.
- CLI: shell/cURL calls use the HTTP operation surface.
- WebMCP: a connected workspace registers the same scoped catalogue through `document.modelContext` in a supported browser.

## Plans

Free: publishing, explicit scheduling, routing, receipts, on-demand metrics and all agent transports.
Advanced: USD 5/workspace/month for source monitoring, replenishment, rolling allocation, spacing controls and scheduled metrics.
