API & MCP reference / Getting started

Introduction

REST base URL
https://posttrain.app/api/v1
MCP server
https://posttrain.app/api/mcp

Post Train exposes two programmatic surfaces over the same engine that powers the dashboard: a REST API for scripts, backends, and CI, and an MCP server for AI agents like Claude. Anything you can schedule by hand you can schedule over either one.

Both are included with every paid plan — Creator, Growth, and Pro. There is no separate API purchase.
