Scheduler Zero documentation
Connect AI agents with MCP or build directly on the Scheduler Zero REST API.
Scheduler Zero exposes two integration surfaces backed by the same workspace-scoped permissions.
Connect with MCP
Give Claude, Codex, Cursor, and other MCP clients access to Scheduler Zero tools.
Use the REST API
Create campaigns, manage leads, subscribe to webhooks, and query your workspace.
Download OpenAPI
Use the machine-readable OpenAPI 3.1 contract in your own SDK or tooling.
Before you begin
Create an API key under Settings → API Keys in the Scheduler Zero app. Each key belongs to one workspace and only grants the permission scopes you select.
Interactive MCP clients can use Google OAuth instead, so you do not need to copy a key into a desktop application.
