Model Context Protocol
Connect AI assistants and agents directly to your Scheduler Zero workspace.
# Model Context Protocol
For a terminal workflow, use the [Scheduler Zero CLI](/cli) and its
[command reference](/cli/commands); for direct integrations, use the
[REST API](/rest-api). The [MCP Markdown index](/mcp/llms.txt),
[tool-only index](/mcp/tools/llms.txt) and [complete MCP text](/mcp/llms-full.txt)
provide the same documentation without browser rendering. Every page offers
**Copy as Markdown**; see [Markdown formats](/markdown).
Scheduler Zero provides a hosted [Model Context Protocol](https://modelcontextprotocol.io) server at:
```text
https://mcp.schedulerzero.com/mcp
```
The server exposes capabilities from the shared API contract as MCP tools. Browse [all callable tools and their schemas](/mcp/tools). Capabilities may combine several REST operations into one goal-oriented tool.
> Use WorkOS AuthKit in interactive desktop clients. Use a personal Scheduler Zero API key in headless agents, CI, and cloud workspaces.
## What you can do
- Discover the Workspaces your credential can access.
- Pass an explicit Workspace handle on each data call.
- Create and manage campaigns, sequences, leads, inboxes, warmup, tasks, templates, workflows, verification runs, domains, webhooks, and workspace settings according to your granted permissions.
- Read and triage the unified inbox — list threads, fetch message bodies and attachments, reply, archive, star, and set reminders.
- Run the dialer: call lists, power-dial sessions, dispositions, recordings, and voicemail drops.
- Manage workspace members, invitations, and custom roles.
- Run private-alpha read-only SQL queries when the credential includes the `sql` scope.
To find a tool by intent without connecting to Workspace data, use the public [documentation MCP and find_tools](/mcp/discovery).
Continue to [Connect a client](/mcp/connect) for setup examples.
