What's the difference between scheduled and on-demand tasks?
Scheduled tasks include a cron expression and run automatically on that schedule. On-demand tasks omit the schedule and sit idle until triggered via the `run_task` tool.

概览
What is MCP Cron?
MCP Cron is a Model Context Protocol server for scheduling and managing tasks through a standardized API. It supports shell commands, AI-powered tasks, and HTTP webhook tasks, with task persistence across restarts via SQLite. It's intended for developers and AI agents that need to schedule recurring or on-demand work.
How to use MCP Cron?
Install via npx -y mcp-cron and configure it in your MCP client's config file (e.g., ~/.cursor/mcp.json or Claude Desktop's config). The server supports two transport modes: HTTP (Streamable HTTP, default) and stdio. Key command-line arguments include --transport, --ai-provider, --ai-model, --db-path, and --prevent-sleep.
Key features of MCP Cron
- Schedule shell command, AI, or HTTP tasks using cron expressions
- AI tasks can use other MCP servers via a config file
- Manage tasks (add, list, run, update, remove) via MCP protocol
- Task execution with output capture and result history
- Task persistence across restarts using SQLite
- Multi-instance safe — multiple instances can share the same database
Use cases of MCP Cron
- Schedule recurring system administration scripts or maintenance commands
- Have an AI agent periodically analyze data and provide summaries
- Trigger HTTP webhooks on a cron schedule for API polling or health checks
- Run on-demand tasks (without a schedule) for ad-hoc execution via
run_task
常见问题
What transports does MCP Cron support?
It supports HTTP (Streamable HTTP, the default) and stdio. HTTP is for browser/network clients; stdio is for direct piping and inter-process communication.
How does sleep prevention work?
On macOS and Windows, the `--prevent-sleep` flag prevents the system from going idle while MCP Cron is running. It uses `caffeinate` on macOS and `SetThreadExecutionState` on Windows. Linux is not supported for sleep prevention.
What database does MCP Cron use for persistence?
It uses a local SQLite database. The default path is `~/.mcp-cron/results.db`, configurable with the `--db-path` flag or `MCP_CRON_STORE_DB_PATH` environment variable.
How do I configure AI providers for AI tasks?
Use `--ai-provider` (openai or anthropic) and `--ai-model` flags, or their corresponding environment variables. API keys are set via `OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, or the generic `MCP_CRON_AI_API_KEY`. A custom base URL (`--ai-base-url`) supports OpenAI-compatible endpoints like LiteLLM.
