What is the Cronitor (Cron Monitoring) MCP Server?
Connect Cronitor to your AI agent to gain full visibility into your background jobs, heartbeats, and website uptime through natural conversation.
What you can do
- Monitor Management — List, create, and update monitors for cron jobs, heartbeats, and health checks across your entire infrastructure.
- Real-time Telemetry — Send pings and job state updates (run, complete, fail) directly to track execution lifecycles.
- Performance Insights — Query metrics, aggregates, and site analytics to understand latency, success rates, and system health.
- Incident Response — Track active issues, manage status pages, and create maintenance windows to silence alerts during deployments.
- Infrastructure Control — Organize monitors into groups, manage notification settings, and audit API keys.
How it works
- Subscribe to this server
- Enter your Cronitor API Key
- Start monitoring your stack from Claude, Cursor, or any MCP-compatible client
No more jumping between dashboards to check if your nightly backups finished or why a heartbeat is missing. Your AI acts as a 24/7 SRE assistant.
Who is this for?
- DevOps Engineers — instantly check monitor statuses and silence alerts during maintenance without leaving the terminal.
- Backend Developers — verify cron job performance and send telemetry pings directly from the code editor.
- SRE & Ops Leads — manage status pages and track incident history across multiple environments.

Frequently asked questions
How can I manually signal that a job has finished successfully?
You can use the send_telemetry tool. Provide the monitor_key and set the state to 'complete'. This will immediately update Cronitor with the job's success status.
Is it possible to silence alerts for a specific monitor during maintenance?
Yes! Use the pause_monitor tool with the monitor_key and the number of hours you want to pause it. Alternatively, use create_maintenance_window for broader scheduling.
How do I check for recent errors on my monitored websites?
Use the get_site_errors tool. It retrieves the most recent error logs and failure details for a specific site monitor, helping you debug downtime quickly.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
