Overview

AI-generated overview

Hosted MCP server that lets an assistant list, inspect, create, update and delete Cronitor monitors and send telemetry pings.

What you can do
  • List monitors with their current passing or failing status, paginated
  • Get full detail for one monitor, including latest event and invocations
  • Create, update or delete monitors, including changing schedules and pausing
  • Send telemetry pings (run, complete, fail, ok, pause) that record activity and can clear or trigger alerts
  • Check monthly tool-call usage, request a feature, upgrade or cancel a paid plan
When to use it
Useful when you want an assistant to answer questions like which scheduled jobs are failing right now, or to manage Cronitor monitors and report job heartbeats without leaving the chat.
Requirements
Remote endpoint at cronitor.usefulapi.io/mcp; no local install. Sign-in is via OAuth, and on first connect you paste your Cronitor API key, which is validated and stored per user. No API key or Authorization header goes in the client config.
Before you install
Create, update, delete and ping tools change Cronitor data; deletion is permanent and irreversible, and pings can clear or trigger alerts. The server is a paid third-party proxy: the free tier allows 50 tool calls a month, and paid plans are billed through Stripe checkout links. Your Cronitor API key is stored by the hosting provider.

Installation

In SourceWeft

  1. Open Cronitor MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fcronitor/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Cronitor MCP by usefulapi

Manage Cronitor monitors and send telemetry pings from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Cronitor API key.

Live endpoint: https://cronitor.usefulapi.io/mcp · Homepage: https://usefulapi.io/cronitor

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://cronitor.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http cronitor https://cronitor.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "cronitor": {      "url": "https://cronitor.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Cronitor credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/cronitor/

On first connect you'll paste your Cronitor API key. It's validated, stored per-user, and scoped to you.
