tickstem/mcp

MCP server for Tickstem — exposes cron job scheduling, uptime monitoring, heartbeat monitoring, and email verification as native tools for AI coding assistants (Claude, Cursor, Copilot, and any MCP-compatible agent).

Let your AI assistant register cron jobs, create uptime monitors with response assertions, manage heartbeat monitors, verify email addresses, and query results — while you write the app code.

Claude Code

Add to your ~/.claude/claude_desktop_config.json (or equivalent):

{
  "mcpServers": {
    "tickstem": {
      "command": "tsk-mcp",
      "env": {
        "TICKSTEM_API_KEY": "tsk_your_key_here"
      }
    }
  }
}

Available tools

Cron jobs

Tool	Description
`list_jobs`	List all cron jobs in the account
`get_job`	Get a cron job by ID
`register_job`	Register a new cron job (name, schedule, endpoint)
`update_job`	Update an existing job — only provided fields change
`pause_job`	Pause a job so it no longer fires
`resume_job`	Resume a paused or failing job
`delete_job`	Permanently delete a job and its execution history
`list_executions`	List execution history for a job, most recent first

Uptime monitoring

Tool	Description
`list_monitors`	List all monitors — status, URL, interval, SSL expiry, assertions
`create_monitor`	Create a monitor with optional response assertions (status code, response time, body)
`get_monitor`	Get a monitor by ID
`pause_monitor`	Pause a monitor so it stops polling
`resume_monitor`	Resume a paused monitor
`delete_monitor`	Permanently delete a monitor and its check history
`list_monitor_checks`	List recent checks — status, HTTP code, duration, error, SSL expiry

Response assertions

create_monitor accepts an assertions parameter — a JSON array of conditions that must all pass for a check to be considered up. When assertions are set they replace the default 2xx/3xx logic.

Source	Valid comparisons	Target
`status_code`	`eq` `ne` `lt` `lte` `gt` `gte`	integer string
`response_time`	`eq` `ne` `lt` `lte` `gt` `gte`	integer string (ms)
`body`	`eq` `ne` `contains` `not_contains`	plain string

Heartbeat monitoring

Tool	Description
`list_heartbeats`	List all heartbeats — status, token, interval, grace window, last ping time
`create_heartbeat`	Create a heartbeat monitor (dead-man's switch)
`get_heartbeat`	Get a heartbeat by ID
`update_heartbeat`	Update name, interval, or grace window
`pause_heartbeat`	Suppress alerts during planned downtime
`resume_heartbeat`	Resume alerting after a pause
`delete_heartbeat`	Permanently delete a heartbeat and its ping history
`ping_heartbeat`	Record a successful job run — no API key needed, token is the credential
`list_heartbeat_pings`	List recent pings for a heartbeat, most recent first

Email verification

Tool	Description
`verify_email`	Check syntax, MX records, disposable domain, and role-based prefix
`list_verify_history`	List past verification results for the account

Environment variables

Variable	Required	Description
`TICKSTEM_API_KEY`	Yes	API key from app.tickstem.dev
`TICKSTEM_BASE_URL`	No	Override API base URL (e.g. `http://localhost:8080/v1` for local dev)

Local development

export TICKSTEM_API_KEY=tsk_your_key_here
export TICKSTEM_BASE_URL=http://localhost:8080/v1
go run ./cmd/tsk-mcp

SDKs

The MCP server handles infrastructure management from your AI assistant. For application code, use the SDK that matches your language:

Language	Install	Docs
Python	`pip install tickstem`	github.com/tickstem/python
Go (cron)	`go get github.com/tickstem/cron`	pkg.go.dev
Go (uptime)	`go get github.com/tickstem/uptime`	pkg.go.dev
Go (heartbeat)	`go get github.com/tickstem/heartbeat`	pkg.go.dev
Go (verify)	`go get github.com/tickstem/verify`	pkg.go.dev
Node.js	`npm install @tickstem/cron`	github.com/tickstem/node

All SDKs use the same API key.

Get an API key

app.tickstem.dev — free tier includes 1,000 cron executions, 5 uptime monitors, 5 heartbeat monitors, and 500 email verifications per month.
