Seren-Cron Integration

Use seren-cron to run this skill on a schedule — no terminal windows to keep open, no daemons, no permanent computer changes required. Seren-cron is a cloud scheduler that calls your local trigger server on a cron schedule.

Requirements: Seren Desktop login or a valid SEREN_API_KEY.

Step 1 — Check seren-cron is available

Before scheduling, verify the publisher is reachable using mcp__seren__call_publisher:

publisher: seren-cron
path:      /health
method:    GET

If this call fails, stop here and tell the user:

"The seren-cron service could not be reached. Please send this error to hello@serendb.com for support."

Step 2 — Review active cron jobs (always do this first)

Always check for existing scheduled jobs before creating a new one. A user may have forgotten a live job is already running.

publisher: seren-cron
path:      /jobs
method:    GET

If jobs for this skill already exist, show them to the user and ask:

"You have [N] active cron job(s) for this skill. Would you like to:

1. Keep them running (recommended if intentional)
2. Stop all and create a new schedule
3. Cancel"

Do not create a duplicate cron job without explicit user confirmation.

Step 3 — Start the local trigger server

Start the webhook server that seren-cron will call on each scheduled tick:

SEREN_API_KEY="$SEREN_API_KEY" python3 scripts/run_agent_server.py --config config.json --port 8080

This process runs in your terminal session. When you close the terminal, it stops — that is expected and correct. Seren-cron handles the scheduling; your local server handles execution.

Step 4 — Create the cron schedule

With the server running, create the scheduled job:

publisher: seren-cron
path:      /jobs
method:    POST
body: {
  "name":            "euler-vault-compound-live",
  "url":             "http://localhost:8080/run",
  "method":          "POST",
  "cron_expression": "0 */12 * * *",
  "timezone":        "UTC",
  "enabled":         true,
  "timeout_seconds": 60
}

Save the returned job_id — you need it to pause, resume, or delete the job later.

Step 5 — Manage the schedule

List all active jobs:

publisher: seren-cron, path: /jobs, method: GET

Pause:

publisher: seren-cron, path: /jobs/{job_id}/pause, method: POST

Resume:

publisher: seren-cron, path: /jobs/{job_id}/resume, method: POST

Stop permanently:

publisher: seren-cron, path: /jobs/{job_id}, method: DELETE

Insufficient Funds Guard

If a live trade or cycle fails because the trading balance or SerenBucks balance is too low to execute, immediately pause the cron job:

publisher: seren-cron, path: /jobs/{job_id}/pause, method: POST

Then tell the user:

"Automated trading has been paused: insufficient funds detected. Please top up your balance before resuming the schedule."

Never allow the cron to keep firing when there are no funds available to trade.
