cron-mcp: Instructions file for Claude Code

CLAUDE.md

cron-mcp CLAUDE.md is an instructions file for Claude Code from Shreyas-Profile/cron-mcp. It costs 733 tokens per session, scanned A, original, MIT.

A repository-specific instruction file for deploying and maintaining the cron-mcp service on a Hetzner server. It documents the server location, Docker services, domain setup, tunnel routing, and required environment variables.

In plain words
What is it for?
Use it when deploying a new version, rebuilding the Docker services, connecting the cron.regiq.in subdomain, updating the Cloudflare tunnel, or configuring the service environment.
Why use it?
It gives coding agents the exact operational details needed to update this service without guessing its deployment layout. It also records a restriction against touching unrelated folders on the shared server.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions Claude Code.

This is Shreyas-Profile/cron-mcp's own configuration. It tells Claude Code how to work on cron-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cron-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cron-mcp CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Deploying cron-mcp to Hetzner + regiq.in

Deploy pattern for future Claude Code sessions working on this repo.

Server (shared with the rest of the Globalion MCP fleet)

  • SSH: [email protected]
  • Service directory: /opt/cron-mcp/
  • Domain: cron.regiq.in (Cloudflare-tunnelled to cron-mcp-web:3000)
  • Container names: cron-mcp-web, cron-mcp-db
  • NEVER touch other people's folders under /opt/ — see shreyas-onboarding.md §7.

Deploy a new version

From this repo on your dev machine:

tar --exclude=node_modules --exclude=.next --exclude=.git -cf - . \
  | ssh [email protected] "mkdir -p /opt/cron-mcp && tar -xf - -C /opt/cron-mcp/"
ssh [email protected] "cd /opt/cron-mcp && docker compose up -d --build"

First-time subdomain wiring (cron.regiq.in)

  1. Add an ingress rule to /opt/platform/cloudflared/config.yml on the server, BEFORE the final catch-all rule:
    - hostname: cron.regiq.in
      service: http://cron-mcp-web:3000
    
  2. Restart the tunnel: ssh [email protected] "docker restart platform-cloudflared-1"
  3. Create the DNS CNAME via the tunnel's own creds (no API token needed):
    ssh [email protected] "docker exec platform-cloudflared-1 cloudflared tunnel route dns 0caf1caf-59f6-4f36-9ea5-4aa9a9f41d0b cron.regiq.in"
    

Env vars

Populated on the server via /opt/cron-mcp/.env (NOT committed to git). Values live in shreyas-onboarding.md for shared secrets, per-app secrets are generated fresh:

  • GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET — created per-MCP in Google Cloud Console
  • NEXTAUTH_SECRETopenssl rand -base64 32
  • PUBLIC_BASE_URL=https://cron.regiq.in
  • NEXTAUTH_URL=https://cron.regiq.in

Health & debugging

curl https://cron.regiq.in/api/admin/health
ssh [email protected] "docker ps --filter name=cron-mcp --format 'table {{.Names}}\t{{.Status}}'"
ssh [email protected] "docker logs cron-mcp-web --tail 60"

Rules (from shreyas-onboarding.md §7)

  • No LLM in this stack. cron-mcp is a pure transport bridge — the user's agent supplies the model. If a future feature needs inference, route via OpenRouter with the shared Globalion key, never vendor APIs direct.
  • ✅ Expose /api/admin/health (already wired at src/app/api/admin/health/route.ts).
  • ✅ Container names prefixed with cron-mcp- and unique across the fleet.
  • ✅ Container-internal port is any port (3000 here); Cloudflare tunnel handles external HTTPS.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
