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

create-http-monitor scanned grade A with 0 findings 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 12d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create an HTTP monitor

Preflight — read first. If you cannot see any uptimerobot:* MCP tools in your tool list, invoke the uptimerobot:setup skill before doing anything else. Do not tell the user the MCP is misconfigured — setup's Step 0 detects the common case (server connected, tools loaded after session start) and resolves it without re-keying.

Use when the user wants to monitor a website or HTTP(S) endpoint for reachability and/or specific response codes. HTTP is the default choice unless the user needs content matching (KEYWORD), response assertions (API), or low-level connectivity (PING / PORT).

Tool: create-monitor Required params: friendlyName, type: "HTTP", url (must be a full URL with scheme).

Minimal call

{
  "friendlyName": "Production API",
  "type": "HTTP",
  "url": "https://api.example.com/health"
}

Common optional params

  • interval — seconds between checks (30–86400). Defaults to the plan's default. Free-plan minimum is higher than paid plans.
  • timeout — request timeout in seconds (1–60).
  • httpMethodType — one of HEAD, GET, POST, PUT, PATCH, DELETE, OPTIONS.
  • authTypeNONE (default), HTTP_BASIC, DIGEST, BEARER. Pair with httpUsername / httpPassword.
  • customHttpHeaders — object, e.g. {"X-Source": "uptimerobot"}.
  • successHttpResponseCodes — array of strings that count as success, e.g. ["200", "201", "2xx"].
  • followRedirections — boolean, defaults to true.
  • checkSSLErrors — boolean, validates cert errors when true.
  • sslExpirationReminder / domainExpirationReminder — boolean flags for expiry alerts.
  • responseTimeThreshold — milliseconds; 0 disables slow-response alerts.
  • assignedAlertContacts — see below.
  • tagNames — array of tag strings (max 20, ≤50 chars each).
  • maintenanceWindowsIds — array of maintenance window IDs.

Alert contacts

"assignedAlertContacts": [
  { "alertContactId": "10", "threshold": 0, "recurrence": 0 },
  { "alertContactId": "20", "threshold": 5, "recurrence": 30 }
