Rate-limit errors carry retry_after_seconds, bulk deletes validate every key first, and the docs say which repeated calls are safe (15). No SLA found (0). Not labelled beta (10). 20 + 5 + 5 + 15 + 0 + 10 = 55.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 80 (checked 2026-11-07): Every tool's input schema declares additionalProperties false, and the docs call tools/list the field-level reference (25). llms.txt and .md pages for agents (10). Detailed tool guidance, including which to start with and what not to request (18 of 20). Typed inputs with enums, required combinations and no untyped data objects (15). A table of JSON-RPC error codes with their data fields, and worked calls (12 of 15). No public changelog found (404) (0). 25 + 10 + 18 + 15 + 12 + 0 = 80.\n- Agent ergonomics 73 (checked 2026-11-07): 71 tools (5), with four task-oriented tools and summary modes that cap list output (5 back). Summary mode defaults to 25 rows, allows 100 and returns next_page (20). Documented, recoverable errors (18 of 20). Safety metadata in each tool schema and documented repeat behaviour (15 of 20). setup_monitor takes few fields; SDKs and a CLI (10 of 15). 10 + 20 + 18 + 15 + 10 = 73.\n- Security \u0026 auth 58 (checked 2026-11-07): OAuth bounded by role with no scope choice, or scoped API keys (22 of 30). Read-only users get only read tools; write tools follow the role (14 of 20). The docs warn that event messages, command output and request bodies can hold customer data or secrets, and tell the agent to ask before expanding them; secrets are redacted (12 of 15). No audit log of MCP calls found (0). The security page covers encryption and relies on AWS's certifications; no security.txt (404) and no disclosure policy found (10 of 20). 22 + 14 + 12 + 0 + 10 = 58.\n- Payments \u0026 pricing 40 (checked 2026-11-07): No machine payment protocol (0). Per-monitor and per-user prices public (20). Free plan for 5 monitors, no card mentioned (20). A person signs up or signs in through a browser (0). 0 + 20 + 20 + 0 = 40.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 55 (checked 2026-11-07): Registry entry io.cronitor/cronitor updated 3 November 2026 (30). No dated changelog found to count (0). Support page and docs; no public changelog (10 of 15). Official registry entry under its own namespace, and official SDKs (15). No package to read (0). 30 + 0 + 10 + 15 + 0 = 55. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.\n- Transparency \u0026 trust 37 (checked 2026-11-07): robots.txt disallows the terms and privacy pages, so neither was read (5 of 30, terms exist but weren't readable). Data handling only from the security page (encryption, backups) (10 of 30). No deprecation policy found; the docs version the error codes by protocol revision (5 of 20). Subprocessors not found (5 of 20). 5 + 10 + 5 + 5 = 25.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (15 items).

The badge or a plain link to this page verifies the listing, from a page on cronitor.io or one of its subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"cronitor-mcp\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp.
