Vantaj uptime monitoring via MCP — manage monitors, heartbeats, incidents, and status pages.
Do not connect
The assessed surface is high-risk. Remediate the findings before connecting.
Scanned 25 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The vantaj MCP server exposes 13 tools, focused primarily on general-purpose capabilities. Its published description reads: "Vantaj uptime monitoring via MCP — manage monitors, heartbeats, incidents, and status pages". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates vantaj D — the assessed surface is high-risk and should be remediated before use. Its most notable findings include "Data-exfiltration parameters" and "Data-exfiltration parameters". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check vantaj's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add vantaj to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
List all projects in the workspace. Call this first - most other tools need a project_id.
List uptime monitors in a project, with current status, response time, and 24h uptime.
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.

Get a single monitor by ID, including status, uptime, regions, and settings.
Create a new uptime monitor. Checks start immediately. Types: http, tcp (host:port URL), smtp, ping, ssl, dns. Set inverted=true for exposure monitoring (alert when a target that should stay down beco
Update a monitor's settings (name, url, interval, inverted, …). Cannot delete.
Pause a monitor - checks stop until it's resumed. Use before planned work on a single target.
Resume a paused monitor - checks start again immediately.
Schedule a one-time maintenance window: the listed monitors keep running but their alerts are suppressed between starts_at and ends_at. Use before deploys or planned downtime.
List heartbeat (cron/background job) monitors in a project, with last-ping status.
List incidents (outages) in a project - open and resolved, with timestamps and duration.
