How this service works

MCP server monitoring API (6h checks, 30 days). Same as POST /v1/watch, but the server is re-audited every 6 hours for 30 days. HMAC-SHA256 signed webhook on tools/list fingerprint or grade changes (and unreachable/recovered). Returns watch_id, the signing secret (shown once) and the baseline. Never charged for unreachable or blocked URLs or a full watch list. Search intents: mcp server monitoring, mcp uptime, mcp tool change alerts, mcp webhook alerts, watch mcp server, mcp drift monitor.

Output

Returns a watch_id identifying the monitoring subscription, a one-time HMAC-SHA256 signing secret (whsec_ prefix, 64 hex chars) for verifying webhook payloads, a baseline snapshot (fingerprint pin, grade, score, tool count), an expiry timestamp 30 days out, and a status URL to check the watch state at any time.

Example use cases

MCP tool drift detection for production

“Start watching my production MCP server at https://mcp.mycompany.com/hub every 6 hours for 30 days and POST signed notifications to https://alerts.mycompany.com/webhook whenever the tools list or quality grade changes.”

Uptime alerting for third-party MCP dependency

“I rely on a third-party MCP server at https://partner.example.com/mcp — can you set up 6-hourly monitoring and have alerts sent to https://ops.myapp.com/hooks so I know immediately if it goes unreachable or its tools change?”

Baseline audit before MCP integration launch

“Before we go live, set up 6-hour checks on https://staging.aitools.co/mcp and send webhook events to https://ci.myteam.io/mcp-monitor — I want to know the baseline grade and catch any tool list changes during the validation window.”

Technical details

Endpoint

POSThttps://api.youraitools.co/toolfit/v1/watch/6h?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need frequent (every 6 hours) change detection on an MCP server — ideal for production dependencies or integrations where tool drift or downtime within a few hours is critical. Prefer over 24h monitoring when SLA requirements are tight or the MCP server is under active development. The 30-day window suits both short validation sprints and longer operational oversight without manual renewal.

Side effects

URL unreachable or blocked at registration — watch is not created and no charge is applied
Webhook URL is not publicly reachable on port 443 — notifications will fail silently or be retried
Invalid or non-HTTPS MCP server URL — request rejected
Malformed webhook URL — request rejected
Payment failure via x402 — endpoint returns 402 and no watch is created
Duplicate watch on the same URL/interval — may create a second subscription
