Centinela continuously watches the third-party MCP servers your AI agent depends on — public catalog and your own private servers — and alerts you with a clear explanation the moment something changes.

An MCP server can behave well for months and change overnight.
In September 2025, the maintainer of the official Postmark MCP server added a hidden BCC copy of every email sent to an address controlled by an attacker. It was installed as a trusted tool and changed later, without telling anyone.
A 2026 scan of 1,808 MCP servers found that 66% had a real security finding — command injection, path traversal, hidden instructions in a tool's description.
The official MCP registry went from 100,000 downloads a month to over 97 million in a year and a half. The more third-party servers your agent connects to, the more unmonitored attack surface.
From public catalog to an actionable alert, without you having to check a dashboard every day.
Every hour, without you asking — thousands of MCP servers from the official registry, compared against their previous state.
Private servers or ones that require authentication, with your own encrypted token — we never see it in plain text, or share it with anyone.
Not just "something's different": a plain-language explanation of whether the change is reasonable or suspicious, and why.
By email, querying the API from your own system, asking your agent directly with our MCP server, or with a webhook to your own system (Slack, PagerDuty…).
Every server has its full evolution — when it changed, what changed, and whether it had happened before.
With your own credential, encrypted at rest. It doesn't need to be public for us to watch it.
Every alert says why in plain language — to decide in seconds, not to investigate for half an hour.
API with your own key on any plan, or ask your agent directly with our MCP server — paid plans.
