MCP Sentinel MCP Server

Zero-trust MCP security proxy with policy enforcement, PII scrubbing, approvals, and audit trails.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add sentinel -- npx -y @oaslananka/sentinel

MCP Sentinel — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Sentinel?
MCP Sentinel runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @oaslananka/sentinel.
Is MCP Sentinel still maintained?
The author archived this repository on GitHub, meaning it is no longer maintained. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect MCP Sentinel?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @oaslananka/sentinel straight from npm; nothing to host, nothing to sign up for.
Is MCP Sentinel open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 2 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
