listing.about

SentinelX exposes your Linux, macOS and Windows machines as MCP tools. An assistant can run allowlisted shell commands, read, search and edit files, manage services, and upload files. Commands and filesystem paths must be permitted in a local config, and every action is recorded.

It runs as a hosted hub at mcp.sentinelx.app (streamable HTTP, OAuth sign-in with Google) plus an agent you install on each host. The agent opens a single outbound WebSocket to the hub, so no inbound ports are needed. The agent source is Apache-2.0; the hub is closed source.

listing.can

  • Run allowlisted shell commands on enrolled hosts
  • Read, list and search files with regex and glob filters
  • Edit, move, copy and delete files with structured operations
  • Start, stop, restart and check systemd services
  • Upload large files to a host in chunks
  • Inspect host policy and capabilities
  • Manage multiple hosts through one hub

listing.tools

listing.notools.oauth

listing.prompts

  • Check disk usage and memory on my production server.

  • Restart the nginx service and show its status.

  • Search /etc/nginx for every server_name directive.

  • Read the last 100 lines of /var/log/syslog on my web host.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http sentinelx https://mcp.sentinelx.app/mcp/mcp
  1. Start Claude Code, type /mcp, pick sentinelx and choose Authenticate. A browser window opens for the Pensa (pensados) sign-in.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

  1. Open Settings → Connectors and click Add custom connector.
  2. Name it SentinelX and paste this URL:
https://mcp.sentinelx.app/mcp/mcp
  1. Click Add, then Connect, and sign in when Pensa (pensados) asks.

Claude Desktop's JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

  1. Open the connector form on claude.ai. This button fills in the name and URL for you:
  1. Check that the URL reads https://mcp.sentinelx.app/mcp/mcp and click Add.
  2. Click Connect and sign in when Pensa (pensados) asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

  1. On chatgpt.com, open Settings → Security and login and turn on Developer mode.
  2. Go to chatgpt.com/plugins and click + to create an app for a remote MCP server.
  3. Paste https://mcp.sentinelx.app/mcp/mcp as the server URL and choose OAuth. ChatGPT sends you to Pensa (pensados) to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

Cursor

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "sentinelx": {
      "url": "https://mcp.sentinelx.app/mcp/mcp"
    }
  }
}

Cursor shows Needs login next to the server. Click it to sign in.

VS Code

Or from a terminal:

code --add-mcp '{"name":"sentinelx","type":"http","url":"https://mcp.sentinelx.app/mcp/mcp"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json
{
  "servers": {
    "sentinelx": {
      "type": "http",
      "url": "https://mcp.sentinelx.app/mcp/mcp"
    }
  }
}

VS Code asks you to sign in the first time the server starts.

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "sentinelx": {
      "serverUrl": "https://mcp.sentinelx.app/mcp/mcp"
    }
  }
}
  1. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add sentinelx --url https://mcp.sentinelx.app/mcp/mcp
codex mcp login sentinelx

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.sentinelx]
url = "https://mcp.sentinelx.app/mcp/mcp"

Gemini CLI

gemini mcp add --transport http sentinelx https://mcp.sentinelx.app/mcp/mcp

Then, inside Gemini CLI, run /mcp auth sentinelx to sign in.

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI's settings file.

{
  "mcpServers": {
    "sentinelx": {
      "type": "http",
      "url": "https://mcp.sentinelx.app/mcp/mcp"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://mcp.sentinelx.app/mcp/mcp.

listing.faq

Can I paste mcp.tc/i/sentinelx into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://mcp.sentinelx.app/mcp/mcp, so your client talks to SentinelX directly. The sign-in token only works there anyway. The quick link is for sharing: it opens this page, with setup steps for every client.

Does SentinelX need an API key or a sign-in?

Yes, you need a Pensa (pensados) account. The first time your client connects, it opens Pensa (pensados)'s sign-in page. The token goes straight to the server's own URL, never through mcp.tc.

Is SentinelX a remote or a local server?

Remote. Pensa (pensados) hosts it at https://mcp.sentinelx.app/mcp/mcp, and it speaks Streamable HTTP. There's nothing to install.

What can SentinelX do?

You can run allowlisted shell commands on enrolled hosts, read, list and search files with regex and glob filters and edit, move, copy and delete files with structured operations.

Which clients can use it?

Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT in developer mode, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.

Who wrote this page?

mcp.tc's robot read SentinelX's own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can't confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.
