License: MIT Python 3.11 Docker

A Linux MCP server for remote administration over SSH. Diagnose, inspect, and manage any Linux host from Cursor, Claude Code, Codex, or any MCP (Model Context Protocol) client. Connects using per-user AD credentials elicited at runtime. Passwords live only in server memory with an idle TTL and are never logged.

  • 45+ tools: filesystem, systemd services, Docker, JBoss/WildFly discovery and log search, network, certificates, firewall, and more

  • Per-user AD identity: each request carries an X-AD-User header; the password is either supplied via the optional X-AD-Password header (no prompt) or elicited once and cached in-memory

  • Optional sudo elevation: privileged commands require an explicit elevate_sudo call; the sudo password is prompted, or reuses X-AD-Password when supplied

  • Zero secrets on disk: no credentials in config files, env vars, or logs

Example prompts

  • "Why is the disk almost full on host1? What's eating the space?"

  • "The myapp service keeps crashing, check the journal logs and tell me why."

  • "Grep the JBoss server log for OutOfMemory errors from today."

  • "Which process is listening on port 8443?"

  • "Is the TLS certificate on host1:443 close to expiry?"

  • "Tail the logs of the nginx Docker container."

  • "Restart the httpd service and confirm it came back up."

Quick Start

docker compose -f docker-compose.yml -p linux-ssh-mcp up -d --build --force-recreate

Client setup

X-AD-User is required. X-AD-Password is optional: omit it and the server prompts for the password once via MCP elicitation, caching it in memory.

Cursor (mcp.json)

{
  "mcpServers": {
    "linux-ssh-mcp": {
      "type": "http",
      "url": "http://localhost:8006/mcp",
      "headers": {
        "X-AD-User": "<your-ad-username>",
        "X-AD-Password": "<your-ad-password>"
      }
    }
  }
}

Claude Code

claude mcp add --transport http linux-ssh-mcp http://localhost:8006/mcp \
  --header "X-AD-User: <your-ad-username>" \
  --header "X-AD-Password: <your-ad-password>"

Codex (~/.codex/config.toml)

[mcp_servers.linux-ssh-mcp]
url = "http://localhost:8006/mcp"
http_headers = { "X-AD-User" = "<your-ad-username>", "X-AD-Password" = "<your-ad-password>" }

Any other MCP client works the same way: point it at the streamable HTTP endpoint and pass the headers.
