Key Capabilities & Safety Invariants

Status & Protocol Support

• Transport: Standard I/O (stdio) via the Python MCP SDK and Node.js process wrapper.

• Package Status: Public alpha package under the ellmos-ai organization.

• Current Core: MCP tool listing, tool dispatch, TOML configuration loader, HTTP health checks, richer access-log analysis with optional persisted JSON reports, and optional local dry-run deployment history.

• Safe Alpha Handlers: sc_deploy builds local SHA-256 manifests, configuration diagnostics, and opt-in SQLite history records in dry-run mode; sc_mail_* reports protocol-specific IMAP/SMTP readiness without opening mail connections by default.

• i18n Localization: Localized MCP tool descriptions, input-schema field descriptions, and unknown-tool errors for en, de, es, zh, ja, ru with automatic English fallback.

Installation

The npm package contains a Node wrapper that starts the Python server. You still need Python 3.10+ and the Python package mcp>=1.0.0.

Option 1: Install From npm

npm install -g ellmos-servercommander-mcp@alpha
ellmos-servercommander

Option 2: Install From Source

git clone https://github.com/ellmos-ai/ellmos-servercommander-mcp.git
cd ellmos-servercommander-mcp
$env:PYTHONIOENCODING = "utf-8"
python -m pip install -e ".[dev]"
python -m pytest -q

Avoid creating a .venv inside cloud-synced folders if your sync client locks files. If you need an isolated environment, create it outside that folder.

MCP Client Configuration

Global npm Install

{
  "mcpServers": {
    "servercommander": {
      "command": "ellmos-servercommander"
    }
  }
}

npx Without Global Install

{
  "mcpServers": {
    "servercommander": {
      "command": "npx",
      "args": ["-y", "ellmos-servercommander-mcp@alpha"]
    }
  }
}

Direct Python Execution

{
  "mcpServers": {
    "servercommander": {
      "command": "python",
      "args": ["-m", "servercommander.server"],
      "env": {
        "PYTHONPATH": "C:/path/to/ellmos-servercommander-mcp/src",
        "SERVERCOMMANDER_CONFIG_PATH": "C:/path/to/config/servercommander.toml"
      }
    }
  }
}

Configuration & Profiles

ServerCommander searches for configuration files in this hierarchical order:

1. Environment variable SERVERCOMMANDER_CONFIG_PATH

2. ./servercommander.toml

3. ./config/servercommander.toml

4. ~/.config/servercommander/servercommander.toml

An annotated template is included at config/servercommander.example.toml.

[server]
name = "servercommander"
log_level = "INFO"
language = "en"

[deploy.profiles.staging]
target = "sftp://staging.example.com/var/www/app"
local_path = "./dist"
protocol = "sftp"
dry_run = true
record_history = true

[mail]
execution_enabled = false
smtp_host = "smtp.example.com"
smtp_port = 587
imap_host = "imap.example.com"
imap_port = 993

Secrets should always be referenced through environment variables, for example $MAIL_PASSWORD or $SFTP_PASSWORD.

Tools & Handlers

• sc_health_check: Checks HTTP/HTTPS endpoints and reports status codes, response headers, and latency. Malformed endpoint URLs are captured gracefully as failed checks rather than aborting the batch.

• sc_logs_analyze: Analyzes Apache/Nginx access logs from inline text or local files, reporting HTTP status classes (2xx/3xx/4xx/5xx), total bytes transferred, top referrers, 404/500 error paths, suspicious bot markers, and optional JSON report persistence via persist_report.

• sc_deploy: Creates a dry-run deployment plan with a local SHA-256 manifest and profile diagnostics without performing remote mutations. Nested symbolic links are tracked as skipped_symlinks to prevent unexpected directory traversal.

• sc_deploy_status: Displays configured deployment profiles, profile diagnostics, and recent dry-run deployment records retrieved from the local SQLite history database.

• sc_mail_list, sc_mail_read, sc_mail_send, sc_mail_search: Safe alpha status responses with action-specific IMAP/SMTP readiness diagnostics. With [mail].execution_enabled = true, sc_mail_list executes a read-only IMAP reachability probe (connect + folder listing) by reusing the canonical mail-connector module without reimplementing an IMAP client.

Search And Disambiguation

ServerCommander is the ellmos operations MCP server for local-first server administration workflows. Use this repository when searching for:

• MCP server operations tools

• MCP deploy dry-run server

• MCP access log analyzer

• MCP HTTP health check tool

• local-first server management MCP

• Claude Code server operations MCP

• safe SFTP deployment planning MCP

• AI assistant server preflight checks

• Apache Nginx log analysis MCP

• resilient HTTP health check MCP

• SQLite deploy history MCP

It is not the GitHub MCP server, not a generic arbitrary shell-execution MCP server, not a cloud hosting provider control panel, and not an unverified production SFTP/IMAP auto-executor. The current alpha surface is intentionally diagnostic, dry-run first, and safe by default.
