xserver-files-operator

xserver-files-operator is a skill for Codex from mocchalera/xserver-files-mcp. It costs 64 tokens per session (1,033 once invoked), scanned A, original, MIT.

A set of operating instructions for safely using the XServer files MCP server and command-line tool to manage website files over SFTP.

In plain words
What is it for?
Use it for reading or writing XServer files, editing website workspaces, managing .htaccess files, and creating domain redirects.
Why use it?
It prevents risky operations by enforcing configured domain roots, dry runs, backups, and careful handling of keys, passwords, and site files.

Skill for Codex

Written for Codex: agents/openai.yaml present.

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/YOU/.config/xserver-files-mcp/config.json.

Good fit Use it for reading or writing XServer files, editing website workspaces, managing .htaccess files, and creating domain redirects.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xserver-files-operator scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

XServer Files Operator

Overview

Use this skill to work with the local MCP/CLI in this repository without bypassing its safety model. The MCP connects to XServer over SFTP on port 10022, restricts paths to configured domain roots, and backs up existing files before writes by default.

Safety Contract

  • Treat ~/.config/xserver-files-mcp/config.json as the operator-owned config; keep only config/example.config.json in the repo.
  • Keep private keys under ~/.ssh/, not in this repository.
  • Use server_id for multi-server work; omit it only when the default server is intended.
  • Use configured domains such as old-site.example.com; do not pass absolute remote paths to tools or CLI commands.
  • Run dry-run first for redirect and write workflows unless the user explicitly asks for an immediate write.
  • Keep backups enabled unless the user explicitly accepts the risk.
  • Keep local site workspaces outside this repository, normally under ~/Dev/xserver-sites.
  • Use workspace pull/push for edited site files; do not clone WordPress/site trees into this tool repository.
  • Treat wp-config.php, uploads, logs, backups, SQL/database dumps, and archives as default-excluded workspace paths unless the user explicitly accepts the risk.
  • Understand that replaceInFile and set_domain_redirect are not atomic: they read, transform, and write in separate SFTP calls. If another operator edits the same file concurrently, their changes may be lost. Coordinate access or use pull/push workflow for critical edits.

Local Checks

Install and test:

npm install
npm test

Check config parsing without connecting to XServer:

XSERVER_FILES_CONFIG=config/example.config.json node src/cli.js servers

Create a domain workspace outside the repository:

node src/cli.js workspace old-site.example.com

Pull one file for local editing:

node src/cli.js pull old-site.example.com .htaccess

Push the matching workspace file back with a dry-run first:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
