Where to find your API key: Log into Crafty Controller → click your username (top right) → API Key tab → copy the token.

Overview

Crafty Controller exposes a REST API under /api/v2. All endpoints require Bearer token authentication. The API covers:

Python Helper Setup

Install dependencies first:

pip install requests urllib3

Base client to reuse everywhere:

import requests
import urllib3
import json

# Suppress SSL warnings if using self-signed cert (common on local Crafty installs)
urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

def crafty_get(path, params=None):
    """GET request to Crafty API."""
    url = f"{CRAFTY_BASE_URL}{path}"
    resp = requests.get(url, headers=HEADERS, params=params, verify=False)
    resp.raise_for_status()
    return resp.json()

def crafty_post(path, payload=None):
    """POST request to Crafty API."""
    url = f"{CRAFTY_BASE_URL}{path}"
    resp = requests.post(url, headers=HEADERS, json=payload or {}, verify=False)
    resp.raise_for_status()
    return resp.json()

def crafty_patch(path, payload=None):
    """PATCH request to Crafty API."""
    url = f"{CRAFTY_BASE_URL}{path}"
    resp = requests.patch(url, headers=HEADERS, json=payload or {}, verify=False)
    resp.raise_for_status()
    return resp.json()

def crafty_delete(path):
    """DELETE request to Crafty API."""
    url = f"{CRAFTY_BASE_URL}{path}"
    resp = requests.delete(url, headers=HEADERS, verify=False)
    resp.raise_for_status()
    return resp.json()

10. Crafty System Info

    return crafty_get("/server/stats")

Get All Audit Log Entries

def get_audit_log():
    return crafty_get("/crafty/audit-log")

Error Handling

All functions can raise requests.HTTPError. Wrap calls for production use:

def safe_call(fn, *args, **kwargs):
    try:
        result = fn(*args, **kwargs)
        if result.get("status") == "ok":
            return result.get("data")
        else:
            print(f"Crafty API error: {result.get('error')} — {result.get('data')}")
            return None
    except requests.exceptions.ConnectionError:
        print(f"❌ Cannot connect to Crafty at {CRAFTY_BASE_URL}. Check HOST and PORT.")
    except requests.exceptions.HTTPError as e:
        print(f"❌ HTTP {e.response.status_code}: {e.response.text}")
    except Exception as e:
        print(f"❌ Unexpected error: {e}")
    return None

Common Patterns

Full Server Status Dashboard

def dashboard():
    servers = crafty_get("/servers").get("data", [])
    print(f"{'Name':\x3C25} {'Status':\x3C10} {'Players':\x3C12} {'CPU':\x3C8} {'RAM'}")
    print("-" * 70)
    for s in servers:
        sid = s["server_id"]
        stats = get_server_stats(sid).get("data", {})
        status  = "Online " if stats.get("running") else "Offline"
        players = f"{stats.get('online_players',0)}/{stats.get('max_players',0)}"
        cpu     = f"{stats.get('cpu', 0):.1f}%"
        ram     = f"{stats.get('mem', 0):.0f}MB"
        print(f"{s['server_name']:\x3C25} {status:\x3C10} {players:\x3C12} {cpu:\x3C8} {ram}")

Restart All Running Servers

def restart_all():
    servers = crafty_get("/servers").get("data", [])
    for s in servers:
        if s.get("running"):
            print(f"Restarting {s['server_name']}...")
            restart_server(s["server_id"])

Edit server.properties Value

def set_property(server_id: str, key: str, value: str):
    """
    Read server.properties, change one key, write it back.
    Example: set_property(sid, "max-players", "50")
    """
    result = read_file(server_id, "server.properties")
    content = result.get("data", {}).get("content", "")
    lines = content.splitlines()
    new_lines = []
    found = False
    for line in lines:
        if line.startswith(f"{key}="):
            new_lines.append(f"{key}={value}")
            found = True
        else:
            new_lines.append(line)
    if not found:
        new_lines.append(f"{key}={value}")
    write_file(server_id, "server.properties", "\
".join(new_lines))
    print(f"✅ Set {key}={value}")

API Response Structure

Every Crafty API response follows this envelope:

{
  "status": "ok",       // "ok" or "error"
  "data": { ... },      // payload (dict, list, or string)
  "error": null         // error message if status is "error"
}

Always check response["status"] == "ok" before using response["data"].

Notes

• SSL: Crafty uses a self-signed certificate by default. The helpers above pass verify=False. In production, provide your real cert path: verify="/path/to/cert.pem".
• API version: This skill targets Crafty Controller v4 (/api/v2 routes). Crafty 3 uses a different API.
• Permissions: Your API key inherits the permissions of the user it belongs to. For full access, generate the key from a superuser account.
• Rate limiting: Crafty does not enforce rate limiting by default, but avoid hammering the stats endpoint — poll at most once per 5 seconds.
