# Local MCP Server Configuration
MCP_SERVER_PORT=3000
MCP_SERVER_HOST=localhost
# MCP_AUTH_TOKEN=optional-for-local-development
# =========================
# SIMPLE HTTP MODE
# =========================
# Used for private single-user deployments
# Server mode: stdio (local) or http (remote)

# HTTP Server Configuration (only used when MCP_MODE=http)
PORT=3001
HOST=0.0.0.0
# Base URL Configuration (optional)
# Set this when running behind a proxy or when the server is accessed via a different URL
# than what it binds to. If not set, URLs will be auto-detected from proxy headers (if TRUST_PROXY is set)
# or constructed from HOST and PORT.
# Examples:
# BASE_URL=https://n8n-mcp.example.com
# BASE_URL=https://your-domain.com:8443
# PUBLIC_URL=https://n8n-mcp.mydomain.com (alternative to BASE_URL)
# Authentication token for HTTP mode (REQUIRED)
# Generate with: openssl rand -base64 32
AUTH_TOKEN=your-secure-token-here
# CORS origin for HTTP mode (optional)
# Default: * (allow all origins)
# For production, set to your specific domain
# CORS_ORIGIN=https://your-client-domain.com
# Trust proxy configuration for correct IP logging (0=disabled, 1=trust first proxy)
# Set to 1 when running behind a reverse proxy (Nginx, Traefik, etc.)
# Set to the number of proxy hops if behind multiple proxies
# Default: 0 (disabled)
# TRUST_PROXY=0

# N8N API CONFIGURATION
# =========================
# Optional: Enable n8n management tools by providing API credentials
# These tools allow creating, updating, and executing workflows
# n8n instance API URL (without /api/v1 suffix)
# Example: https://your-n8n-instance.com
# N8N_API_URL=
# n8n API Key (get from Settings > API in your n8n instance)
# N8N_API_KEY=
# n8n API request timeout in milliseconds (default: 30000)
# N8N_API_TIMEOUT=30000
# Maximum number of API request retries (default: 3)
# N8N_API_MAX_RETRIES=3
