HTTP API agent for remote model management

XM Agent

HTTP API agent for remote model management. Runs on RunPod or Linux servers and exposes endpoints for model listing, hashing, downloading, and CivitAI metadata lookup.

Installation

# Using uv
uv pip install xm-agent

# Or from git
pip install git+https://github.com/user/xm-agent.git

# Or install locally for development
cd xm-agent
uv sync --dev

Configuration via environment variables:

Variable	Default	Description
XM_AGENT_HOST	0.0.0.0	Server bind address
XM_AGENT_PORT	8765	Server port
XM_AGENT_MODELS_PATH	/workspace/ComfyUI/models	Base path for model directories
CIVITAI_API_KEY	-	CivitAI API key for gated models

RunPod

On RunPod, the agent auto-detects the environment via RUNPOD_POD_ID and prints the proxy URL on startup:

XM Agent v0.1.0 starting...
Listening on 0.0.0.0:8765
Models path: /workspace/ComfyUI/models
RunPod detected: abc123xyz
Proxy URL: https://abc123xyz-8765.proxy.runpod.net

Security

• Only downloads from allowed domains (CivitAI, HuggingFace)
• Path traversal protection for model file operations
• No authentication by default (assumes trusted network/RunPod proxy)
