MCP Server Overview - MeiGen Docs

What is MCP?

Model Context Protocol (MCP) is an open standard that allows AI assistants to use external tools. When you install MeiGen as an MCP server, your AI assistant gains the ability to generate images and videos, search a curated 1,446-prompt gallery, and enhance prompts — all through natural language.

Providers

MeiGen supports three image generation backends — configure one or more.

MeiGen Cloud

Hosted multi-model API. 9 image and video models: GPT Image 2, Nanobanana Pro/2, Seedream, Midjourney V8.1, Flux 2 Klein, Seedance 2.0, Happyhorse 1.0, Veo 3.1. No GPU required — just an API key.

ComfyUI

Local GPU generation. Run any Stable Diffusion, SDXL, or Flux model on your own hardware. Full control over workflows and parameters.

Bring Your Own API

Any OpenAI-compatible API. Connect Together AI, Fireworks AI, DeepInfra, SiliconFlow, OpenAI, or your own endpoint.

Provider	Type	Cost	Best For
MeiGen Cloud	Hosted API	Credits (pricing)	Multi-model access, zero setup
ComfyUI	Local GPU	Free (your hardware)	Full control, custom workflows, privacy
Bring Your Own API	OpenAI-compatible	Varies by service	Existing API keys, any provider

Provider priority: When multiple providers are configured, MeiGen selects in this order: MeiGen Cloud → ComfyUI → OpenAI-compatible. You can override this per-request.

Supported Platforms

Claude Code

Install as a plugin from the marketplace — includes slash commands, smart agents, and automation hooks.

Cursor / VS Code / Windsurf / Roo Code

One-command setup via npx meigen init <host> — writes the right MCP config file for each editor.

OpenAI Codex CLI

Add the MCP server to ~/.codex/config.toml. Standard stdio MCP, no extra plumbing.

Hermes Agent

First-class MCP support — add to ~/.hermes/config.yaml with timeout: 600 for video generation.

OpenClaw

Install as a plugin from ClawHub — includes skills, commands, and MCP server.

Any MCP host

Standard stdio MCP — point any MCP-compatible host at npx -y meigen@latest.

Standalone CLI Mode

No MCP host? MeiGen also ships as a CLI for shell scripts and CI pipelines:

export MEIGEN_API_TOKEN=meigen_sk_...
npx meigen gen --prompt "a calico cat in a sunlit kitchen"
npx meigen gen -p "logo design" -m midjourney-v8.1 -r 1:1 --json

Use --json for machine-readable output, --no-wait to submit without polling, and --reference <path|url> to pass a reference image. Run npx meigen gen --help for the full flag list.
