kie-mcp

A comprehensive Model Context Protocol server for the kie.ai generation API. Gives Claude (and any MCP client) access to 47+ image models, 80+ video models, and 20+ audio tools with deep model intelligence built in.

Why this exists

Most MCPs are thin API wrappers. This one is different:

Deep research embedded — Every major model has a research field with verdicts, prompt techniques, weaknesses, cost-efficiency analysis, and competitor comparisons. Researched by Averiguare, our model intelligence agent.
Cost-aware — Every model has pricing in credits and USD. The MCP tells you the cheapest option for your use case.
Smart filtering — list_models filter="lip sync" or filter="architecture" or filter="cheapest video" — searches across capability tags, descriptions, AND research fields.
Dual-mode transport — stdio for local Claude Code, HTTP Streamable for remote Cowork/cloud usage.

What you can do with it

Just ask Claude things like:

"Generate a brand presentation board for a perfume launch" — picks GPT Image 2 (best for text-heavy layouts)
"Make a 10s video of fruit scarecrows defending against crows, Pixar style" — recommends Veo 3.1 or Wan 2.7
"Generate music for a fantasy adventure game" — Suno V5
"Lip-sync this audio to my character image" — Kling AI Avatar or Infinitalk
"Upscale this video to 4K" — Veo 4K upscale or Topaz
"Replace the wall color in this room photo" — Flux Kontext Pro (best for surgical edits)

Installation

Prerequisites

Node.js 18+
A kie.ai API key from kie.ai/api-key

Setup

bash

git clone https://github.com/YOUR_USERNAME/kie-mcp.git
cd kie-mcp
npm install

Run as stdio MCP (Claude Code, Claude Desktop)

Add to your Claude config (~/.claude.json for Claude Code, or your MCP client's equivalent):

json

{
  "mcpServers": {
    "kie-art": {
      "command": "node",
      "args": ["/absolute/path/to/kie-mcp/server.mjs"],
      "env": {
        "KIE_API_KEY": "your-kie-ai-api-key",
        "KIE_PROJECT_ROOT": "/optional/path/for/outputs"
      }
    }
  }
}

Or use the Claude Code CLI:

bash

claude mcp add -s user kie-art /usr/bin/env -- KIE_API_KEY=your-key node /path/to/server.mjs

Run as HTTP MCP (Cowork, remote clients)

bash

KIE_API_KEY=your-key node server.mjs --http --port=3100

Then expose via ngrok / Cloudflare Tunnel / VPS deployment:

bash

ngrok http 3100

Configure your MCP client to use the resulting URL:

json

{
  "mcpServers": {
    "kie-art": {
      "type": "http",
      "url": "https://your-tunnel.ngrok-free.dev/mcp"
    }
  }
}

Environment variables

Variable	Required	Purpose
`KIE_API_KEY`	yes	Your kie.ai API key
`KIE_PROJECT_ROOT`	no	Where generated files are saved (default: current working dir). Files go to `$KIE_PROJECT_ROOT/kie/assets/raw/`
`KIE_MCP_PORT`	no	Port for HTTP mode (default: 3100)
`KIE_CALLBACK_URL`	no	Callback URL sent with Suno generation requests (kie.ai requires the field; results are fetched by polling regardless). Defaults to an inert placeholder — set this only if you want to receive the callbacks yourself

Smart model recommendations

Try these queries in any MCP client:

code

list_models filter="reasoning"          # GPT-4o, Nano Banana, GPT Image 2
list_models filter="lip-sync"           # OmniHuman 1.5, Volcengine, Kling Avatar, HappyHorse 1.1
list_models filter="multi-shot"         # Kling 3.0/Turbo
list_models filter="cheapest video"     # Grok Imagine 1.5, Wan Flash
list_models filter="alibaba"            # HappyHorse 1.0/1.1 family
list_models filter="best visual quality" # Veo Quality, Seedance 2.0
list_models filter="text rendering"     # Ideogram v3, GPT Image 2
list_models filter="character"          # Ideogram Character, Kling AI Avatar

Architecture

code

server.mjs                      # The whole server (~4000 lines)
├── PRICING                     # Credit cost per model
├── MODEL_REGISTRY              # Image models (47+)
├── VIDEO_MODEL_REGISTRY        # Video models (80+)
├── AUDIO_TOOLS_REGISTRY        # Audio tool metadata
├── createMcpServer()           # Factory for stdio + HTTP modes
└── Tool handlers               # generate_*, list_*, etc.

Each model entry has:

name, description, capabilities (tags), pricing (credits)
aspectRatios, options (with types and defaults)
buildBody / buildInput (request builders)
research (Averiguare verdicts, prompt techniques, weaknesses, comparisons, sources)
