Model Hub MCP Server

Provides unified access to model metadata from OpenAI, Anthropic, and Google via MCP client integration.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "akiojin-model-hub-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@akiojin/model-hub-mcp"
      ],
      "env": {
        "GOOGLE_API_KEY": "YOUR_GOOGLE_API_KEY",
        "OPENAI_API_KEY": "YOUR_OPENAI_API_KEY",
        "ANTHROPIC_API_KEY": "YOUR_ANTHROPIC_API_KEY"
      }
    }
  }
}

This MCP server fetches AI model information from OpenAI, Anthropic, and Google, and presents a unified way to list models and retrieve detailed model data from all configured providers. It helps you compare, combine, and access model metadata in a consistent interface from your MCP client.

How to use

You integrate this MCP server into your MCP client configuration to access model information from multiple providers. The server exposes endpoints to list models from a chosen provider, get detailed information about a specific model, and batch-fetch models from all configured providers. Use your MCP client to request data from the server, specifying the provider and model identifiers as needed.

Typical usage flows include: listing available models for a provider (openai, anthropic, or google), retrieving detailed model data by model_id, and performing a batch fetch to collect information from all configured providers in one call.

How to install

Prerequisites you need before installing:
- Node.js (16.x or newer) and npm
- Internet access to fetch packages from npm
- A MCP client environment that can connect to MCP servers

Step-by-step commands to use the MCP server with npm and npx:
1) Quick start with npx (no local install required):
`OPENAI_API_KEY=your_key npx @akiojin/model-hub-mcp

2) Global installation (optional):
`npm install -g @akiojin/model-hub-mcp

3) Local installation (recommended if you plan to modify or host locally):
`npm install @akiojin/model-hub-mcp

4) Build (for TypeScript sources, if you clone and run locally):
`npm run build

Configuration and runtime notes

Configure API keys in a single environment file so your MCP client can securely pass credentials to the server. You can leave keys blank for providers you do not plan to use.

Key environment variables shown in examples: - OPENAI_API_KEY - ANTHROPIC_API_KEY - GOOGLE_API_KEY

Example runtime usage with environment variables passed at startup:
`OPENAI_API_KEY=your_openai_api_key ANTHROPIC_API_KEY=your_anthropic_api_key GOOGLE_API_KEY=your_google_api_key npx @akiojin/model-hub-mcp

Notes and tips

This MCP server is designed to be consumed by your MCP client configuration. It is not intended to run standalone in production without a client context.
