What is the Index9 MCP Server?

The Index9 MCP server is a tool specifically designed for AI assistants. It connects to the OpenRouter platform and provides real-time information on over 300 AI models. When an AI assistant needs to know the pricing, capability limits, or latest features of different models, Index9 is the most accurate source of information.

How to use the Index9 MCP Server?

Simply add a simple configuration to your AI client (such as Cursor, VS Code, Claude Desktop, etc.), and Index9 will be automatically integrated into your AI assistant. After that, you can directly ask the AI assistant for information about the models, and it will obtain the latest data through Index9 to answer you.

Use Cases

When you need to select the most suitable AI model for a specific task; when you want to compare the costs and performance of different models; when you need to know the latest capability limits of a certain model; when you want to test the actual performance of different models.

Main Features

Model Search
Search for over 300 AI models by natural language or filtering criteria, supporting filtering by price, context length, capabilities, etc.
Detailed Specification View
Get the complete technical specifications of any model, including real-time pricing, context limits, API rate limits, and special capabilities.
Model Testing
Send the same request to multiple models and compare their output quality, response speed, and actual costs.
Real-time Data
All information is directly obtained from the OpenRouter API, ensuring that the pricing and specification information is up-to-date.
Advantages
Solve the problem of outdated knowledge in AI assistants - AI models are updated frequently, and Index9 provides real-time information.
One-stop comparison - No need to switch between multiple websites. Directly compare all mainstream models.
Cost transparency - Clear pricing information helps you make cost-effective decisions.
Easy to integrate - Can be used in multiple AI clients with simple configuration.
No need to memorize - The AI assistant automatically uses the latest data, and you don't need to manually search for information.
Limitations
Requires an OpenRouter account - The testing function requires an API key.
Depends on the OpenRouter platform - Model availability is affected by OpenRouter's support.
Testing incurs costs - Actual model testing consumes OpenRouter credits.
Requires client support - Must use an AI client that supports the MCP protocol.

How to Use

Select Your AI Client
Index9 supports multiple AI clients, including Cursor, VS Code, Claude Desktop, etc. Select the client you are using.
Add MCP Server Configuration
