@index9/mcp

Give your AI assistant up-to-date model knowledge. 1000+ models with real-time pricing, context windows, and capabilities. Latest data, instant responses, zero cost.

Without Index9 MCP

LLMs rely on outdated training data about AI models:

• "Use GPT-4 for complex reasoning" (missing GPT-5.1, Claude Opus 4.5, and latest models)
• "This fits in GPT-3.5's 4K context" (current models have 128K-2M+ context windows)
• Generic advice without real pricing or capability comparisons
• No awareness of cutting-edge models released this month

With Index9 MCP

Your AI assistant has real-time access to the latest models and provides specific, data-driven recommendations:

• "Use GPT-5.1 - 400K context, $1.25/million input, latest frontier-grade reasoning with adaptive computation"
• "For massive documents, try Grok 4.1 Fast with 2M context at $0.2/million input tokens"
• "Vision + reasoning needed? Use Claude Opus 4.5 at $5/million - multimodal with 200K context"
• "Budget option: Arcee Trinity Mini at $0.04/million for text-only tasks"
• Compare the latest models side-by-side with current pricing, test live performance, and get cutting-edge recommendations

• This section was written using Index9 MCP data - the AI assistant knew about Arcee Trinity Mini before it was cool!*
