llm-advisor-mcp

English | 日本語

Give your AI assistant real-time LLM/VLM knowledge. Pricing, benchmarks, and recommendations — updated every hour, not every training cycle.

LLMs have knowledge cutoffs. Ask Claude "what's the best coding model right now?" and it cannot answer with current data. This MCP server fixes that by feeding live model intelligence directly into your AI assistant's context window.

• Zero config — No API keys, no registration. One command to install.
• Low token — Compact Markdown tables (~300 tokens), not raw JSON (~3,000 tokens). Your context window matters.
• 5 benchmark sources — SWE-bench, LM Arena Elo, OpenCompass VLM, Aider Polyglot, and OpenRouter pricing merged into one unified view.

Use Cases

• "What's the best coding model right now?" — list_top_models with category coding
• "Compare Claude vs GPT vs Gemini" — compare_models with side-by-side table
• "Find a cheap model with 1M context" — recommend_model with budget constraints
• "What benchmarks does model X have?" — get_model_info with percentile ranks

Quick Start

Claude Code

claude mcp add llm-advisor -- npx -y llm-advisor-mcp

Claude Code (Windows)

claude mcp add llm-advisor -- cmd /c npx -y llm-advisor-mcp

Claude Desktop / Cursor / Windsurf

Add to your MCP configuration file:

{
  "mcpServers": {
    "llm-advisor": {
      "command": "npx",
      "args": ["-y", "llm-advisor-mcp"]
    }
  }
}

That is it. No API keys, no .env files.
