What its tools let an agent do: 5 read

Install Index9 in Claude Code, Cursor or VS Code

Runs npx -y @index9/mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add mcp -- npx -y @index9/mcp
Add to Cursor

What the publisher says

From the Index9 repository's README, as published. We do not edit it. Read it on GitHub

@index9/mcp

Discover, shortlist, compare, cost-model, and live-test 300+ AI models from your editor

Per-editor install configs (Cursor, VS Code, Claude Code, Codex): https://index9.dev/#install

Install

npx -y @index9/mcp@latest

Generic MCP client config:

{
  "mcpServers": {
    "index9": {
      "command": "npx",
      "args": ["-y", "@index9/mcp@latest"],
      "env": {
        "OPENROUTER_API_KEY": "sk-or-..."
      }
    }
  }
}

Claude Code one-liner: claude mcp add --transport stdio index9 -- npx -y @index9/mcp.

OpenRouter API key

Required for live testmodel calls. Set OPENROUTERAPI_KEY in your MCP client config. dryRun=true works without it.

Tools

  • listfacets**: List available providers, capabilities, modalities, and tokenizers
  • findmodels**: Search AI models by semantic query or filters
  • getmodels**: Fetch full model metadata for up to 100 IDs or aliases
  • comparemodels**: Diff 2-10 models across pricing, context, capabilities, and tokenizer
  • testmodel**: Run live inference or dry-run cost estimates on 1-10 models (requires OpenRouter API key)

Response metadata

All tool responses include an _index9 object with:

  • apiBaseUrl: API base URL used for the request

Error responses also include:

  • status: upstream HTTP status code
  • _index9.retryAfterSeconds: present when Retry-After is returned
  • _index9.rateLimit: present when rate-limit headers are returned (x-ratelimit-limit, x-ratelimit-remaining, x-ratelimit-reset)

Nothing above is checked by us. What we check is on the safety report.
