Discover, shortlist, compare, cost-model, and live-test 300+ AI models from your editor. This MCP server enables per-editor install configs and integrates with popular editors to streamline model evaluation and testing.

🛠️ Key Features

Discover and shortlist 300+ AI models from the editor environment
Compare models side-by-side and estimate costs with a built-in cost-model
Live-test models directly from your editor
Per-editor install configs for Cursor, VS Code, Claude Code, Codex
OpenRouter API key support for secure access

🚀 Use Cases

Rapid model scouting and evaluation within code editors
Side-by-side model comparison for feature and cost analysis
In-editor live-testing to validate model behavior before deployment
Config-driven MCP client setup for streamlined workflows

⚡ Developer Benefits

Lightweight MCP client integration via npm/npx
Generic MCP client config example with JSON snippet
Reusable per-editor install configurations
Clear README guidance for installation and usage

⚠️ Limitations

OpenRouter API key required for access
Live-testing relies on editor integration and per-editor configs
Documentation excerpt limited to initial readme content provided

Install

bash

npx -y @index9/mcp@latest

Generic MCP client config:

json

{
  "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.

Tools

list_facets: List available providers, capabilities, modalities, and tokenizers

find_models: Search AI models by semantic query or filters

get_models: Fetch full model metadata for up to 100 IDs or aliases

compare_models: Diff 2-10 models across pricing, context, capabilities, and tokenizer

test_model: 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)
