Quick Start

Try the Public API

# List latest models
curl "https://modelsplus.quivr.tech/v1/models?limit=5"

# Find reasoning-capable models
curl "https://modelsplus.quivr.tech/v1/models?reasoning=true"

# Get specific model details
curl "https://modelsplus.quivr.tech/v1/models/openai:gpt-4o"

Local Development

# Install dependencies
bun install

# Start development server
bun run dev

# Build for production
bun run build

Installation

📋 Requirements

• Bun 1.2.21 - Runtime and package manager

• Node.js types - For tooling compatibility (bundled via SST)

Quick Install

# Install dependencies
bun install

# Generate JSON assets from vendor data
cd packages/api && bun run generate && bun run build

Development

Useful Scripts

• bun run build — Build all workspaces

• bun run dev — SST Dev with Cloudflare Worker locally

• bun run dev:api — Direct Worker dev for API only

• bun run deploy — Deploy via SST to Cloudflare Workers

• bun run sync:upstream — Sync vendor subtree

Development Setup

1. Generate JSON assets from vendor TOML files:

   cd packages/api
   bun run generate
   bun run build

2. Run development servers:

   # SST Dev (recommended)
   bun run dev
   
   # Direct Worker dev
   cd packages/api && bun run dev

Note: SST config (sst.config.ts) auto-builds @modelsplus/api and exposes the Worker URL.

Code Examples

JavaScript/TypeScript:

// Search models
const models = await fetch('https://modelsplus.quivr.tech/v1/models?reasoning=true&limit=5')
  .then(res => res.json());

// Get specific model
const model = await fetch('https://modelsplus.quivr.tech/v1/models/openai:gpt-4o')
  .then(res => res.json());

Python:

import requests

# Find vision-capable models
response = requests.get('https://modelsplus.quivr.tech/v1/models',
                       params={'modalities': 'image', 'limit': 5})
models = response.json()

MCP Integration

Models PLUS provides native Model Context Protocol (MCP) support for seamless integration with AI assistants.

Available Tools

• search_models - Advanced search and filtering for AI models

• get_model - Detailed information about specific models

• search_providers - Search and filter AI providers

• get_provider - Detailed provider information

Quick Setup

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "models-plus": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/sdk", "server", "https://modelsplus.quivr.tech/mcp"]
    }
  }
}

Cursor

Configure MCP server with URL: https://modelsplus.quivr.tech/mcp

Other MCP Clients

For any MCP-compatible client, use: https://modelsplus.quivr.tech/mcp

Usage Examples

Once integrated, use natural language:

• "Find all GPT-4 models from OpenAI"

• "Show me reasoning-capable models under $1 per million tokens"

• "What are the specs for Claude 3 Opus?"

• "Which providers support tool calling?"

Direct HTTP API

# Discover capabilities
curl "https://modelsplus.quivr.tech/mcp"

# List available tools
curl -s "https://modelsplus.quivr.tech/mcp" \
  -X POST \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Data Source

Model and provider metadata sourced from models.dev TOML files. The build process (packages/api/src/generate.ts) converts these into optimized JSON artifacts for the API and MCP handlers.

Deployment

Deploys via SST to Cloudflare Workers:

bun run deploy

SST config creates a sst.cloudflare.Worker with global edge deployment.
