Model Configuration

Adding Models

Models are configured in config/config.json under the models array. Each model needs:

json

{
  "name": "model-id",
  "displayName": "Friendly Name",
  "description": "Short description shown in model picker",
  "provider": "gemini|openai|openrouter",
  "supportsTools": true,
  "multimodal": false,
  "parameters": { "temperature": 0.7 }
}

Providers

Provider	Model Name Pattern	API Key Env Var	Secret Name
`gemini`	`gemini-*`	`GOOGLE_API_KEY`	`google-api-key`
`openai`	`gpt-`, `o3-`, `o4-*`	`OPENAI_API_KEY`	`openai-api-key`
`openrouter`	`vendor/model-name`	`OPENROUTER_API_KEY`	`openrouter-api-key`

The MCP Bridge auto-detects the provider from the model name:

Starts with gemini- → Google Gemini API
Contains / → OpenRouter
Everything else → OpenAI
