Roo Code

Roo Code supports OpenAI-compatible API profiles. Use ModRouter’s OpenAI-compatible endpoint.

Endpoint

https://api.modrouter.online/openai/v1

Set MODROUTER_BASE_URL to the ModRouter root URL reachable by Roo Code.

Open Roo Code settings.
Create or edit an OpenAI-compatible API profile.
Set Base URL to your ModRouter /openai/v1 endpoint.
Set API Key to a ModRouter virtual key, or a placeholder value if auth is disabled.
Set Model to a ModRouter model ID.

Examples:

openai/gpt-4o-mini
anthropic/claude-sonnet-4-5
gemini/gemini-2.5-pro

Roo Code can also connect to MCP servers. To expose ModRouter-managed tools, add:

https://api.modrouter.online/mcp

Use the same auth headers configured for your ModRouter MCP gateway.
