Cline’s OpenAI Compatible provider accepts NagaAI’s base URL. Any chat model that supports tools can drive Cline’s agent. This provider sends only Chat Completions, and Cline has no Responses option for custom endpoints. The fields below follow the Cline docs.

​
Before you start

You need a NagaAI API key and Cline 4.1.13 or later in VS Code. Older versions could strip tools from requests to custom OpenAI-compatible models.

​
Connect Cline

1

Choose the provider

In the Cline settings, choose the OpenAI Compatible provider and fill in the fields.
2

Describe the model

Under Model Configuration, set the context window from limits.context_window of the model’s chat operation in /v1/models. Turn on image support if the model accepts images, and enter prices if you want Cline to show costs.
3

Check the connection

Send a short task. The request appears in Logs in your dashboard.

​
Use the Anthropic provider

Cline can also use its Anthropic provider with the custom base URL https://api.naga.ac. Prompt caching doesn’t work through NagaAI, so Claude models get no cache hits there. Roo Code was shut down on May 15, 2026, and its authors point to Cline.

​
Troubleshooting

​
401 invalid_api_key

Cline sent no key or a wrong one. Paste your NagaAI API key into the API Key field again. A provisioning key doesn’t work there.

​
The model ignores tools

You’re on a Cline version older than 4.1.13, which could strip tools from custom OpenAI-compatible requests. Update Cline.
