FAQ

How does Jan handle the integration of external tools and agentic capabilities into its local AI models?

Jan allows users to integrate Model Context Protocol (MCP) servers to provide agentic capabilities to AI models. This system enables the creation of custom AI assistants that can perform specific tasks or access external data sources while maintaining local control over the execution environment (verified: 2026-01-29).

What options are available for users who want to use Jan as a backend for other applications?

Jan includes a local API server that exposes an OpenAI-compatible API directly from the user's machine. This allows developers to point other applications or scripts to Jan's local endpoint to utilize open-source models without relying on external cloud infrastructure (verified: 2026-01-29).

Can users access proprietary cloud models through the Jan interface or is it limited to local models?

While Jan focuses on local execution, it also supports remote cloud models. Users can connect to external providers like Anthropic by entering their own API keys, allowing them to switch between local open-source models and remote proprietary ones within the same interface (verified: 2026-01-29).
