Cobolt

What is Cobolt?

Cobolt is a cross-platform desktop application that runs locally on your device, using local AI models via Ollama to provide answers and perform actions on your data without sending it to external servers. It supports the Model Context Protocol (MCP) to connect to tools and data sources.

How to use Cobolt?

Install the appropriate binary for your operating system (macOS, Windows, or Linux) from the releases page. Ensure required system dependencies are installed (Homebrew on macOS, Winget on Windows, or run the linux_deps.sh script on Linux). Then download and configure Ollama models (default is llama3.2:3b for inference, nomic-embed-text for embedding) and add MCP integrations through the app’s JSON configuration file, using the same format as Claude Desktop.
