Overview

What is Atomic Chat?

Atomic Chat is a free, open-source desktop and mobile app for running local LLMs and connecting MCP servers directly to your models. It acts as an MCP host: add a server once and its tools are available in every chat — local or cloud.

How to use MCP with Atomic Chat

  • Download from https://atomic.chat (macOS, Windows, Linux, iOS, Android)

  • Open Settings → MCP Servers → Add

  • Paste any MCP server config (name, transport: STDIO / HTTP / SSE, command or URL)

  • Start chatting — the model picks and calls tools automatically

Works with any server from mcp.so and the official MCP registry.

Key features

  • MCP host - connect multiple MCP servers; in app log viewer for tool calls
  • Local models - Llama, Qwen, DeepSeek, Gemma, Mistral and 1000+ more from Hugging Face
  • Cloud providers - OpenAI, Anthropic, Mistral, Groq, MiniMax (bring your own key)
  • OpenAI-compatible API - http://localhost:1337/v1 for agents, CLIs, and IDE plugins
  • Privacy - with local models, prompts and tool calls stay on your machine
  • Built for agents - integrates with Kilo Code, OpenCode, Goose, and others.

Use cases

  1. Connect Notion, GitHub, Google Drive or web search to a local model
  2. Run agents and coding tools on your own hardware via the local API
  3. Mix local inference with cloud models without reconfiguring MCP servers

FAQ

Which MCP transports are supported?
STDIO, HTTP, and SSE.

Does my data go through Anthropic or OpenAI?
With a local model, tool calls go from your machine to the MCP server you connected — not through an AI provider.

Is it free?
Yes. Open-source under Apache 2.0.
