Tandem MCP: Run and Manage Claude Code Sessions from Claude.ai Chat
Tandem is an open-source MCP (Model Context Protocol) server that connects Claude.ai browser chat directly to local Claude Code CLI sessions. It eliminates the copy-paste cycle between brainstorming in chat and executing code on the terminal.
How It Works
Tandem operates as a bidirectional loop:
- You work in Claude.ai chat as usual — brainstorm, write specs, plan architecture.
- When ready, Tandem can start a new Claude Code session or resume an existing one on your local machine.
- Claude Code executes tasks and sends output back into the Claude.ai browser chat.
- Claude.ai can then respond with further instructions back down through the CLI, creating an autonomous loop.
The key insight: Claude.ai manages Claude Code, not you. You stay in the browser IDE for brainstorming and the actual work happens automatically on your machine.
Installation & Usage
Tandem is fully open source and available on GitHub. To get started:
git clone https://github.com/Maxmedawar/tandem
cd tandem
# Follow the README for MCP configuration
# Add the MCP server to your Claude.ai settings
Once configured, Tandem registers as an MCP tool within Claude.ai. You can invoke it with natural language prompts like Run a Claude Code session to implement the spec above.
Why It Matters
No more manual context transfer. No switching windows to start a session. No copy-paste errors. The chat remains your single point of control while Claude Code does the heavy lifting on your local environment — file system, shell access, tools.
This is especially useful for developers who want to:
- Iterate on specs and then execute without leaving the chat.
- Resume interrupted work directly from a browser session.
- Chain brainstorming and coding in an automated loop.
