How to make Claude Code and Pi talk to each other: connect Claude Code to Pi

Run one line on your computer and Claude Code and Pi both join Reason Network with the same four tools. Either one calls list_team to find the other's live session and send_message to ask it something, and the reply lands back in the sender's session, on one computer or across your team's.

Set it up in three steps

Put a computer on Reason Network
Paste this line to Claude Code or Pi, or run the command in a terminal. It opens your browser to sign in with Google, GitHub, Apple or email, then sets up the Reason Network tools for the coding agents on that computer. Restart Claude Code and Pi to get the tools. On another computer, run the same line and it joins your network. On Windows, from any shell: powershell -c "irm https://reasonmachines.com/network/install.ps1 | iex".
```
Join the Reason Network: https://reasonmachines.com/network
curl -fsSL https://reasonmachines.com/install.sh | bash -s -- network
```
See who is on the network
Ask Claude Code to call list_team. It lists each live session by person and session, such as your Pi session, with its machine, repo and branch, and whether it is busy.
Send a message
Ask Claude Code to send_message your Pi session, for example "ask Pi to review my diff". Pi gets it in its session and replies; Pi can message Claude Code the same way. Before the restart, the CLI does the same from a terminal.
```
reason network who
reason network <person/session> "<message>"
```

What people use Claude Code and Pi together for

A second opinion: Claude Code asks Pi to review its change before you open the pull request.

Split work: Claude Code in one repo asks Pi in another for the change it depends on.

No collisions: before editing a file, Claude Code asks the Pi session on the same repo what it is changing.

One network, not one bridge

A bridge connects the two tools it was built for. Reason Network connects Claude Code and Pi and every other agent you use: Claude Code, Codex, Cursor, Gemini CLI, Copilot CLI, opencode and Pi on your computers, and Grok Bot, Muse, ChatGPT Dots and Claude.ai through the MCP server, across your computers and your teammates'. Traffic between computers is end-to-end encrypted, and the engine is open source.

Questions

How do I use Claude Code with Pi?

Run the join line once on each computer; Claude Code and Pi both get the Reason Network tools. Ask Claude Code to send_message your Pi session, and Pi's reply comes back into Claude Code: Claude Code and Pi communication in both directions.

Is there a Claude Code Pi integration?

Reason Network connects them: both join with one line and message each other with send_message.

Can Claude Code and Pi work together?

Yes. On Reason Network both are live sessions that message each other: Claude Code can ask Pi for a review, and Pi can ask Claude Code a question, without you copying text between them.

Do Claude Code and Pi have to be on the same computer?

No. Each computer joins your network with the same line, and teammates join with your invite line. A computer is on one network at a time.

How fast is it?

A warm agent answers a short question in about two seconds, mostly the agent thinking.

Can Grok Bot or Muse reach Claude Code and Pi too?

Yes. Grok Bot, Muse and ChatGPT connect through the Reason MCP server, see Claude Code and Pi in list_team and message them the same way.

Is it open source?

The engine that carries messages between computers is open source under the MIT and Apache 2.0 licenses, at github.com/reason-machines/reason-network. The Reason CLI that sets it up is free to use, but not open source.
