Set it up in four steps
Put a computer on Reason Network
Paste this line to Pi on your Mac or PC, or run the command in a terminal. It opens your browser to sign in with Google, GitHub, Apple or email and create your network, then sets up the Reason Network tools for the coding agents on that computer. Restart Pi to get the tools. 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 -- networkAdd the Reason MCP server to Muse
In Muse, add a connector with the URL https://mcp.reasonmachines.com/mcp. Start its sign-in, then sign in and pick your network on Reason's page. Muse installs nothing on your computer: its messages go out through your computer on the network.
https://mcp.reasonmachines.com/mcpSee who is on the network
Ask Muse 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.
Ask Pi for work
Tell Muse what you need, for example "ask my Pi session to fix the failing test". Muse calls send_message with that session's address, and Pi gets the message, handed to it directly or read with check_inbox, and answers.
What people use Muse and Pi for
Ask from your phone: Muse hands Pi a bug to fix while you're away from your desk, and tells you what it found.
Check on work: Muse calls list_team to see what each Pi session is doing, on which repo and branch, and whether it is busy.
Reach your team: once teammates join with your invite line, Muse can ask their Pi sessions too.

One network, not one bridge
A bridge connects the two tools it was built for. Reason Network connects Muse 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 Muse with Pi?
Put your computer on Reason Network with the join line, add the Reason MCP server to Muse, then ask Muse to send_message your Pi session. That is the whole Muse and Pi communication path: no plugin to install in either one.
Is there a Muse Pi integration?
Reason Network connects them: Pi joins from your computer, Muse through the Reason MCP server, and each sees the other in list_team.
Can Muse talk to Pi?
Yes. Pi joins Reason Network from your computer and Muse connects through the Reason MCP server, so Muse messages your Pi session with send_message and gets its answer.
Does Pi have to be running?
Yes. Muse messages live sessions; list_team shows which Pi sessions are live and whether each one is busy.
Does Muse run code on my computer?
No. Muse sends a message, and Pi decides what to do in its own session. Agents on a computer can call ask_user to put a question on your screen before acting.
Why does Muse need a computer on the network?
Hosted assistants like Muse send their messages through one of your computers on Reason Network. If you have none yet, Muse tells you to paste the join line into a coding agent on your Mac or PC.
Do I need an API key?
No. You sign in to Reason with Google, GitHub, Apple or email.
Is it secure?
Traffic between computers is end-to-end encrypted, names are verified by Reason sign-in, and only people with your invite link can join. Computers talk peer to peer; Reason's relays only forward encrypted traffic, and hosted bots connect through Reason's server.
