Armin Ronacher a6bc4036d7 feat(coding-agent): let extensions register MCP servers
pi.registerMcpServer(name, config) adds a server for the session with the mcp.json config shape; pi.unregisterMcpServer() removes it and pi.getMcpServers() lists registrations. Servers registered while loading connect on session_start, later ones right away. A server in mcp.json with the same name takes precedence and /mcp shows the override. Changes to registered servers in /mcp apply to the session only.

The mcp_servers_change event lets any MCP extension connect registered servers; when none handles it, registrations are reported as extension errors.

Pi

Pi is a minimal, extensible AI agent for the terminal. Adapt Pi to your workflow, not the other way around.

Ask Pi to create the prompt templates, skills, extensions, and themes you need, or install a Pi package. Use Pi directly, automate it in print, JSON, or RPC mode, or build applications with the TypeScript SDK.

Getting started

Install the command-line interface with npm:

npm install -g --ignore-scripts @earendil-works/pi-coding-agent

This requires Node.js 22.19 or newer. Pi does not require dependency lifecycle scripts for a normal npm installation.

On macOS or Linux, you can instead use the installer:

curl -fsSL https://pi.dev/install.sh | sh

Start Pi in the directory where you want it to work:

cd /path/to/project
pi

For a built-in AI provider, run /login inside Pi to connect a subscription or API key. Then give Pi a task.

See the documentation for full setup and usage instructions.

Development

Clone the repository, install its dependencies, and run Pi from source:

git clone https://github.com/earendil-works/pi
cd pi
npm install --ignore-scripts
./pi-test.sh

pi-test.sh can be called from any directory and preserves the caller's working directory.

Before submitting changes, run:

npm run check
./test.sh
