Adds a built-in mcp extension that reads mcp.json (agent dir, and .pi/mcp.json for trusted projects) in the common mcpServers format, connects stdio and streamable HTTP servers at session start, and registers their tools as mcp__<server>__<tool>. Calls go through the regular tool pipeline, so hooks and permission extensions apply. /mcp shows server status. By default a server's tools are codemode-only: the new nestedOnly tool flag keeps them executable for other tools but out of the model's tool declarations, and pi activates the codemode tool for them. "exposure": "direct" declares them to the model as well. structuredContent from tools with an outputSchema reaches codemode scripts as data. |

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
