## Install

```bash
# Homebrew
brew install portofcontext/tap/pctx

# cURL
curl --proto '=https' --tlsv1.2 -LsSf https://raw.githubusercontent.com/portofcontext/pctx/main/install.sh | sh

# npm
npm i -g @portofcontext/pctx
```

## Core Functionality

pctx can be run as a stateless HTTP server for Code Mode sessions or as a unified MCP server that exposes Code Mode functionality for registered upstream MCP servers.

```bash
# Start Code Mode for Python SDK
pctx start

# Start Code Mode as a unified MCP server
pctx mcp init
pctx mcp dev
```

## Python SDK

Use the Python SDK if building agents in Python and want to run Code Mode with custom tools and/or MCP servers. The Python SDK is an HTTP client to the `pctx` server.

```bash
pip install pctx-client
```

```python
from pctx_client import Pctx, tool
from age
