# Pi ACP — AI Coding Tool Review & Pricing

> Pi ACP is an adapter that bridges the Agent Client Protocol with the pi coding agent. It enables the pi agent to run within ACP-compatible editors like Zed by managing session lifecycles, mapping data between protocols, and enabling features like slash commands.

## Key features

- ACP JSON-RPC 2.0 interface for pi coding agent
- Real-time streaming of assistant output and tool call updates
- Support for file-based, built-in, and skill slash commands
- Session persistence mapping between ACP and pi session files
- Terminal-based authentication flow for provider setup

## Pricing

**Model**: Open Source

## Who it is for

- **Best for**: Developers using the Zed editor who want to integrate the pi coding agent into their IDE workflow while retaining access to pi-specific features.
- **Not ideal for**: Users requiring ACP filesystem (fs/*) or terminal delegation, as pi reads/writes and executes locally without those specific delegations.

## Verdict

An essential, high-utility bridge for pi users, offering a polished way to manage agents within Zed, though it remains an MVP-style tool that may see minor breaking changes.

## Recent updates

Recent updates include improved session restoration, support for realized file mutation diffs, reporting of token usage and cost via usage_update notifications, and standardizing model configuration options.
