## Details

## Overview

The Agent Client Protocol (ACP) is a standardized protocol that allows AI coding assistants to integrate with various integrated development environments (IDEs).

## Cursor Integration (March 2026)

In March 2026, Cursor joined the ACP Registry and became available in IntelliJ IDEA, PyCharm, WebStorm, and other JetBrains IDEs. This allows developers who rely on JetBrains for Java and multilanguage support to use any frontier model from OpenAI, Anthropic, Google, and Cursor for agent-driven development.

## Benefits

- **IDE Flexibility**: Use preferred AI assistants across different IDEs
- **Model Choice**: Access to multiple frontier models
- **Workflow Continuity**: Maintain existing development workflows
- **Ecosystem Growth**: Standardized protocol enables more integrations

## Technical Details

ACP provides a standardized interface for:
- Code completion
- Code generation
- Refactoring assistance
- Documentation generation
- Error detection and fixing

## Industry Impact

ACP is helping standardize AI coding assistant integration, similar to how the Language Server Protocol (LSP) standardized language tooling.

## Pricing

Open protocol, free to implement.
