+# ACP (Agent Client Protocol) Examples
+
+This directory contains examples for using PraisonAI with the Agent Client Protocol (ACP).
+
+## What is ACP?
+
+The Agent Client Protocol (ACP) is a standardized JSON-RPC 2.0 protocol that allows code editors and IDEs to communicate with AI coding agents. It enables seamless integration between PraisonAI and editors like:
+
+- **Zed**
+- **JetBrains IDEs** (IntelliJ, PyCharm, WebStorm, etc.)
+- **VSCode** (via extensions)
+- **Toad**
+
+## Quick Start
+
+### CLI Usage
+
+```bash
+# Start ACP server with defaults
+praisonai acp
+
+# Enable debug logging
+praisonai acp --debug
+
+# Allow file writes
+praisonai acp --allow-write
+
+# Use a specific model
+praisonai acp -m gpt-4o
+
+# Resume last session
+praisonai acp --resume --last
+```
+
+### Python API
+
+```python
+from praisonai.acp import serve
+
+serve(
+    workspace=".",
+    debug=True,
+    allow_write=True,
+)
+```
+
+## Editor Configuration
+
+### Zed
+
+Add to `~/.config/zed/settings.json`:
+
+```json
+{
+  "agent_servers": {
+    "PraisonAI": {
+      "command": "praisonai",
+      "args": ["acp"],
+      "env": {}
+    }
+  }
+}
+```
+
+### JetBrains
+
+Add to `~/.jetbrains/acp.json`:
+
+```json
+{
+  "agent_servers": {
+    "PraisonAI": {
+      "command": "praisonai",
+      "args": ["acp"],
+      "env": {}
+    }
+  }
+}
+```
+
+### Toad
+
+```bash
+toad acp "praisonai acp"
+```
+
+## Examples
+
+- `basic_acp_server.py` - Simple ACP server with default settings
+- `custom_agent_acp.py` - ACP server with a custom agent
+
+## CLI Options
+
+| Option | Description |
+|--------|-------------|
+| `-w, --workspace` | Workspace root directory |
+| `-a, --agent` | Agent name or config file |
+| `-m, --model` | LLM model to use |
+| `-r, --resume` | Resume session by ID |
+| `--last` | Resume the last session |
+| `--approve` | Approval mode: manual, auto, scoped |
+| `--read-only` | Read-only mode (default) |
+| `--allow-write` | Allow file writes |
+| `--allow-shell` | Allow shell commands |
+| `--debug` | Enable debug logging |
+
+## Installation
+
+```bash
+pip install praisonai[acp]
+```
+
+## Protocol Details
+
+ACP uses JSON-RPC 2.0 over stdio:
+- **stdin**: Receives JSON-RPC requests from the client
+- **stdout**: Sends JSON-RPC responses to the client
+- **stderr**: Debug/log output (never pollutes stdout)
+
+### Supported Methods
+
+**Agent Methods (client → agent):**
+- `initialize` - Negotiate protocol version and capabilities
+- `authenticate` - Optional authentication
+- `session/new` - Create a new session
+- `session/load` - Load an existing session
+- `session/prompt` - Send user message
+- `session/cancel` - Cancel ongoing operations
+- `session/set_mode` - Change operating mode
+
+**Client Methods (agent → client):**
+- `session/update` - Send progress updates
+- `session/request_permission` - Request user approval
+- `fs/read_text_file` - Read file contents
+- `fs/write_text_file` - Write file contents
+- `terminal/create` - Create terminal
+- `terminal/output` - Get terminal output
