## Quick Start

Get started in 5 minutes:

```bash
# Install
git clone https://github.com/ambient-code/mcp
claude mcp add mcp-acp -t stdio mcp/dist/mcp_acp-*.whl

# Configure
mkdir -p ~/.config/acp
cat > ~/.config/acp/clusters.yaml <<EOF
clusters:
  my-cluster:
    server: https://api.your-cluster.example.com:443
    default_project: my-workspace
default_cluster: my-cluster
EOF

# Authenticate
oc login --server=https://api.your-cluster.example.com:443

# Add to Claude Desktop config
{
  "mcpServers": {
    "acp": {
      "command": "mcp-acp"
    }
  }
}
```

**First Command**: `List my ambient sessions that are older than a week`

## Overview

This MCP server provides 27 comprehensive tools for interacting with the Ambient Code Platform, enabling:

- **Session Management**: List, create, delete, restart, clone sessions
- **Label Management**: Tag and organize sessions with custom labels
- **Bulk Operations**: Efficiently manage multiple sessions at once
- **Advanced Filtering**: Filter by status, age, display name, labels, and more
- **Debugging**: Retrieve logs, transcripts, and metrics
- **Cluster Management**: Multi-cluster support with easy switching
- **Safety First**: Dry-run mode on all mutating operations

**Security:** This server implements comprehensive security measures including input validation, command injection prevention, timeout controls, and resource limits. See [SECURITY.md](SECURITY.md) for details.

## Installation

### From PyPI (when published)

### From Source

```bash
git clone https://github.com/ambient-code/mcp
pip install dist/mcp_acp-*.whl
```

**Requirements:**

- Python 3.10+
- OpenShift CLI (`oc`) installed and in PATH
- Access to an OpenShift cluster with ACP

See [QUICKSTART.md](QUICKSTART.md) for detailed installation instructions.

---

## Configuration

### 1. Create Cluster Configuration

Create `~/.config/acp/clusters.yaml`:

```yaml
clusters:
  vteam-stage:
    server: https://api.vteam-stage.xxxx.p3.openshiftapps.com:443
    description: "V-Team Staging Environment"
    default_project: jeder-workspace

  vteam-prod:
    server: https://api.vteam-prod.xxxx.p3.openshiftapps.com:443
    description: "V-Team Production"
    default_project: jeder-workspace

default_cluster: vteam-stage
```

### 2. Configure MCP Client

For Claude Desktop, edit your configuration file:

**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
**Linux**: `~/.config/claude/claude_desktop_config.json`

Add the ACP server:

```json
{
  "mcpServers": {
    "acp": {
      "command": "mcp-acp",
      "args": [],
      "env": {
        "ACP_CLUSTER_CONFIG": "${HOME}/.config/acp/clusters.yaml"
      }
    }
  }
}
```

### 3. Authenticate with OpenShift

```bash
oc login --server=https://api.your-cluster.example.com:443
```

> **Note**: Direct OpenShift CLI authentication is required for testing until the frontend API is available (tracked in PR #558).

## Usage Examples

### List Sessions with Filtering

```
# List only running sessions
List running sessions in my-workspace

# List sessions older than 7 days
Show me sessions older than 7 days in my-workspace

# List sessions by label
List sessions with env=test and team=qa labels in my-workspace

# List sessions sorted by creation date
List sessions in my-workspace, sorted by creation date, limit 20
```

### Label Management

```
# Add labels to a session
Add env=test and team=qa labels to my-session in my-workspace

# List sessions by label
List sessions with env=test label in my-workspace

# Bulk delete sessions by label
Delete all sessions with env=test label in my-workspace (dry-run first)
```

### Delete Session with Dry-Run

```
# Preview what would be deleted
Delete test-session from my-workspace in dry-run mode

# Actually delete
Delete test-session from my-workspace
```

### Bulk Operations

```
# Stop multiple sessions
Stop session-1, session-2, and session-3 in my-workspace

# Delete old sessions with dry-run
Delete old-session-1 and old-session-2 from my-workspace in dry-run mode
```

### Get Session Logs

```
# Get logs from runner container
Get logs from debug-session in my-workspace, runner container, last 100 lines
```

## Architecture

The server is built using:

- **MCP SDK**: Standard MCP protocol implementation
- **OpenShift CLI**: Underlying `oc` commands for ACP operations
- **Async I/O**: Non-blocking operations for performance
- **YAML Configuration**: Flexible cluster management

See [CLAUDE.md](CLAUDE.md#architecture-overview) for complete system design.

---

## Security

This server implements defense-in-depth security:

- **Input Validation**: DNS-1123 format validation for all resource names
- **Command Injection Prevention**: Secure subprocess execution (never shell=True)
- **Resource Exhaustion Protection**: Timeouts and limits on all operations
- **Secure Temporary Files**: Random prefixes, 0600 permissions
- **Path Traversal Prevention**: Configuration and workflow file validation
- **Resource Type Whitelist**: Only agenticsession, pods, event resources
- **Sensitive Data Filtering**: Tokens/passwords removed from logs

See [SECURITY.md](SECURITY.md) for complete security documentation.
