## Overview

`py-mcp-installer-service` is a comprehensive Python library for installing and managing [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) servers across multiple AI coding platforms. It provides automatic platform detection, smart installation method selection, and atomic configuration updates with validation and auto-fix capabilities.

### Key Features

- **Platform Auto-Detection**: Automatically detects Claude Desktop, Cline, Roo-Code, Continue, Zed, and other MCP-compatible platforms
- **Multi-Format Support**: Handles both modern JSON and legacy cline_mcp_settings.json formats
- **Smart Installation**: Chooses optimal installation method (uv run, pipx, direct, python -m)
- **Atomic Operations**: All configuration changes are atomic with validation and rollback
- **Legacy Migration**: Automatically migrates legacy format configurations to modern JSON
- **Comprehensive Validation**: Validates configurations, detects conflicts, and suggests fixes
- **Auto-Fix Capabilities**: Can automatically repair common configuration issues
- **Dry-Run Mode**: Preview all changes before applying them

### Supported Platforms

| Platform | Scope | Format | Strategy | Config Location |

## Installation

### As Standalone Library

```bash
# From PyPI (when published)
pip install py-mcp-installer

# From source
pip install git+https://github.com/bobmatnyc/py-mcp-installer-service.git
```

### Development Install

```bash
git clone https://github.com/bobmatnyc/py-mcp-installer-service.git
cd py-mcp-installer-service
pip install -e .
```

### As Submodule in Another Project

```bash
# Add as git submodule
git submodule add https://github.com/bobmatnyc/py-mcp-installer-service.git src/services/py_mcp_installer

# Initialize and update
git submodule update --init --recursive

# Use in your code
from py_mcp_installer import MCPInstaller
```

## Quick Start

```python
from py_mcp_installer import MCPInstaller

# Auto-detect platform and install server
installer = MCPInstaller.auto_detect()
result = installer.install_server(
    name="mcp-ticketer",
    command="mcp-ticketer",
    args=["mcp"],
    description="Ticket management interface"
)

if result.success:
    print(f"✅ Installed on {result.platform.value} using {result.method.value}")
    print(f"Config: {result.config_path}")
else:
    print(f"❌ Failed: {result.message}")
```

## Features

### Platform Auto-Detection

Automatically detects which MCP-compatible platforms are installed:

```python
from py_mcp_installer import MCPInstaller

installer = MCPInstaller.auto_detect(verbose=True)
print(f"Detected platform: {installer.platform.value}")
```

### Smart Installation Method Selection

Chooses the best installation method based on your environment:

```python
from py_mcp_installer import MCPInstaller, InstallMethod

# Let installer choose best method
installer = MCPInstaller.auto_detect()
result = installer.install_server(name="my-server", command="my-command")

# Or specify method explicitly
result = installer.install_server(
    name="my-server",
    command="uv",
    args=["run", "my-package"],
    method=InstallMethod.UV_RUN
)
```

### Atomic Configuration Updates

All configuration changes are atomic with automatic validation:

```python
# Changes are validated before being written
result = installer.install_server(
    name="my-server",
    command="invalid-command"  # Will be validated
)

# On failure, original config is preserved
if not result.success:
    print(f"Config unchanged: {result.message}")
```

### Legacy Format Migration

Automatically migrates old cline_mcp_settings.json to modern format:

```python
from py_mcp_installer.migration import migrate_legacy_config

success = migrate_legacy_config(
    legacy_path=".continue/cline_mcp_settings.json",
    target_path=".continue/config.json",
    backup=True  # Creates .bak file
)
```

### Comprehensive Validation

Validate and inspect existing configurations:

```python
from py_mcp_installer.inspector import MCPInspector

inspector = MCPInspector(config_path=".continue/config.json")
issues = inspector.inspect()

for issue in issues:
    print(f"{issue.severity}: {issue.message}")
    if issue.auto_fix_available:
        print(f"  Fix: {issue.suggested_fix}")
```

### Auto-Fix Capabilities

Automatically repair common configuration issues:

```python
from py_mcp_installer.inspector import MCPInspector

inspector = MCPInspector(config_path=".continue/config.json")
fixed = inspector.auto_fix()

print(f"Fixed {len(fixed)} issues")
```

### Dry-Run Mode

Preview changes before applying:

```python
installer = MCPInstaller.auto_detect(dry_run=True, verbose=True)
result = installer.install_server(name="test-server", command="test")

# No actual changes made, but full validation performed
print(f"Would install: {result.success}")
print(f"Would write to: {result.config_path}")
```

## Usage Examples

### Basic Installation

```python
from py_mcp_installer import MCPInstaller

installer = MCPInstaller.auto_detect()
result = installer.install_server(
    name="mcp-github",
    command="npx",
    args=["-y", "@modelcontextprotocol/server-github"],
    description="GitHub MCP server"
)

print(f"Installed: {result.success}")
```

### Installation with Environment Variables

```python
result = installer.install_server(
    name="mcp-ticketer",
    command="mcp-ticketer",
    args=["mcp"],
    env={
        "LINEAR_API_KEY": "your-api-key",
        "GITHUB_TOKEN": "your-token"
    }
)
```

### List Installed Servers

```python
servers = installer.list_servers()
for server in servers:
    print(f"{server.name}: {server.command} {' '.join(server.args or [])}")
```

### Inspect and Fix Configuration

```python
from py_mcp_installer.inspector import MCPInspector

# Inspect for issues
inspector = MCPInspector(config_path=".continue/config.json")
issues = inspector.inspect()

# Auto-fix what we can
fixed = inspector.auto_fix()
print(f"Fixed {len(fixed)} issues automatically")

# Report remaining issues
remaining = inspector.inspect()
for issue in remaining:
    if not issue.auto_fix_available:
        print(f"Manual fix needed: {issue.message}")
```

### Migrate Legacy Configuration

```python
from py_mcp_installer.migration import migrate_legacy_config

success = migrate_legacy_config(
    legacy_path=".continue/cline_mcp_settings.json",
    target_path=".continue/config.json",
    backup=True,
    preserve_legacy=False  # Remove old file after migration
)

if success:
    print("✅ Migration complete")
```

### Uninstall Server

```python
success = installer.uninstall_server(name="mcp-ticketer")
print(f"Uninstalled: {success}")
```

### Specific Platform and Scope

```python
from py_mcp_installer import MCPInstaller, Platform, Scope

# Install to specific platform
installer = MCPInstaller(platform=Platform.CLAUDE_DESKTOP)

# Install globally vs. project-scoped
result = installer.install_server(
    name="global-server",
    command="server-cmd",
    scope=Scope.GLOBAL
)
```
