A Model Context Protocol (MCP) server for Radicle CLI with versioning support.

## Features

- **Version Detection**: Automatically detects Radicle CLI version at startup
- **Version Management**: Supports semantic versioning with base definitions and incremental updates
- **Command Validation**: Validates commands against version definitions
- **Deprecation Handling**: Warns about deprecated/obsolete features
- **Hybrid Tool Approach**: Dedicated tools for common commands + generic executor
- **Error Handling**: Structured error responses with JSON output when possible

## Supported Commands

### Dedicated Tools
The server automatically generates dedicated MCP tools for all Radicle commands and subcommands based on the installed version. For Radicle 1.5.0, this includes **71 dedicated tools**:

**Main Commands:**
- `rad_auth`, `rad_block`, `rad_checkout`, `rad_clean`, `rad_clone`
- `rad_cob`, `rad_config`, `rad_follow`, `rad_fork`, `rad_help`
- `rad_id`, `rad_inbox`, `rad_init`, `rad_inspect`, `rad_issue`
- `rad_ls`, `rad_node`, `rad_patch`, `rad_path`, `rad_remote`
- `rad_seed`, `rad_self`, `rad_stats`, `rad_sync`, `rad_unblock`
- `rad_unfollow`, `rad_unseed`

**Subcommand Examples:**
- `rad_issue_open`, `rad_issue_list`, `rad_issue_show`, `rad_issue_edit`
- `rad_patch_open`, `rad_patch_list`, `rad_patch_show`, `rad_patch_merge`
- `rad_node_start`, `rad_node_stop`, `rad_node_status`, `rad_node_logs`
- `rad_config_get`, `rad_config_set`, `rad_config_schema`
- `rad_cob_create`, `rad_cob_show`, `rad_cob_update`, `rad_cob_log`

### Generic Tool
- `rad_execute`: Execute any rad command (fallback for unsupported commands)

### Version Support
- **Supported Versions**: 1.1.0, 1.2.0, 1.3.0, 1.4.0, 1.5.0
- **Version Resolution**: Falls back to closest available version if exact match not found
- **Warning System**: One-time warnings for version mismatches and deprecated features
- **Dynamic Tool Generation**: Tools are generated based on the specific version's capabilities

## Installation

### PyPI (Recommended)
```bash
pip install radicle-mcp-server
```

### Development
```bash
# Clone the repository
git clone <repository-url>

# Install dependencies
cd radicle-mcp-server
uv sync
```

## Running the Server

### Using Just (Recommended)
```bash
just run                    # Stdio transport (default)
just run-http              # HTTP transport on localhost:8000
```

### Using UV Directly
```bash
uv run python -m src.server                    # Stdio transport
uv run python -m src.server --transport http   # HTTP transport
```

## MCP Client Configuration

### OpenCode
Add to your MCP configuration:
```json
{
  "mcpServers": {
    "radicle": {
      "command": "radicle-mcp-server"
    }
  }
}
```

### Claude Desktop
Add to `claude_desktop_config.json`:
```json
{
  "mcpServers": {
    "radicle": {
      "command": "radicle-mcp-server"
    }
  }
}
```

### Development (from source)
If you're developing from source, use:
```json
{
  "mcpServers": {
    "radicle": {
      "command": "uv",
      "args": ["run", "python", "-m", "src.server"],
      "cwd": "/path/to/radicle-mcp-server"
    }
  }
}
```

## Usage

The server provides MCP tools that can be used with any MCP-compatible client. It automatically detects the installed Radicle CLI version and adapts its behavior accordingly.

## Development

This project uses:
- **FastMCP**: For MCP server implementation
- **uv**: For dependency management
- **Python 3.13+**: For modern type annotations

## Versioning System

The versioning system uses YAML definitions stored in `src/definitions/`:

- `radicle-1.1.0.yaml` through `radicle-1.5.0.yaml`: Complete command definitions for each version
- `schema.py`: Validation schema and data structures
- Each version file contains all available commands, subcommands, options, and examples

This design allows for efficient handling of semantic versioning while maintaining backward compatibility.
