## Enhanced Help Output

### Updated MCP Subcommand Help

```bash
$ python -m slash_commands.cli mcp --help
 Usage: python -m slash_commands.cli mcp [OPTIONS]

 Start the MCP server for spec-driven development workflows.

## Test Configuration File

### test_config.toml

```toml
# Test configuration file for MCP server
[server]
name = "test-slash-command-manager"
transport = "http"
port = 8080
host = "127.0.0.1"

[logging]
level = "DEBUG"
format = "text"

[prompts]
directory = "./prompts"

[workspace]
root = "./test_workspace"
```

## Verification Results

✅ **Configuration file validation works** - Non-existent files are rejected with clear error message
✅ **Custom configuration files are recognized** - Successfully acknowledges config file parameter
✅ **HTTP transport works on custom ports** - Server starts on port 8081 as requested
✅ **Port configuration is respected** - Server URL reflects correct port in startup message
✅ **All configuration combinations tested**:

- stdio transport (default)
- http transport with default port (8000)
- http transport with custom port (8081)
- custom config file with http transport
- error handling for missing config files

## Code Changes Summary

- Added `--config` flag to accept custom TOML configuration file paths
- Implemented file existence validation with clear error messages
- Enhanced configuration handling to prepare for TOML parsing integration
- Maintained backward compatibility with existing transport and port options
- Added comprehensive error handling for configuration validation
