DSS MCP Server Plugins

This directory contains dynamically loaded plugins for the DSS MCP server.

Plugin Contract:
- Each plugin is a .py file in this directory
- Must export TOOLS: List[types.Tool] with MCP tool definitions
- Must have a handler class with execute_tool(name, arguments) method
- Optional: export PLUGIN_METADATA dict with name, version, author

Example Plugin Structure:
    from mcp import types

    PLUGIN_METADATA = {
        "name": "My Plugin",
        "version": "1.0.0",
        "author": "DSS Team"
    }

    TOOLS = [
        types.Tool(name="my_tool", description="...", inputSchema={...})
    ]

    class PluginTools:
        async def execute_tool(self, name, arguments):
            if name == "my_tool":
                return {"result": "success"}

Developer Workflow:
1. Copy _template.py to new_plugin.py
2. Edit TOOLS list and PluginTools class
3. (Optional) Create requirements.txt if plugin needs dependencies
4. Run: ../install_plugin_deps.sh (if dependencies added)
5. Restart MCP server: supervisorctl restart dss-mcp
6. Plugin tools are immediately available to all clients

Dependency Management:
- If your plugin needs Python packages, create a requirements.txt file
- Place it in the same directory as your plugin (e.g., plugins/my_plugin/requirements.txt)
- Run ../install_plugin_deps.sh to install all plugin dependencies
- Use --check flag to see which plugins have dependencies without installing

Example plugin with dependencies:
    plugins/
    ├── my_plugin/
    │   ├── __init__.py
    │   ├── tool.py (exports TOOLS and PluginTools)
    │   └── requirements.txt (jinja2>=3.1.2, httpx>=0.25.0)
    └── _template.py

See _template.py for a complete example.
