Implementation Reference
- src/mcp_server_appwrite/server.py:71-71 (registration)Registers the TablesDB Appwrite service with the ToolManager using service name 'tables_db'. This enables dynamic tool generation for all public methods of TablesDB, including 'tables_db_increment_row_column' which wraps TablesDB.increment_row_column.
tools_manager.register_service(Service(TablesDB(client), "tables_db")) - src/mcp_server_appwrite/server.py:94-94 (registration)Default registration of TablesDB service if no specific services are enabled.
tools_manager.register_service(Service(TablesDB(client), "tables_db")) - Generates the tool name by prefixing the service name ('tables_db') to the method name ('increment_row_column'), producing 'tables_db_increment_row_column'.
tool_name = self._method_name_overrides.get(name, f"{self.service_name}_{name}") - Dynamically generates the JSON schema for the tool input based on the method's type hints, docstring, and signature.
tool_definition = Tool( name=tool_name, description=f"{docstring.short_description or "No description available"}", inputSchema={ "type": "object", "properties": properties, "required": required } - The generic MCP tool handler that resolves the tool by name, retrieves the bound Appwrite SDK method, invokes it with arguments, and formats the result as text content.
