Appwrite MCP Server

Instructions

Implementation Reference

• src/mcp_server_appwrite/server.py:71-71 (registration)

  Registers the TablesDB Appwrite service with tool name prefix 'tables_db'. The 'delete' method on TablesDB becomes the 'tables_db_delete' tool.
  tools_manager.register_service(Service(TablesDB(client), "tables_db"))
• src/mcp_server_appwrite/server.py:94-94 (registration)

  Default registration of the TablesDB service as fallback if no services specified.
  tools_manager.register_service(Service(TablesDB(client), "tables_db"))
• src/mcp_server_appwrite/service.py:73-127 (schema)

  Dynamically generates tool definitions and input schemas for all public methods on the service instance, using name 'tables_db_{method_name}' e.g. 'tables_db_delete'.
  def list_tools(self) -> Dict[str, Dict]: """Lists all available tools for this service""" tools = {} for name, func in inspect.getmembers(self.service, predicate=inspect.ismethod): if name.startswith('_'): # Skip private methods continue original_func = func.__func__ # Skip if not from the service's module if original_func.__module__ != self.service.__class__.__module__: continue # Get the overridden name if it exists tool_name = self._method_name_overrides.get(name, f"{self.service_name}_{name}") docstring = parse(original_func.__doc__) signature = inspect.signature(original_func) type_hints = get_type_hints(original_func) properties = {} required = [] for param_name, param in signature.parameters.items(): if param_name == 'self': continue param_type = type_hints.get(param_name, str) properties[param_name] = self.python_type_to_json_schema(param_type) properties[param_name]["description"] = f"Parameter '{param_name}'" for doc_param in docstring.params: if doc_param.arg_name == param_name: properties[param_name]["description"] = doc_param.description if param.default is param.empty: required.append(param_name) tool_definition = Tool( name=tool_name, description=f"{docstring.short_description or "No description available"}", inputSchema={ "type": "object", "properties": properties, "required": required } ) tools[tool_name] = { "definition": tool_definition, "function": func } return tools
• src/mcp_server_appwrite/server.py:104-123 (handler)

  Generic handler for all tools, including 'tables_db_delete'. Retrieves the bound method from TablesDB.delete and invokes it with arguments.
  async def handle_call_tool( name: str, arguments: dict | None ) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: try: tool_info = tools_manager.get_tool(name) if not tool_info: raise McpError(f"Tool {name} not found") bound_method = tool_info["function"] result = bound_method(**(arguments or {})) if hasattr(result, 'to_dict'): result_dict = result.to_dict() return [types.TextContent(type="text", text=str(result_dict))] return [types.TextContent(type="text", text=str(result))] except AppwriteException as e: return [types.TextContent(type="text", text=f"Appwrite Error: {str(e)}")] except Exception as e: return [types.TextContent(type="text", text=f"Error: {str(e)}")]
• src/mcp_server_appwrite/tool_manager.py:10-14 (helper)

  ToolManager.register_service: adds the tools from the service (including tables_db_delete) to the registry used by list_tools and get_tool.
  def register_service(self, service: Service): """Register a new service and its tools""" self.services.append(service) self.tools_registry.update(service.list_tools())
