ManageEngine Endpoint Central MCP Server

ManageEngine Endpoint Central — MCP Server

A Python server that exposes 106 ManageEngine Endpoint Central REST API endpoints as MCP tools, enabling Gemini Enterprise to query and manage organizational endpoints through natural language.

What This Does

End users ask questions in Gemini Enterprise (Google's AI assistant) such as:

  • "Which systems have critical patches pending?"

  • "Show me all devices with BitLocker not enabled"

  • "List software installed on computer XYZ"

  • "Approve patch ID 12345 on all Windows systems"

Gemini selects and calls the appropriate MCP tool on this server, which in turn calls the ManageEngine Endpoint Central REST API and returns the data.
