What Is the MCP Server

The MCP Server exposes ORBSIS capabilities to MCP-enabled AI clients through the Model Context Protocol. Users can state a business goal in a conversation, and the AI client can call authorized ORBSIS tools to query or perform operations. MCP does not replace the REST API: use the REST API for stable system integrations, batch processing, or backend orchestration; use MCP for natural-language queries, assisted analysis, and operations that include human confirmation.
