MCP Gateway

MCP Gateway is an open-source MCP (Model Context Protocol) server that sits between AI assistants (like Claude Desktop) and internal organizational resources such as databases and filesystems. It securely exposes these resources as authenticated MCP tools with full role-based access control, audit logging, and support for SSO (Microsoft Entra ID/Azure AD) and various authentication methods. It is intended for organizations seeking to enable safe, auditable AI-driven access to internal data, with out-of-the-box SQL and filesystem tools, plus the ability to integrate custom tools.
