What the publisher says

From the Sealgate repository's README, as published. We do not edit it. Read it on GitHub

Sealgate MCP Server

The Model Context Protocol (MCP) server for Sealgate, the AI data-leak-prevention platform: a security gateway and data firewall that sits between AI agents (Claude, ChatGPT, Cursor, Copilot) and your organisation's data and tools.

This server is a thin MCP proxy. It forwards a small set of tool calls to a Sealgate gateway, which you configure with two environment variables. Sealgate runs managed release hosts (the remote MCP gateway at mcp.sealgate.ai and the Management API at dashboard.sealgate.ai), and demo or self-hosted orgs run their own, so this bridge stays host-agnostic: you supply the URL and key.

Tools

Connect to the hosted gateway

Sealgate runs a managed remote MCP gateway at https://mcp.sealgate.ai/mcp. It is a per-user proxy that aggregates every MCP server you have enabled behind one Streamable HTTP endpoint and enforces Sealgate's access-control policies on every call. There is nothing to install: point your client at the endpoint and sign in through the browser.

Endpoint:   https://mcp.sealgate.ai/mcp
Transport:  streamable HTTP (remote, not stdio)
Auth:       OAuth 2.1 in the browser, no key to paste
