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
| Tool | What it does |
|---|---|
list_mcp_servers | List the MCP servers governed by your Sealgate gateway, with access-control classification and connection status. |
get_session_status | Review recent agent sessions and audit events: what agents did, which data flowed, and any blocked actions. |
Configuration
Set two environment variables, both issued or hosted by your organisation:
| Variable | Description |
|---|---|
SEALGATE_GATEWAY_URL | Base URL of your Sealgate Management API (e.g. https://dashboard.sealgate.ai). |
SEALGATE_API_KEY | Sealgate API key from your dashboard. |
If either is unset, every tool returns a clear configuration message instead of
failing, so registry probes and --help never crash.
Install
Add the server to your MCP client. It runs over stdio via npx.
