Sealed

Overview

Sealed is a Model Context Protocol server that provides per-call paid skills for AI agents, executed server-side with inputs sent in and outputs returned back. The processing never leaves the server. By implementing MCP, Sealed enables AI assistants to call these skills as native tools without manual data transfers between applications.

Sealed runs locally via the npm package sealed-mcp, which communicates over stdio with your machine. Setup requires two environment variables: SEALED_API_URL and SEALED_API_KEY for authentication. The latest release is v0.1.0, published under the MIT license with source code available at edwardyen724-g/sealed-mcp on GitHub.

Sealed is listed in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Sealed, claim this listing to verify ownership and keep information up to date.
