What each does
SEAL (sealnet-mcp): Local MCP server for SEAL's end-to-end encrypted sharing: your agent hands files, folders or secrets to you or another agent as seals, asks you for a file or secret through a dialog or page, and runs commands with secrets kept out of its output. After pairing, the default delivery route sends a file to the user's SEAL inbox and returns a short handle to the model. Free up to 1 GB per seal.
draw.io MCP (official): The draw.io team's own MCP for opening diagrams (XML, CSV, Mermaid) and reading draw.io shape/reference docs.
