MCP servers are decentralized, posing a security risk as anyone can run a server, even bad actors.
Local servers, though generally safer, can still introduce risks if the server binary is from an unknown source.
Remote MCP connections require authentication, origin verification, and encrypted transport for security.
Best practices for using MCP include auditing source code, running servers in isolated environments, using authentication for remote servers, avoiding shared links, and maintaining a whitelist of approved servers.
