Best practices for managing secrets in hosted MCP deployments

By PulseAugur Editorial · [1 sources] ·

This article discusses best practices for managing secrets, such as API tokens, in hosted MCP deployments. It emphasizes storing secrets in the platform's environment variable store or a dedicated secret manager, rather than hardcoding them into configuration files or repositories. The author recommends using a gateway pattern to inject credentials at the edge, ensuring the MCP server and agent never directly handle the secret.
