What is your preferred way to manage them?

[devenjarvis]

The 1pass CLI is great! However if you aren’t using 1password as your secrets vault, I’m building an open source, vault-agnostic alternative called RunSecret (https://github.com/runsecret/rsec)

You may want to do your own Show HN about it, so folks don't have to be "MCP curious" to find out that it exists

That said, given https://github.com/runsecret/rsec#aws-secrets-manager presumably in order to keep AWS credentials off disk one would then have to have this?

    "vantage-mcp-server": {
      "command": "/opt/homebrew/bin/aws-vault",
      "args": [
      "exec", "--region=us-east-1", "my-awesome-profile",
      "--", "/opt/homebrew/bin/rsec", "run",
      "--", "/opt/homebrew/bin/vantage-mcp-server"
      ],
      "env": {"VANTAGE_BEARER_TOKEN":  "rsec://012345678912/sm.aws/VantageBearerToken?region=us-east-1"}
    }

in contrast to the op binary that is just one level of indirection, since they already handshake with the desktop app for $(op login) purposes

Vantage engineer who worked on this feature here. The security posture of MCP servers is still in its early stages (see “The ‘S’ in MCP Stands for Security” from three weeks ago [https://elenacross7.medium.com/%EF%B8%8F-the-s-in-mcp-stands...]). The recommendations above to use something like the 1Password CLI wrapper when invoking an MCP server seem sound.

That being said, an easier-to-distribute user experience would be to leverage short-lived OAuth tokens that LLM clients such as Claude or Goose ultimately manage for the user. We’re exploring these avenues as we develop the server.

If your service is running in AWS, use the native IAM identity loading from ECS, EKS, EC2, etc. If it's your laptop, set AWS_PROFILE and let the SDK load the temporary creds from ~/.aws.

If you really really really need to use static creds on your laptop, use aws-vault to export them, or ephemeral creds generated from them, into your environment.

1Password’s CLI op does a reasonably good job of this
