Support reading the URL from:

• environment variables
• files

Yeah, we're aware the current situation (secrets in settings) is not great for MCPs in Zed. We've discussed a system whereby mcp settings are templates and can draw from the environment or from the platform secrets store (e.g. macOS keychain) explicitly.

Something like:

{
  "foo": {
    "command": {
      "path": "npx",
      "args": ["run", "@github/foo"]
      "env": {
        "GITHUB_TOKEN": "${secrets.github_token}",
        "ANTHROPIC_API_KEY": "${env.ANTHROPIC_API_KEY}"
      },
    }
  }
}

No further details/timeline but it's on our radar and something we hope to do in the near future.
Thanks for reporting.

Cool, amazing!

Being able to read files would great too since that's how some secrets managers work.
