Nine roles reached their MCP surface as the deployment administrator or with
an account password kept beside the account in credentials. A Moodle site
admin bypasses every capability check, a Nextcloud app password is not
scopable, a Gitea token reads every private repository, and a GitLab token on
root reads every private project. Each role now declares its own principal in
meta/users.yml and provisions it, so the exposed surface is what the service
role permits. jellyfin, zammad and snipe-it kept their account but took its
password from a credential named token; they read the registry too.

Gitea ships no MCP server, so the role runs the project-owned gitea-mcp
package as a sidecar next to it and points it at the instance over the
container network.
Two things the image forces. Its command carries the binary path
explicitly because the image declares no ENTRYPOINT, so a bare flag list
would replace the binary instead of extending it. The port is stringified
because Ansible's native types make a bare lookup an int, and compose
rejects a non-string in a command array.
Keep the surface internal. The public vhost answers a bearerless probe
with an SSO redirect, so the guest spec pins maxRedirects to 0 and
asserts no MCP response is ever served; following the redirect would land
on a login page and pass for the wrong reason.
Calls run with administrator rights, so the tool policy is pinned
read-only and the sidecar starts with the read-only flag and a scope
list.
