"""Standards MCP server.

Serves the hand-authored `standards` bundle (the application blueprint plus the
library registry and the runnable template) and adds discovery/scaffolding
helpers so an agent can find the right internal library — and pull exact
template code — before writing any infrastructure.

Resources:
    docs://index, docs://nav, docs://modules/{module}   (from the base server)
    docs://spec                                      (the pinned auth-server OpenAPI contract)
    registry://libraries                             (the structured catalog)
    registry://components                            (the app template component index)
    registry://client                                (the client template component index)
    registry://drone                                 (the CI template index)
    registry://release                               (the release template index)
    registry://repos                                 (the repository inventory)

Tools:
    ping                (from the base server)
    find_library        (capability -> matching libraries + MCP endpoints)
    list_app_components (the template component kinds)
    get_app_component   (kind -> exact template file)
    get_app_template    (the whole app skeleton as a path -> content map)
    list_client_components (the client template component kinds)
    get_client_component   (kind -> exact client template file)
    get_client_template    (the whole client skeleton as a path -> content map)
    list_drone_templates (the three CI shapes: PyPI package / npm package / Docker deployment)
    get_drone_template  (kind -> exact .drone.yml template)
    list_release_templates (the changelog + version-file artefacts)
    get_release_template  (kind -> exact release template file)
    list_repos          (the covered repositories: type, path, version source)

Prompts:
    intake              (the questions to gather before building)
    build               (the two axes -> deterministic build prompt)
    start_app           (combined entry: intake, then build)
    trial               (self-contained trial build into a scratch dir)
    compliance          (remediate repos against the CI + versioning standard)
    release             (agent-assisted tagging after the release MR is merged)
