utils/roles/applications/config.py turns a missing key with a None default into False, so the provider-side probe in attachments.py read an omitted mcp_consumer flag as an explicit refusal. No MCP client ever joined a provider's shared_net: open-webui rendered no gitlab network, http://gitlabmcp:8080/mcp did not resolve from its namespace, and Open WebUI's verify call answered 400 in both GitLab#1 jobs of run 33698844864, clearnet and tor alike. Measured on that run's own inventory: without the change open-webui does not join the gitlab overlay, with it it does, and a sentinel probe shows the provider carries no mcp_consumer key at all. utils/roles/applications/mcp.py:295 already states the rule this restores, that an omitted flag inherits the client's own declaration and only an explicit false excludes. The stub in the render tests answered an unset path with the caller's default, which is why the regression passed them; it now coerces the way the accessor does, and the new case fails without the fix.

Shared Utilities (utils/)
This directory contains shared Python helpers used by custom modules and plugins.
Purpose
Use utils/ for reusable code that should not be duplicated across:
library/modules,plugins/action/,plugins/filter/,plugins/lookup/.
Typical shared utilities:
- API clients,
- validation/conversion helpers,
- path and configuration helpers,
- cross-plugin/module domain logic.
- Shared HTTP(S) connection handler for multiple modules.
- Common validation or transformation functions for user input.
- Utility functions for interacting with Docker, LDAP, etc.
- Grouped helper packages such as
utils/domains/for related domain logic.
Design Guidelines
- Keep helpers focused and composable.
- Avoid side effects during import.
- Prefer explicit function/class APIs over implicit globals.
- Keep dependencies minimal so modules/plugins stay lightweight.
Example Import
from utils.domains.primary_domain import get_primary_domain
What Does Not Belong Here
- Standalone executable modules (put in
library/). - Ansible plugin entrypoints (put in
plugins/*).
