Converts the CredentialsNotConfiguredError sentinel to a user-facing ToolError
in tool_error_handler, including the exact CREDENTIALS_ENV_PATH so users know
where to create the .env file. Removes the now-invalid per-tool elicitation
test (replaced by 2 new tests for the handler conversion behavior).
- _write_env now creates CREDENTIALS_DIR (mode 700) and writes credentials
to CREDENTIALS_ENV_PATH (mode 600) instead of PROJECT_ROOT/.env
- On first run (no .env yet), seeds file content from .env.example to
preserve comments and structure
- elicit_and_configure catches NotImplementedError from ctx.elicit() so
clients that don't support elicitation return False gracefully instead
of propagating the exception
- Updated test_elicit_and_configure_writes_env_file to patch CREDENTIALS_DIR
and CREDENTIALS_ENV_PATH instead of PROJECT_ROOT
- Added 5 new tests covering dir/file permissions, .env.example seeding,
in-place credential update, and NotImplementedError guard
Introduce a version-agnostic credential directory (~/.unraid-mcp, overridable
via UNRAID_CREDENTIALS_DIR env var) and surface it as CREDENTIALS_DIR and
CREDENTIALS_ENV_PATH module-level constants. Prepend the canonical .env path to
dotenv_paths so all runtimes (plugin, uv, Docker) resolve credentials from the
same stable location without relying on versioned plugin cache paths.
make_graphql_request now reads credentials from the settings module at call
time (via a local import) instead of relying on module-level names captured at
import time. When either credential is missing it raises CredentialsNotConfiguredError
(not ToolError), allowing callers to trigger elicitation rather than surfacing a
generic error to the MCP client.
Updated tests/test_client.py and tests/http_layer/test_request_construction.py
to patch unraid_mcp.config.settings.* instead of the now-removed client-module
attrs, and to expect CredentialsNotConfiguredError on missing credentials.
