MCP Tool Description (Exact)

Dataverse environment variables — list/detail/create/update/delete/clear.
- list: optional solution_name, max_records
- detail: variable_name (Display Name or schema name)
- create: solution_name (REQUIRED) + display_name + type. Optional: default_value, value, description
- update: variable_name (Display Name or schema name). Optional: display_name, default_value, value, description
- delete: variable_name (Display Name or schema name; definition + value, irreversible)
- clear: variable_name (Display Name or schema name; current value only → reverts to default)

CREATE uses the publisher prefix from solution_name directly. confirmed_prefix is optional and only validates the resolved prefix when supplied.
solution_name is REQUIRED for create — if not provided by the user, ask; never search or guess.

Current value overrides default. Type immutable after creation. Usually no publish needed.

WHEN TO USE:
- Inspect / list env vars in a solution (config secrets, feature flags, etc.)
- Create or update a definition + current value
- Clear current value to revert to default; delete to remove definition entirely

SAFETY:
- delete removes definition + current value (irreversible); clear removes current value only

max_records	integer	No	50	list only.
display_name	string	No	""	Required: create.
type	string	No	""	string/number/boolean/json/datasource/secret. Required: create. Ignored: update.
default_value	string	No	""	-
