mcs-permission
Consent / permission decorator for the Model Context Standard (MCS).
Provides PermissionDecorator -- a BaseDecorator that gates tool execution
behind a consent callback. Before execute_tool runs, the decorator asks the
client whether the pending tool call (name + arguments) is allowed; on denial it
returns a structured permission_denied result instead of executing.
Installation
pip install mcs-permission
Usage
from mcs.permission.decorator import PermissionDecorator
def ask_user(tool_name, arguments) -> bool:
return input(f"Run {tool_name}? [y/N] ").strip().lower() == "y"
guarded = PermissionDecorator(MyToolDriver(...), consent=ask_user)
orchestrator.add_driver(guarded, label="mail")
It wraps the ToolDriver layer, so the surrounding orchestrator keeps its
process_llm_response loop and calls execute_tool -- the decorator -- beneath
it. Decorators stack: PermissionDecorator(AuthDecorator(RealToolDriver))
checks consent first and handles auth challenges deeper down.
Advertises the "consent" capability and is reachable via
DriverMeta.resolve_capability(driver, SupportsConsent).
