WHAT IT DOES

What marchward_execute does on Mcp Server

AI agents invoke marchward_execute to trigger actions in Mcp Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why marchward_execute is rated High

The tool explicitly 'runs' an action, which is the definition of Execute category. While Marchward provides guardrails (approval gates, spend caps, audit logs), the tool itself triggers external operations whose effects depend on what action is passed as argument.

From the tool's definition Tool name 'marchward_execute' combined with description 'Run an action through Marchward' indicates execution of actions.
