slack_configure · Git Steer MCP: Risk & Policy

WHAT IT DOES

What slack_configure does on Git Steer

AI agents use slack_configure to create or update resources in Git Steer — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Git Steer environment.

WHY IT NEEDS A POLICY

Why slack_configure needs a policy

This tool creates or modifies configuration data (Slack webhook URL storage) in the state repository, qualifying it as Write. Severity is elevated to high because: (1) webhook URLs are sensitive credentials that could enable unauthorized Slack notifications if misconfigured, (2) improper configuration could redirect notifications to attacker-controlled Slack workspaces, and (3) the state repository stores this…

From the tool's definition 'Configure Slack webhook URL for notifications. Stores in state repo config.' — the tool modifies configuration by storing a webhook URL, a write operation with external integration implications.

Verdict

slack_configure Rate-limited

slack_configure stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
