WHAT IT DOES

What slack_upload_file does on ScopeGate

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

RISK

Why slack_upload_file is rated Medium

This tool creates new messages/files in Slack channels, which is a Write operation (creates data reversibly). Severity is medium because unauthorized sharing could expose sensitive information to unintended audiences, but the action is reversible (shared content can be deleted). The confidence is slightly below high because the description lacks detail about access controls, but the core functionality is clear.

From the tool's definition Tool name 'slack_upload_file' combined with description 'Share a file or text snippet in a Slack channel' indicates creation/addition of content to Slack, a reversible action.

RECOMMENDED RULE

The rule that runs slack_upload_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ScopeGate, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For slack_upload_file, this is the rule to start with:

slack_upload_file Rate-limited

slack_upload_file 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.
