Get a list of all users in the workspace with their basic profile information
AI agents call slack_get_users to retrieve information from Helm Chart CLI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and retrieves user profile information from Slack. It does not create, modify, delete, or execute any actions. The blast radius is low since exposure of public user profile information in a workspace context is minimally harmful, though it does reveal organizational structure.
From the tool's definition Tool name is 'slack_get_users' and description states it 'Get a list of all users in the workspace with their basic profile information'. This retrieves user data without modification or side effects.

Attacks that exploit this kind of access
Get a list of all users in the workspace with their basic profile information. It is categorised as a Read tool in the Helm Chart CLI MCP Server, which means it retrieves data without modifying state.
Register the Helm Chart CLI MCP server in PolicyLayer and add a rule for slack_get_users: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Helm Chart CLI. Nothing to install.
slack_get_users is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the slack_get_users rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for slack_get_users. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
slack_get_users is provided by the Helm Chart CLI MCP server (jeff-nasseri/servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
