List members of a team. role: all | maintainer | member.
AI agents call list_team_members to retrieve information from Ghe Mcp Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves team membership information without side effects. It is read-only, consistent with the server's stated 'read-only safety by default' design. The potential security concern is information disclosure of team structure, but within an organization context this is typically low-severity. No code execution, data modification, deletion, or financial operations occur.
From the tool's definition Tool name 'list_team_members' and description 'List members of a team' indicate a retrieval operation with no data modification or external execution. The 'role' parameter filters results but does not alter state.
Attacks that exploit this kind of access
List members of a team. role: all | maintainer | member. It is categorised as a Read tool in the Ghe Mcp Gateway MCP Server, which means it retrieves data without modifying state.
Register the Ghe Mcp Gateway MCP server in PolicyLayer and add a rule for list_team_members: 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 Ghe Mcp Gateway. Nothing to install.
list_team_members 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 list_team_members 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 list_team_members. 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.
list_team_members is provided by the Ghe Mcp Gateway MCP server (mholzinger/ghe-mcp-gateway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
