What list_members does on EchoRelay
AI agents call list_members to retrieve information from EchoRelay without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_members is rated Low
This tool retrieves and displays project membership information without creating, modifying, or deleting data. It is a read-only query operation with limited blast radius even if misused by an AI agent, as it only exposes project member metadata that the owner could already view through the UI.
From the tool's definition Tool name is 'list_members' and description states it 'List[s] accepted and pending members' — a retrieval operation with no modification or side effects. The 'Owner only' access control does not change the fundamental action of querying/listing data.
Attacks that exploit this kind of access
The rule that runs list_members safely
PolicyLayer is an MCP gateway: it sits between your AI agents and EchoRelay, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_members, this is the rule to start with:
list_members is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect EchoRelay, apply this rule, and every list_members call is checked against it from then on.
Questions about list_members
List accepted and pending members of this project. Shows name/email, role, and whether the invite has been accepted. Owner only. It is categorised as a Read tool in the EchoRelay MCP Server, which means it retrieves data without modifying state.
Register the EchoRelay MCP server in PolicyLayer and add a rule for list_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 EchoRelay. Nothing to install.
list_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_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_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_members is provided by the EchoRelay MCP server (https://mcp.echorelay.dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
