What list_api_keys does on EchoRelay
AI agents call list_api_keys 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_api_keys is rated Low
This tool retrieves and queries API key metadata without returning sensitive plaintext secrets or enabling modification, deletion, or execution. It has no side effects and poses minimal risk if misused by an agent, as metadata alone cannot be used to compromise the system. Classification as Read with low severity is appropriate.
From the tool's definition Tool name is 'list_api_keys' and description states 'List the project's inbound API keys (metadata only — the secret plaintext is never returned).' The word 'List' and explicit statement that only metadata is returned with no secrets exposed indicates a…

The rule that runs list_api_keys 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_api_keys, this is the rule to start with:
list_api_keys 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_api_keys call is checked against it from then on.
Questions about list_api_keys
List the project's inbound API keys (metadata only — the secret plaintext is never returned). 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_api_keys: 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_api_keys 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_api_keys 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_api_keys. 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_api_keys 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.
