AI agents call list_environments to retrieve information from Secr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries environment configuration data, which is a Read operation. However, the medium severity reflects that environment data often reveals infrastructure topology, names, credentials references, or configuration details that could inform downstream attacks or unauthorized secret access if exposed to a compromised agent.
From the tool's definition Tool name is 'list_environments' with description 'List environments for a project' — a retrieval operation with no stated modifications or deletions.
Attacks that exploit this kind of access
List environments for a project. It is categorised as a Read tool in the Secr MCP Server, which means it retrieves data without modifying state.
Register the Secr MCP server in PolicyLayer and add a rule for list_environments: 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 Secr. Nothing to install.
list_environments 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_environments 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_environments. 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_environments is provided by the Secr MCP server (secr-dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
