policies-list
AI agents call policies-list to retrieve information from Vault MCP Server (mschuchard) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The '-list' suffix is a strong signal for read-only enumeration operations. In Vault, listing policies retrieves their names and metadata without modification. The empty description reduces confidence slightly, but sibling tools like 'audit-devices-list' and 'authentication-engines-list' on the same server confirm the pattern: '-list' tools perform read operations.
From the tool's definition Tool name 'policies-list' indicates a list operation; description is empty but naming convention and server context (Vault MCP for policy management) strongly suggest data retrieval with no side effects.
Attacks that exploit this kind of access
policies-list. It is categorised as a Read tool in the Vault MCP Server (mschuchard) MCP Server, which means it retrieves data without modifying state.
Register the Vault MCP Server (mschuchard) MCP server in PolicyLayer and add a rule for policies-list: 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 Vault MCP Server (mschuchard). Nothing to install.
policies-list 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 policies-list 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 policies-list. 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.
policies-list is provided by the Vault MCP Server (mschuchard) MCP server (mschuchard/vault-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
