AI agents call get_version to retrieve information from Psamvault without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool merely retrieves and returns a version number, which is informational metadata. It does not access credentials, modify any data, execute code, delete resources, or involve financial transactions. This is a typical low-risk information query appropriate for the Read category with low severity due to minimal blast radius if misused.
From the tool's definition Tool returns version information ('Return the installed psamvault-mcp version'). This is a read-only query with no side effects, state modifications, or access to sensitive data beyond a version string.
Attacks that exploit this kind of access
[🛠 Entry & Orientation] Return the installed psamvault-mcp version. No session or login required. It is categorised as a Read tool in the Psamvault MCP Server, which means it retrieves data without modifying state.
Register the Psamvault MCP server in PolicyLayer and add a rule for get_version: 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 Psamvault. Nothing to install.
get_version 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 get_version 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 get_version. 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.
get_version is provided by the Psamvault MCP server (psam-717/psamvault-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
