Return the installed version of the mcp-spotify server.
AI agents call get_server_version to retrieve information from Mcp Spotify without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple informational query that retrieves metadata about the server itself. It does not create, modify, delete, or execute any operations, nor does it access sensitive user data. The blast radius of misuse is minimal, as version information is typically non-sensitive and immutable.
From the tool's definition Tool named 'get_server_version' returns version information with no side effects or data modifications. The description explicitly states it 'Return[s] the installed version' — a pure query operation.
Attacks that exploit this kind of access
Return the installed version of the mcp-spotify server. It is categorised as a Read tool in the Mcp Spotify MCP Server, which means it retrieves data without modifying state.
Register the Mcp Spotify MCP server in PolicyLayer and add a rule for get_server_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 Mcp Spotify. Nothing to install.
get_server_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_server_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_server_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_server_version is provided by the Mcp Spotify MCP server (obrien-matthew/mcp-spotify). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
