AI agents call tdarr_nodes_version_check to retrieve information from Tdarr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs version verification, which is a non-destructive information retrieval operation. It checks a server property before connection setup but does not create, modify, delete, or execute any commands that would alter system state or have side effects beyond returning version data. No financial, destructive, or execution capabilities are evident.
From the tool's definition Tool name 'tdarr_nodes_version_check' and description 'Verify the server version before establishing a full node connection' indicate a read-only query operation that retrieves version information without modifying any state.
Attacks that exploit this kind of access
Verify the server version before establishing a full node connection. It is categorised as a Read tool in the Tdarr MCP Server, which means it retrieves data without modifying state.
Register the Tdarr MCP server in PolicyLayer and add a rule for tdarr_nodes_version_check: 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 Tdarr. Nothing to install.
tdarr_nodes_version_check 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 tdarr_nodes_version_check 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 tdarr_nodes_version_check. 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.
tdarr_nodes_version_check is provided by the Tdarr MCP server (maximeallanic/tdarr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
