AI agents call tdarr_get_nodes 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 retrieves and displays information about connected nodes in the Tdarr distributed transcoding system. It is a read-only query operation with no side effects—it neither creates, modifies, deletes, nor executes any external operations. The blast radius if misused is minimal; an agent could only gain visibility into the system's worker topology.
From the tool's definition Tool name 'tdarr_get_nodes' with description 'Get connected nodes information' indicates a retrieval operation that queries the state of connected worker nodes without modifying any data or triggering transcoding operations.
Attacks that exploit this kind of access
Get connected nodes information. 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_get_nodes: 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_get_nodes 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_get_nodes 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_get_nodes. 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_get_nodes 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.
