What get_packet_lineage does on Nodebench
AI agents call get_packet_lineage to retrieve information from Nodebench without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_packet_lineage is rated Low
This tool queries and retrieves lineage information about packets or entities—a read-only diagnostic operation. It has no side effects, does not execute code, does not modify state, and does not delete data. The blast radius of misuse is minimal; an AI agent could only retrieve lineage information it may not have intended to access, not cause irreversible harm or trigger external operations.
From the tool's definition Tool name 'get_packet_lineage' and description 'Trace the full derivation chain for a packet or entity' indicate a retrieval/query operation that traces historical data lineage without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
The rule that runs get_packet_lineage safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_packet_lineage, this is the rule to start with:
get_packet_lineage is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every get_packet_lineage call is checked against it from then on.
Questions about get_packet_lineage
Trace the full derivation chain for a packet or entity. It is categorised as a Read tool in the Nodebench MCP Server, which means it retrieves data without modifying state.
Register the Nodebench MCP server in PolicyLayer and add a rule for get_packet_lineage: 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 Nodebench. Nothing to install.
get_packet_lineage 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_packet_lineage 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_packet_lineage. 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_packet_lineage is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
