What build_claim_graph does on Nodebench
AI agents call build_claim_graph 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 build_claim_graph is rated Low
The tool reads and analyzes input data (a source packet) to extract and structure claims and evidence into a graph. It does not modify, delete, execute, or commit any financial operations — it purely processes and returns structured analytical output.
From the tool's definition Extract claims from a source packet and link each claim to its evidence. Returns a directed graph of claims with supporting/contradicting evidence
Attacks that exploit this kind of access
The rule that runs build_claim_graph 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 build_claim_graph, this is the rule to start with:
build_claim_graph 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 build_claim_graph call is checked against it from then on.
Questions about build_claim_graph
Extract claims from a source packet and link each claim to its evidence. Returns a directed graph of claims with supporting/contradicting evidence, confidence per claim, and whatWouldChangeMyMind for each. 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 build_claim_graph: 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.
build_claim_graph 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 build_claim_graph 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 build_claim_graph. 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.
build_claim_graph 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.
