AI agents call delta_stepping_shortest_path to retrieve information from Neo4j Gds without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Delta-Stepping Shortest Path is a graph traversal/computation algorithm that reads graph data and returns shortest path results. It does not modify, delete, or write any data, nor does it execute arbitrary code or trigger financial operations.
From the tool's definition 'computes all shortest paths between a source node and all reachable nodes in the graph' — purely a read/query operation with no side effects
Attacks that exploit this kind of access
The Delta-Stepping Shortest Path algorithm computes all shortest paths between a source node and all reachable nodes in the graph. It is categorised as a Read tool in the Neo4j Gds MCP Server, which means it retrieves data without modifying state.
Register the Neo4j Gds MCP server in PolicyLayer and add a rule for delta_stepping_shortest_path: 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 Neo4j Gds. Nothing to install.
delta_stepping_shortest_path 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 delta_stepping_shortest_path 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 delta_stepping_shortest_path. 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.
delta_stepping_shortest_path is provided by the Neo4j Gds MCP server (neo4j-contrib/gds-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
