Find the shortest path between two nodes
AI agents call neo4j.shortest_path to retrieve information from Neo4j MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a graph traversal query to find the shortest path between two nodes. It retrieves/computes data without modifying, creating, or deleting any data in the database. It's a read-only analytical operation common in graph databases.

Attacks that exploit this kind of access
Find the shortest path between two nodes. It is categorised as a Read tool in the Neo4j MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Neo4j MCP Server MCP server in PolicyLayer and add a rule for neo4j.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 MCP Server. Nothing to install.
neo4j.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 neo4j.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 neo4j.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.
neo4j.shortest_path is provided by the Neo4j MCP Server MCP server (vpro1032/neo4j-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
