AI agents call get_node_labels 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.
The tool name and server purpose suggest querying graph structure metadata. The description is empty, lowering confidence slightly, but the naming convention and algorithmic context of sibling tools (all analysis/query operations) strongly indicate this is a read-only retrieval of node label information. No side effects, no data modification, no execution, no financial impact. Classification: Read with low severity.
From the tool's definition Tool name 'get_node_labels' combined with server context (Neo4j Graph Data Science) and sibling tools that are all read-only graph algorithms (shortest paths, centrality, BFS) indicates this retrieves node label metadata from the graph without modification.
Attacks that exploit this kind of access
get_node_labels. 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 get_node_labels: 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.
get_node_labels 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_node_labels 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_node_labels. 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_node_labels 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.
get_node_labels is one line of Neo4j Gds's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
