Get descriptions of properties of all relationships in the knowledge graph.
AI agents call get_relationship_metadata to retrieve information from MCP GeneLab Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs pure data retrieval to fetch metadata describing relationships in the knowledge graph. It has no side effects, cannot modify data, and does not execute external operations or commands. It is a straightforward Read category operation with minimal blast radius—exposing relationship metadata would not compromise data integrity or enable harmful actions.
From the tool's definition Tool name 'get_relationship_metadata' and description 'Get descriptions of properties of all relationships in the knowledge graph' indicate a read-only query operation that retrieves metadata about the knowledge graph structure without modifying any data.
Attacks that exploit this kind of access
Get descriptions of properties of all relationships in the knowledge graph. It is categorised as a Read tool in the MCP GeneLab Server MCP Server, which means it retrieves data without modifying state.
Register the MCP GeneLab Server MCP server in PolicyLayer and add a rule for get_relationship_metadata: 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 MCP GeneLab Server. Nothing to install.
get_relationship_metadata 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_relationship_metadata 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_relationship_metadata. 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_relationship_metadata is provided by the MCP GeneLab Server MCP server (sbl-sdsc/mcp-genelab). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
