List all graphs in the AGE
AI agents call list-age-graphs to retrieve information from AGE-MCP-Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about existing graphs without creating, modifying, or deleting any data. It is a read-only operation with minimal blast radius—an AI agent misusing it could only learn what graphs exist, which is a low-severity information disclosure. No side effects or destructive capability.
From the tool's definition Tool name 'list-age-graphs' and description 'List all graphs in the AGE' indicate a query/enumeration operation with no data modification.
Attacks that exploit this kind of access
List all graphs in the AGE. It is categorised as a Read tool in the AGE-MCP-Server MCP Server, which means it retrieves data without modifying state.
Register the AGE-MCP-Server MCP server in PolicyLayer and add a rule for list-age-graphs: 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 AGE-MCP-Server. Nothing to install.
list-age-graphs 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 list-age-graphs 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 list-age-graphs. 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.
list-age-graphs is provided by the AGE-MCP-Server MCP server (rioriost/age_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
