What hippo_export_graph does on Verimem
AI agents call hippo_export_graph to retrieve information from Verimem without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why hippo_export_graph is rated Low
The tool name 'hippo_export_graph' combined with the description 'memory as knowledge graph' indicates this tool reads and exports memory data in a graph format. Export operations are fundamentally read operations — they retrieve and serialize existing data without modifying it. Severity is medium because exporting a full knowledge graph could expose sensitive or private memory contents at scale.
From the tool's definition 'export_graph' and 'memory as knowledge graph' suggest data retrieval/export of stored memory
Attacks that exploit this kind of access
The rule that runs hippo_export_graph safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Verimem, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For hippo_export_graph, this is the rule to start with:
hippo_export_graph is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Verimem, apply this rule, and every hippo_export_graph call is checked against it from then on.
Questions about hippo_export_graph
FORGIA #326 — Round 43: memory as knowledge graph. It is categorised as a Read tool in the Verimem MCP Server, which means it retrieves data without modifying state.
Register the Verimem MCP server in PolicyLayer and add a rule for hippo_export_graph: 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 Verimem. Nothing to install.
hippo_export_graph 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 hippo_export_graph 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 hippo_export_graph. 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.
hippo_export_graph is provided by the Verimem MCP server (aureliocpr-ctrl/verimem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
