What ruvector-gnn does on Ruflo
AI agents invoke ruvector-gnn to trigger actions in Ruflo. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why ruvector-gnn is rated High
This tool executes graph neural network operations on provided data. While it does not directly run arbitrary shell commands or modify persistent state, it performs computational execution whose output depends on input arguments and model parameters.
From the tool's definition Tool description states 'Execute GNN layer' with specific neural network architectures (GCN, GAT, GraphSAGE, GIN, MPNN, EdgeConv). The verb 'Execute' directly indicates code/computation execution.
Attacks that exploit this kind of access
The rule that runs ruvector-gnn safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ruflo, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ruvector-gnn, this is the rule to start with:
ruvector-gnn stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ruflo, apply this rule, and every ruvector-gnn call is checked against it from then on.
Questions about ruvector-gnn
Execute GNN layer (GCN, GAT, GraphSAGE, GIN, MPNN, EdgeConv). It is categorised as a Execute tool in the Ruflo MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Ruflo MCP server in PolicyLayer and add a rule for ruvector-gnn: 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 Ruflo. Nothing to install.
ruvector-gnn is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ruvector-gnn 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 ruvector-gnn. 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.
ruvector-gnn is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
