Get a node with its relations and child nodes.
AI agents call graph_get_node to retrieve information from MCP Roo Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves graph node information and its relationships without creating, modifying, or deleting any data. The use of 'Get' clearly indicates a read-only operation with no side effects. The blast radius of misuse is minimal—an agent could only access information already stored in the graph, not alter or destroy it.
From the tool's definition Tool name 'graph_get_node' and description 'Get a node with its relations and child nodes' indicate retrieval of existing data with no modification or deletion.
Attacks that exploit this kind of access
Get a node with its relations and child nodes. It is categorised as a Read tool in the MCP Roo Memory MCP Server, which means it retrieves data without modifying state.
Register the MCP Roo Memory MCP server in PolicyLayer and add a rule for graph_get_node: 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 Roo Memory. Nothing to install.
graph_get_node 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 graph_get_node 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 graph_get_node. 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.
graph_get_node is provided by the MCP Roo Memory MCP server (mcasdfgf/mcp-roo-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
