Get detailed information about a specific node including its children and all resources. Use this to inspect what
AI agents call get_node to retrieve information from Idea Basin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries information from a knowledge graph without creating, modifying, deleting, or executing any operations. It is a standard read operation that inspects node details and associated resources, posing minimal security risk.
From the tool's definition Tool name 'get_node' and description 'Get detailed information about a specific node including its children and all resources. Use this to inspect' indicates retrieval and inspection of data with no modification or execution capabilities.
Attacks that exploit this kind of access
Get detailed information about a specific node including its children and all resources. Use this to inspect what. It is categorised as a Read tool in the Idea Basin MCP Server, which means it retrieves data without modifying state.
Register the Idea Basin MCP server in PolicyLayer and add a rule for 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 Idea Basin. Nothing to install.
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 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 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.
get_node is provided by the Idea Basin MCP server (msfixer101/idea-basin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
