Browse the knowledge graph structure. Returns the tree from a starting node (or root) with 3 levels of children. Use this to understand how knowledge is organized before searching or saving.
AI agents call browse_nodes 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 only retrieves and displays existing hierarchical structure from the knowledge graph. It has no capability to create, modify, delete, execute code, or affect financial systems. The blast radius of misuse is minimal—an agent could only view organized information that is already stored. This is a classic Read operation.
From the tool's definition Tool description states it 'Returns the tree from a starting node' and is used to 'understand how knowledge is organized.' The word 'browse' and 'returns' indicate read-only retrieval of structural information with no modification or side effects.

Browse the knowledge graph structure. Returns the tree from a starting node (or root) with 3 levels of children. Use this to understand how knowledge is organized before searching or saving. 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 browse_nodes: 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.
browse_nodes 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 browse_nodes 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 browse_nodes. 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.
browse_nodes 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.
