What neuron_list_knowledge_bases does on Neuron
AI agents call neuron_list_knowledge_bases to retrieve information from Neuron without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why neuron_list_knowledge_bases is rated Low
This tool retrieves and enumerates knowledge bases accessible to the user. It performs a read-only query with no ability to modify, delete, or execute operations. The blast radius of misuse is minimal: an attacker gains visibility into what knowledge bases exist but cannot access their contents or modify them without additional tools. Low severity is appropriate for information disclosure of object inventories.
From the tool's definition Tool name contains 'list' and description states 'Retrieve all knowledge bases' — a query operation with no side effects.
Attacks that exploit this kind of access
The rule that runs neuron_list_knowledge_bases safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Neuron, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For neuron_list_knowledge_bases, this is the rule to start with:
neuron_list_knowledge_bases 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 Neuron, apply this rule, and every neuron_list_knowledge_bases call is checked against it from then on.
Questions about neuron_list_knowledge_bases
Retrieve all knowledge bases accessible to the current user. It is categorised as a Read tool in the Neuron MCP Server, which means it retrieves data without modifying state.
Register the Neuron MCP server in PolicyLayer and add a rule for neuron_list_knowledge_bases: 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 Neuron. Nothing to install.
neuron_list_knowledge_bases 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 neuron_list_knowledge_bases 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 neuron_list_knowledge_bases. 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.
neuron_list_knowledge_bases is provided by the Neuron MCP server (neuron-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
