AI agents call list_pages to retrieve information from Nocobase 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 existing UI schema data from NocoBase without creating, modifying, deleting, or executing any operations. The emphasis on 'returns' and 'not page-level navigation' confirms it is a read-only query operation. The blast radius is minimal as it only exposes informational data that an AI agent could already access through other read operations.
From the tool's definition Tool name 'list_pages' and description 'List all UI schemas in NocoBase (returns raw schema nodes, not page-level navigation)' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
List all UI schemas in NocoBase (returns raw schema nodes, not page-level navigation). It is categorised as a Read tool in the Nocobase MCP Server, which means it retrieves data without modifying state.
Register the Nocobase MCP server in PolicyLayer and add a rule for list_pages: 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 Nocobase. Nothing to install.
list_pages 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 list_pages 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 list_pages. 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.
list_pages is provided by the Nocobase MCP server (puguhsudarma/nocobase-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
