List all folders in a Fusebase workspace as a nested tree structure. Each folder includes its children, icons, and sharing status. Use folder IDs to filter list_pages or as parentId when creating pages.
AI agents call list_folders to retrieve information from Fusebase MCP Server 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 the folder hierarchy structure without any side effects. It returns information about existing folders for navigation and reference purposes. There is no data creation, modification, deletion, code execution, or financial impact.
From the tool's definition Tool description states it 'List all folders in a Fusebase workspace' and 'Each folder includes its children, icons, and sharing status.' The verb 'list' and the read-only nature of retrieving folder structure with no modification capability.
Attacks that exploit this kind of access
List all folders in a Fusebase workspace as a nested tree structure. Each folder includes its children, icons, and sharing status. Use folder IDs to filter list_pages or as parentId when creating pages. It is categorised as a Read tool in the Fusebase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fusebase MCP Server MCP server in PolicyLayer and add a rule for list_folders: 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 Fusebase MCP Server. Nothing to install.
list_folders 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_folders 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_folders. 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_folders is provided by the Fusebase MCP Server MCP server (ryan-haver/fusebase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
