List pages (notes) in a Fusebase workspace with titles, types, and metadata. Supports pagination and filtering by folder. Returns compact summaries — use get_page for full details on a specific page.
AI agents call list_pages 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 queries and retrieves page information from a Fusebase workspace without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with no side effects. Severity is low because listing metadata poses minimal risk — the worst case is information disclosure, and the blast radius of accidental misuse is limited to exposing workspace structure and page summaries.
From the tool's definition Tool description states it 'List pages' and 'Returns compact summaries'. The verb 'list' and the explicit statement that it retrieves page titles, types, and metadata with no mention of modification, deletion, or execution indicate a retrieval operation.

List pages (notes) in a Fusebase workspace with titles, types, and metadata. Supports pagination and filtering by folder. Returns compact summaries — use get_page for full details on a specific page. 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_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 Fusebase MCP Server. 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 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.
