List task lists (kanban boards) in a workspace with their associated tasks, assignees, and reminders. Optionally filter to a specific task list by ID. Task list IDs are needed for create_task.
AI agents call list_task_lists 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 task lists, assignees, and reminders without creating, modifying, or deleting any data. It is purely informational and supports lookups needed for other operations (e.g., obtaining IDs for create_task). No destructive, financial, or executable actions are performed.
From the tool's definition Tool name 'list_task_lists' and description 'List task lists...in a workspace' indicates retrieval of existing data with no modification or side effects.

List task lists (kanban boards) in a workspace with their associated tasks, assignees, and reminders. Optionally filter to a specific task list by ID. Task list IDs are needed for create_task. 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_task_lists: 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_task_lists 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_task_lists 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_task_lists. 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_task_lists 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.
