List all workspaces in your Fusebase organization with their IDs, titles, and colors. Use this first to discover workspace IDs needed by most other tools.
AI agents call list_workspaces 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 organizational data without modifying, deleting, or executing any operations. It is a discovery/lookup function that serves as a prerequisite for other tools but causes no changes to the system state. The low severity reflects minimal blast radius if misused by an AI agent—only information exposure.
From the tool's definition Tool name is 'list_workspaces' and description states it 'List all workspaces' - a pure retrieval operation with no side effects. Returns read-only information: workspace IDs, titles, and colors.
Attacks that exploit this kind of access
List all workspaces in your Fusebase organization with their IDs, titles, and colors. Use this first to discover workspace IDs needed by most other tools. 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_workspaces: 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_workspaces 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_workspaces 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_workspaces. 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_workspaces 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.
list_workspaces is one line of Fusebase MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
