List all Fabric workspaces the caller has access to.
AI agents call list_workspaces to retrieve information from Fabric Dw Mcp Cli without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to enumerate workspaces accessible to the caller. It retrieves information but does not create, modify, delete, or execute any operations. The blast radius of misuse is limited to potential information disclosure about workspace names and access, which is low severity.
From the tool's definition Tool name 'list_workspaces' and description 'List all Fabric workspaces the caller has access to' indicate a query operation that retrieves data without side effects.
Attacks that exploit this kind of access
List all Fabric workspaces the caller has access to. It is categorised as a Read tool in the Fabric Dw Mcp Cli MCP Server, which means it retrieves data without modifying state.
Register the Fabric Dw Mcp Cli 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 Fabric Dw Mcp Cli. 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 Fabric Dw Mcp Cli MCP server (sdebruyn/fabric-dw-mcp-cli). 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 Fabric Dw Mcp Cli's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
