List configured workspaces.
AI agents call knowledge_list_workspaces to retrieve information from Chisel Knowledge MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that enumerates configured workspaces. It has no side effects, creates no data, executes no code, and destroys nothing. The blast radius of misuse is minimal—an agent could discover workspace names but cannot manipulate them. Classified as Read with low severity.
From the tool's definition Tool name 'knowledge_list_workspaces' and description 'List configured workspaces' indicate a query/list operation that retrieves information about existing workspaces without modifying, deleting, or executing any operations.
Attacks that exploit this kind of access
List configured workspaces. It is categorised as a Read tool in the Chisel Knowledge MCP MCP Server, which means it retrieves data without modifying state.
Register the Chisel Knowledge MCP server in PolicyLayer and add a rule for knowledge_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 Chisel Knowledge MCP. Nothing to install.
knowledge_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 knowledge_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 knowledge_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.
knowledge_list_workspaces is provided by the Chisel Knowledge MCP server (teknologika/chisel-knowledge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
