AI agents call teams_workspace_list to retrieve information from Outpost without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information about files in a workspace directory without creating, modifying, deleting, or executing anything. It is a standard read operation with minimal blast radius if misused by an agent (e.g., exposing file names/structure that may contain sensitive metadata, but not altering system state).
From the tool's definition Tool description states 'List files currently in the transient workspace directory' — the verb 'List' and the read-only nature of querying a directory's contents indicate data retrieval with no side effects.
Attacks that exploit this kind of access
List files currently in the transient workspace directory. It is categorised as a Read tool in the Outpost MCP Server, which means it retrieves data without modifying state.
Register the Outpost MCP server in PolicyLayer and add a rule for teams_workspace_list: 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 Outpost. Nothing to install.
teams_workspace_list 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 teams_workspace_list 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 teams_workspace_list. 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.
teams_workspace_list is provided by the Outpost MCP server (signalclaude/outpost). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
