AI agents call teams_workspace_read 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 file content from a workspace directory without side effects, matching the definition of Read category. Severity is low because it only accesses existing data without ability to modify, execute, or delete. Confidence is high due to explicit 'Read' language and clear retrieval-only semantics.
From the tool's definition Tool name includes 'read' and description states 'Read a text file from the workspace directory' — a pure retrieval operation with no modification or execution.
Attacks that exploit this kind of access
Read a text file from the 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_read: 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_read 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_read 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_read. 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_read 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.
