Retrieve the current value of the WORK_DIR environment variable.
AI agents call send_work_dir to retrieve information from Vibe Preprocessing and Analysis MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns an environment variable value (WORK_DIR), producing no side effects. It is a simple read/query operation. Severity is low as it exposes a directory path but no sensitive credentials or data directly.
From the tool's definition Retrieve the current value of the WORK_DIR environment variable.
Attacks that exploit this kind of access
Retrieve the current value of the WORK_DIR environment variable. It is categorised as a Read tool in the Vibe Preprocessing and Analysis MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Vibe Preprocessing and Analysis MCP Server MCP server in PolicyLayer and add a rule for send_work_dir: 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 Vibe Preprocessing and Analysis MCP Server. Nothing to install.
send_work_dir 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 send_work_dir 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 send_work_dir. 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.
send_work_dir is provided by the Vibe Preprocessing and Analysis MCP Server MCP server (mudit14224/vibe-data-analysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
