US labor-market turnover from BLS JOLTS (total nonfarm, national), monthly newest-first. measure = openings (default) / hires / quits / layoffs / separations. Returns level in thousands per month. The standard labor-tightness (openings) + worker-confidence (quits) signal. Public-domain.
AI agents call labor.openings to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns pre-computed labor statistics from the Bureau of Labor Statistics (BLS JOLTS database). There are no modifications to data, no code execution, no deletions, and no financial transactions. The measure parameter simply filters what metric is returned, not what data is modified. The data is explicitly stated as public-domain.
From the tool's definition Tool returns US labor-market data from BLS JOLTS: 'monthly newest-first', 'Returns level in thousands per month'. The measure parameter allows selection of 'openings (default) / hires / quits / layoffs / separations'.

US labor-market turnover from BLS JOLTS (total nonfarm, national), monthly newest-first. measure = openings (default) / hires / quits / layoffs / separations. Returns level in thousands per month. The standard labor-tightness (openings) + worker-confidence (quits) signal. Public-domain. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for labor.openings: 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 Mcp. Nothing to install.
labor.openings 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 labor.openings 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 labor.openings. 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.
labor.openings is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
