How do I find my BLS Registration Key?

Register for an account at the [**BLS developer portal**](https://data.bls.gov/registrationEngine/), and you will receive your Registration Key via email. Copy and paste it below.

A series ID is a unique code identifying a specific statistical dataset, such as 'CUUR0000SA0' for the Consumer Price Index.

Can I query multiple series at once?

Yes. The `get_bls_timeseries_data` tool accepts an array of series IDs to retrieve metadata for multiple datasets in a single request.

About BLS Public Data API MCP Server

Empower your AI agent to orchestrate your entire economic research and labor auditing workflow with the BLS Public Data API, the authoritative source for United States Bureau of Labor Statistics data. By connecting the BLS API to your agent, you transform complex macroeconomic searches into a natural conversation. Your agent can instantly retrieve historical time series data, audit employment trends, and query specific series IDs without you ever touching a government portal. Whether you are conducting market research or managing regional economic constraints, your agent acts as a real-time data analyst, ensuring your intelligence is always verified and precise.

Cursor's Agent mode turns BLS Public Data API into an in-editor superpower. Ask Cursor to generate code using live data from BLS Public Data API and it fetches, processes, and writes. all in a single agentic loop. 2 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

What you can do

Series Auditing — Retrieve high-resolution time series data for thousands of BLS identifiers and maintain a clear view of economic changes.
Trend Oversight — Audit historical labor statistics to understand the longitudinal distribution of economic scale instantly.
Economic Discovery — Query specific series IDs like the Consumer Price Index (CPI) to identify relevant fiscal markers for your research.
Metadata Intelligence — Retrieve unique series identifiers and year-based metadata to assist in deep-dive data classification.
Operational Monitoring — Check API status to ensure your economic research workflow is always operational.

The BLS Public Data API MCP Server exposes 2 tools through the Vinkius. Connect it to Cursor in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

BLS Public Data API + Cursor FAQ

Common questions about integrating BLS Public Data API MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
