# pipeworx `bls` — Bls

## Coverage
Bureau of Labor Statistics public data API (v2).

Catalog `tool_count`: 5. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/bls/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 41 tools: these 5 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `bls_get_series` — Fetch historical time series data for employment, inflation, wages, productivity, or housing. Required: `series_id`.
- `bls_search` — Search BLS economic data series by keyword. Required: `keyword`.
- `bls_latest` — Get the most recent data point for a BLS series. Required: `series_id`.
- `bls_popular_series` — Browse popular BLS series by category: employment, inflation, wages, housing, productivity. No required arguments.
- `bls_local_unemployment` — Look up the current LOCAL-AREA unemployment rate (or employment/labor force) for a US county, metro area (MSA), or city/town by NAME — e.g. "Wake County, NC", "Cary, North Carolina", "Fargo-Moorhead MSA". Required: `place`.

Client setup: `claude mcp add pipeworx-bls -- npx -y mcp-remote https://gateway.pipeworx.io/bls/mcp`.

## Auth
Catalog `auth.shape`: `platform-keyed`. Verbatim detail: "Pipeworx supplies the bls API key — no key needed from you. You may override it with `_apiKey`." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: measured 100% over 14 synthetic checks in 7d (last checked 2026-09-28).

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- Your own upstream key can be passed as `_apiKey`.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

History

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
