## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (6)

### `bls_get_series` (~214 tokens)

Fetch historical time series data for employment, inflation, wages, productivity, or housing. Returns dated data points with values. Provide a BLS series ID (e.g., "CES0000000001" for total nonfarm payroll employment, the headline Employment Situation jobs number; "LNS14000000" for the unemployment rate). "PAYEMS" is the FRED id for the same series, not a BLS id.

Input parameters:

- `_apiKey` (string): BLS registration key (optional, increases rate limits)
- `end_year` (string): End year (e.g., "2024"). Default: current year.
- `series_id` (string, required): BLS series ID (e.g., "LNS14000000" for unemployment rate). For multiple series, comma-separate them (e.g., "LNS14000000,CES0000000001").
- `start_year` (string): Start year (e.g., "2023"). Default: current year minus 2.

### `bls_search` (~70 tokens)

Search BLS economic data series by keyword. Returns matching series IDs and titles. Use bls_get_series with an ID to fetch historical data points.

Input parameters:

- `keyword` (string, required): Keyword to search for (e.g., "rent", "construction", "unemployment", "CPI", "housing")

### `bls_latest` (~74 tokens)

Get the most recent data point for a BLS series. Returns latest value and date. Use when you need current figures without historical context.

Input parameters:

- `_apiKey` (string): BLS registration key (optional)
- `series_id` (string, required): BLS series ID (e.g., "LNS14000000")

### `bls_popular_series` (~69 tokens)

Browse popular BLS series by category: employment, inflation, wages, housing, productivity. Returns series IDs and descriptions. Start here to explore available data.

Input parameters:

- `category` (string): Filter by category: housing, employment, prices, wages, productivity (optional, returns all if omitted)

### `bls_local_unemployment` (~328 tokens)

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". Resolves the place to its BLS LAUS series id (bls_get_series cannot do this; it needs a series ID, not a place name) and returns recent monthly data. Falls back to the county when a city is below the LAUS city-reporting threshold, and says so. Data is NOT seasonally adjusted.

Input parameters:

- `_apiKey` (string): BLS registration key (optional, increases rate limits)
- `measure` (string): One of: "rate" (unemployment rate, default), "unemployment" (level), "employment" (level), "labor_force" (level).
- `months` (number): How many most-recent monthly observations to return. Default 12.
- `place` (string, required): Place name: a county ("Wake County"), metro area ("Fargo-Moorhead MSA", "Raleigh-Cary MSA"), or city/town ("Cary"). Include "County" or "MSA"/"Metro" in the name to disambiguate the kind when it matt…
- `state` (string): US state, 2-letter code or full name (e.g. "NC" or "North Carolina"). Optional if already included in `place` (e.g. "Cary, NC").

### `bls_occupation_projections` (~320 tokens)

Official US Employment Projections by occupation (SOC code): projected 10-year employment growth (number and percent), annual average job openings, current employment, median annual wage, and typical entry education, experience and training, from the Bureau of Labor Statistics, Employment Projections program. Look up an occupation by SOC code ("15-1252") or title words ("software developers"), or rank all detailed occupations by growth, openings or wage. Answers "projected growth for registered nurses", "which occupations have the most annual openings", "fastest growing jobs". Employment and openings are in thousands. Always reports the projection vintage (base and target year) of the latest release.

Input parameters:

- `direction` (string): With rank_by or a query list: highest (default) or lowest first, e.g. fastest declining.
- `limit` (number): Max occupations returned (default 10, max 50).
- `min_employment_thousands` (number): For rankings: ignore occupations employing fewer than this many thousand workers (default 0).
- `query` (string): Words from the occupation title, e.g. "nurse practitioners". Matches every word.
- `rank_by` (string): Instead of a lookup, rank detailed occupations by this measure, highest first (default listing when neither soc_code nor query is given: openings).
- `soc_code` (string): SOC code, e.g. "15-1252" (detailed), "15-1200" or "15-0000" (summary/major group).
