Category Data and Analytics
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. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-bls). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 5 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1127 tokens (~187/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 5 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
bls_get_series ~214
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.
| Name | Type | Req | Description |
|---|---|---|---|
| _apiKey | string | – | BLS registration key (optional, increases rate limits) |
| end_year | string | – | End year (e.g., "2024"). Default: current year. |
| series_id | string | yes | 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_latest ~74
Get the most recent data point for a BLS series. Returns latest value and date. Use when you need current figures without historical context.
| Name | Type | Req | Description |
|---|---|---|---|
| _apiKey | string | – | BLS registration key (optional) |
| series_id | string | yes | BLS series ID (e.g., "LNS14000000") |
No output schema declared.
No examples provided.
bls_local_unemployment ~328
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.
| Name | Type | Req | Description |
|---|---|---|---|
| _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 | yes | 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"). |
No output schema declared.
No examples provided.
bls_occupation_projections ~320
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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). |
