Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1827 tokens (~304/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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.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 current MCP spec version (2026-07-28).Pass
How do I install the io.github.cyanheads/bls-labor-mcp-server server?
io.github.cyanheads/bls-labor-mcp-server is a hosted endpoint at https://bls-labor.caseyjhand.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

bls_dataframe_describe Describe BLS Dataframes ~99
List canvas dataframes materialized by bls_get_series, with provenance (source tool, query parameters), TTL, row count, and column schema. Use before writing SQL to confirm column names. Lazy-sweeps expired tables before responding. Requires CANVAS_PROVIDER_TYPE=duckdb.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | – | Optional table name (df_XXXXX_XXXXX) to describe a single dataframe. Omit to list all active dataframes. |
| Name | Type | Req | Description |
|---|---|---|---|
| dataframes | array | – | Active dataframes for this tenant, newest first. |
| error | object | – | Present when the call failed. Absent on success. |
No examples provided.
bls_dataframe_query Query BLS Dataframes ~354
Run a single-statement SELECT against the canvas dataframes registered by bls_get_series. Read-only: writes, DDL, DROP, COPY, PRAGMA, ATTACH, and external-file table functions are rejected. System catalogs (information_schema, pg_catalog, sqlite_master, duckdb_*) are denied at the bridge layer — use bls_dataframe_describe to list available dataframes. Supports JOINs, aggregates, window functions, and CTEs. Optional register_as persists the result as a new dataframe with a fresh TTL for chained analysis. Canvas SQL operations consume zero BLS API quota. Requires CANVAS_PROVIDER_TYPE=duckdb.
| Name | Type | Req | Description |
|---|---|---|---|
| preview | integer | – | Inline row preview count. Defaults to row_limit. Set lower (e.g. 50) when chaining via register_as and only a sample is needed immediately. |
| register_as | string | – | When set, persist the query result as a new dataframe under this name. Fresh TTL — not inherited from parent tables. Use to chain analyses without re-running source SQL or consuming additional BLS qu… |
| row_limit | integer | – | Hard cap on rows materialized in the response (default 1000, max 10000). Full results live on-canvas under register_as when provided. |
| sql | string | yes | Single-statement SELECT against df_<id> tables on the shared canvas. Reference dataframes by the names returned in bls_get_series responses or listed by bls_dataframe_describe. Standard DuckDB SQL —… |
| Name | Type | Req | Description |
|---|---|---|---|
| cap | number | – | The preview or row_limit cap that was applied. |
| columns | array | – | Column names in projection order. |
| error | object | – | Present when the call failed. Absent on success. |
| expires_at | string | – | ISO 8601 expiry for the newly registered dataframe, when applicable. |
| notice | string | – | Guidance when results were capped by preview or row_limit — names which parameter was the binding limiter and suggests how to retrieve the rest. Absent when all rows fit in the response. |
| registered_as | string | – | Set when register_as was supplied and the result was materialized. |
| row_count | number | – | Rows materialized by the query. Exact when register_as is used; otherwise equals row_limit when truncated is true. |
| rows | array | – | Materialized rows, bounded by preview / row_limit. |
| shown | number | – | Number of rows returned inline. |
| truncated | boolean | – | True when the returned rows were capped. |
No examples provided.
bls_get_latest Get Latest BLS Observation ~148
Return the single most recent observation for one or more BLS series. Use for "what is X right now" questions — the current unemployment rate, the latest CPI reading, etc. Each series consumes one API query against the 500/day limit; for the current value of many series, bls_get_series with a 1-year window is more quota-efficient (one query for up to 50 series). Recommended limit: 10 series; maximum: 50.
| Name | Type | Req | Description |
|---|---|---|---|
| series_ids | array | yes | One or more BLS SeriesIDs (1–50). Each consumes one daily API query. Use bls_search_series to resolve concepts to SeriesIDs. Recommended: ≤10 series. |
| Name | Type | Req | Description |
|---|---|---|---|
| error | object | – | Present when the call failed. Absent on success. |
| failed | array | – | Series that failed to fetch. Inspect seriesId and error for per-item details. Not-found series appear here rather than as a tool-level error. |
| notice | string | – | Guidance when one or more series failed — e.g. to use bls_search_series to verify SeriesIDs. Absent when all series returned data. |
| results | array | – | Successfully fetched series with their latest observations. Series that failed appear in failed[] instead. |
| succeeded | number | – | Number of series with a successfully fetched observation. |
No examples provided.
bls_get_series Get BLS Time-Series Data ~661
Fetch time-series data for 1–50 BLS series by SeriesID in a single API request (one query against the 500/day limit). Supports optional year range (up to 20 years per request) and BLS-computed period-over-period calculations (net change and percent change; a survey returns whichever it supports and silently omits the rest — CPI and PPI return percent change only, the inflation rate). BLS can publish a '-' missing-value sentinel; check observation.available before arithmetic. Set annual_average to add each year's annual-average row, which is that year's mean rather than an additional period. When the total observation count would exceed the inline context budget, results spill to a canvas dataframe and the response includes a dataset.name handle. Call bls_dataframe_describe with that name to inspect the dataframe schema, then use the name in bls_dataframe_query SQL. Use bls_search_series first if you need to resolve a concept to a SeriesID.
| Name | Type | Req | Description |
|---|---|---|---|
| annual_average | boolean | – | When true, add each year's annual-average row to the observations. An annual average is the mean of that year's real periods, returned as an extra row named "Annual" with period M13 (monthly series),… |
| calculations | boolean | – | When true, request BLS-computed period-over-period calculations. The flag is a single boolean (you cannot select an individual calculation type), but the API returns whichever the survey supports and… |
| end_year | integer | – | End year for the data range (inclusive). Supplying it without start_year is rejected before the request — BLS applies no default start year alongside an explicit end year. Pair it with start_year, or… |
| series_ids | array | yes | One or more BLS SeriesIDs (1–50). The entire batch counts as one API query. Use bls_search_series to resolve concepts to SeriesIDs. |
| start_year | integer | – | Start year for the data range (inclusive). The BLS API allows up to 20 years per request and requires both bounds or neither: supplying start_year alone resolves end_year to the current year, capped… |
| Name | Type | Req | Description |
|---|---|---|---|
| annualAverageApplied | boolean | – | Whether annual-average rows were requested. When false, observations hold real periods only; filter on available before aggregation. |
| annualAverageRows | number | – | How many observations across all series are annual-average rows (period M13/Q05/S03). Present only when annual_average is true; 0 means none of the requested surveys publish annual averages. |
| availableObservations | number | – | Rows with a published numeric value. |
| calculationsApplied | boolean | – | Whether BLS net/percent-change calculations were requested. |
| dataset | object | – | Canvas dataframe handle — present when the observation volume exceeded the inline budget. Call bls_dataframe_describe with dataset.name to inspect column_schema, then use that table name in bls_dataf… |
| endYearApplied | number | – | End year applied to the query. Resolved from start_year when end_year was omitted, so it can differ from the requested range; notice names the cap when the 20-year window decided it. Absent when no y… |
| error | object | – | Present when the call failed. Absent on success. |
| notice | string | – | Guidance for agents — names any SeriesID that returned zero observations, reports a resolved end_year the 20-year window capped, and reports the bls_dataframe_describe then bls_dataframe_query workfl… |
| series | array | – | Series data, in request order. |
| seriesRequested | number | – | Number of SeriesIDs requested. Do not compare it against series[] length to find empty series — a SeriesID that returned no data is still listed in series[] with observationCount 0. Check observation… |
| spilled | boolean | – | True when results spilled to canvas due to inline budget overflow. |
| startYearApplied | number | – | Start year applied to the query, whether it was served live or from the local observation mirror. Absent when no year range was in effect. |
| totalObservations | number | – | Total observation rows across all requested series. |
| unavailableObservations | number | – | Rows carrying the BLS "-" missing-value sentinel. |
No examples provided.
bls_list_surveys List BLS Surveys ~103
List BLS survey programs with their abbreviation codes, full names, and metadata about calculation support and annual averages. Use to discover which survey covers a topic before calling bls_search_series. Optional category filter narrows results to prices, employment, wages, productivity, injuries, or time_use surveys.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter. One of: prices, employment, wages, productivity, injuries, time_use. Omit to list all surveys. |
| Name | Type | Req | Description |
|---|---|---|---|
| categoryFilter | string | – | Category filter applied, if any. Absent when all surveys were listed. |
| error | object | – | Present when the call failed. Absent on success. |
| surveys | array | – | BLS survey programs matching the filter, sorted alphabetically by abbreviation. |
| total | number | – | Total surveys returned. |
No examples provided.
bls_search_series Search BLS Series ~309
Search the BLS series catalog by natural language query, survey code, geographic area, or keywords to resolve cryptic SeriesIDs. Returns matching series with decoded components (survey, area, item, seasonal flag) and plain-language names. Use this before bls_get_series when you have a concept but not a SeriesID. Operates offline — no API quota consumed. Survey filter accepts two-letter codes (CU, CE, LN, LA, PC, JT, OE, EC, PR). Area filter accepts state names, MSA names, or FIPS area codes.
| Name | Type | Req | Description |
|---|---|---|---|
| area | string | – | State name, MSA name, or FIPS area code to narrow results to a geographic area. Omit for national series. |
| limit | integer | – | Maximum number of results to return (1–50, default 10). |
| query | string | yes | Natural language or keyword query (e.g. "unemployment rate", "CPI food", "nonfarm payrolls"). Also accepts a SeriesID directly for exact lookup. |
| seasonal_adjustment | boolean | – | When true, return only seasonally adjusted series. When false, return only not-seasonally-adjusted. Omit to return both. |
| survey | string | – | Two-letter LABSTAT survey abbreviation to filter results (e.g. CU for CPI, CE for CES, LN for CPS, LA for LAUS, JT for JOLTS, OE for OEWS). Omit to search all loaded surveys. |
| Name | Type | Req | Description |
|---|---|---|---|
| areaFilter | string | – | Area filter applied, if any. Absent when no area filter was passed. |
| cap | number | – | The result limit that capped the returned list. |
| capped | boolean | – | True when the FTS candidate pool reached the internal cap (~1000). totalCount is then a lower bound, not an exact match count. Narrow the query, add survey/area filters, or use a direct SeriesID to g… |
| catalogSize | number | – | Total series in the loaded catalog index. Distinguishes an empty-result search from a failed catalog load. |
| effectiveQuery | string | – | Query string as the server received and searched on. Confirms interpretation for self-correction. |
| error | object | – | Present when the call failed. Absent on success. |
| limitApplied | number | – | Result limit in effect (defaults to 10 when omitted). |
| notice | string | – | Guidance when no results matched — e.g. how to broaden the query or remove filters. Absent when results are returned. |
| seasonalFilter | boolean | – | Seasonal-adjustment filter applied, if any. Absent when not passed. |
| series | array | – | Matching series, ordered by relevance. |
| shown | number | – | Number of series returned in this response. |
| surveyFilter | string | – | Survey filter applied, if any. Absent when no survey filter was passed. |
| totalCount | number | – | Total candidates scored before the limit was applied. A lower bound when capped is true — the catalog index may contain more matching series. |
| truncated | boolean | – | True when more candidates matched than the limit returned. |
