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 →
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 4 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 Usability79
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1542 tokens (~220/item across 7 items; 4 tools + 3 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 Management27
- Stability observed for 8 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

cdc_query_dataset Cdc Query Dataset ~403

| select | string | — | SoQL SELECT clause — column names, aliases, or aggregates: "state, sum(deaths) as total_deaths". Omit for all columns. To enumerate distinct values of a column, set select to "{column}, count(*) as c… |
| where | string | — | SoQL WHERE clause. Strings must be single-quoted: "state='California' AND year=2020". If a column name matches a SoQL keyword (group, select, where, order, limit, offset, having, search), wrap it in… |

No examples provided.
cdc_query_wonder Cdc Query Wonder ~348
Query CDC WONDER for national US mortality statistics — deaths, population, and crude/age-adjusted death rates — from the Underlying Cause of Death database (D76, 1999–2020). Break results out by year, age group, sex, and/or race, and filter by ICD-10 cause of death, sex, age group, or year range. WONDER is a separate CDC system from the Socrata datasets the other cdc_* tools query. Data is national only — sub-national (state/county) breakdowns are not available through the API (CDC vital-statistics policy). Cause of death is a filter, not a grouping. CDC suppresses any cell with fewer than 10 deaths (returned as null). The API is rate-limited to one request every ~15 seconds, so requests may be briefly spaced.
| Name | Type | Req | Description |
|---|---|---|---|
| age_groups | array | — | Restrict to specific ten-year age groups — e.g. ["25-34","35-44"]. "1" is the under-1-year group. Omit for all ages. |
| cause_icd10 | — | — | Filter to a specific ICD-10 underlying cause of death. Omit for all causes. |
| group_by | array | — | Dimensions to break results out by (1–4), in output-column order — e.g. ["year"], ["year","sex"], ["age_group","race"]. Results are always national. Cause of death is a filter (cause_icd10), not a gr… |
| sex | string | — | Filter by sex. |
| year_range | object | — | Inclusive year range within 1999–2020. Omit for all years. |
| Name | Type | Req | Description |
|---|---|---|---|
| caveats | array | yes | CDC-provided caveats and footnotes: data revisions, population-estimate sources, suppression and rate-reliability rules. |
| database | string | yes | WONDER database queried (D76 — Underlying Cause of Death, 1999–2020). |
| effectiveQuery | string | yes | Human-readable summary of the grouping and filters sent to WONDER. |
| notice | string | — | Guidance when no rows matched, or a note that CDC suppressed some cells. |
| rowCount | number | yes | Number of rows returned. |
| rows | array | yes | Result rows. Each carries the requested group-by dimensions plus deaths, population, crude_rate, and — unless grouped by age_group — age_adjusted_rate (per 100,000). Suppressed measure cells (< 10 de… |
| suppressedCount | number | yes | Number of measure cells CDC suppressed (< 10 deaths), returned as null. |
