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 Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 961 tokens (~160/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
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 6 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
How do I install the American Default Research MCP server?
American Default Research is a hosted endpoint at https://mcp.americandefault.org/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.

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 →
get_adi_composite ~96
Fetch the latest quarterly reading of the American Distress Index (ADI) composite. Returns the composite score (0-100), band (1-5) with its label and the literal reading gloss, the composite's own rank in history, and the five-domain breakdown (Delinquency, Default & Legal, Debt Burden, Labor, Safety Net & Buffer) with domain scores and member component percentiles. Updated quarterly.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_county_scorecard ~159
Fetch a county's County Distress Index (CDI) scorecard by 5-digit FIPS code. Returns composite score (0-100), score label, national + state rank, 5-domain breakdown (Delinquency, Default & Legal, Debt Burden, Labor, Safety Net & Buffer), key findings, and pre-baked APA / MLA / Chicago / news-copy citations. Accepts 4-digit FIPS with implicit leading zero. 3,144 counties available.
| Name | Type | Req | Description |
|---|---|---|---|
| fips | string | yes | The 5-digit numeric county FIPS code as a string (e.g., '13063' for Clayton County, GA). 4-digit values are zero-padded internally. 3,144 counties available. |
No output schema declared.
No examples provided.
get_cross_correlations ~189
Fetch statistically-validated leading/lagging relationships for an indicator. Source: the five-filter leading-indicator scanner (cross-correlation → first-differenced CCF → multi-crisis validation → Granger causality → out-of-sample validation). Returns two lists: `as_leader` (pairs where this indicator precedes its follower) and `as_follower` (pairs where another indicator precedes this one). Only fully-validated pairs are included — partial matches are not surfaced. Most of the 103 indicators return empty lists; only a handful of pairs clear the full gauntlet.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | The kebab-case indicator slug to look up (e.g., 'the-buffer', 'initial-unemployment-claims-sa'). Returns split lists of pairs where this indicator is the leader vs the follower. Empty lists are commo… |
No output schema declared.
No examples provided.
get_indicator ~180
Fetch a compact snapshot of an American Default economic indicator by slug. Returns latest value, unit, frequency, direction, pre-computed aggregates (period averages, extremes, sustained runs), editorial prose (when available), and canonical APA / MLA / Chicago / news-copy citations. Raw historical series is NOT included — use https://americandefault.org/api/indicators/{slug}.json for the full data. Slug examples: 'the-buffer' (personal savings rate), 'mortgage-delinquency', 'initial-unemployment-claims-sa'.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | The kebab-case indicator slug (e.g., 'the-buffer' for personal savings rate, 'mortgage-delinquency', 'initial-unemployment-claims-sa'). 103 indicators available. Use `search_indicators` first to disc… |
No output schema declared.
No examples provided.
get_indicator_v2 ~139
Fetch an explicitly versioned compact indicator snapshot. Returns the latest value and canonical citation plus `trend_suppressed` and `series_breaks` comparison-safety fields. Callers must pass `response_version='v2'`; unsupported versions fail closed. The legacy `get_indicator` tool remains pinned to its original v1 shape.
| Name | Type | Req | Description |
|---|---|---|---|
| response_version | string | yes | Required explicit response contract version. The only supported value for this tool is 'v2'. |
| slug | string | yes | The kebab-case indicator slug (e.g., 'the-buffer' or 'the-pinch'). Use `search_indicators` to discover slugs. |
No output schema declared.
No examples provided.
search_indicators ~198
Search the 103-indicator registry by keyword. Returns ranked matches (up to `limit`, default 10, max 50) with slug, branded name, underlying name, category, and canonical URL. Scoring is substring+prefix over slug, branded_name, name, and category — e.g. query 'savings' returns both The Buffer (personal saving rate) and The Safety Net (emergency savings survey). Use this when you want to discover which slug corresponds to a concept before calling `get_indicator`.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Max number of ranked matches to return. Default 10. Hard cap 50 (values above are clamped). Values above 1000 are rejected as abuse. |
| query | string | yes | The keyword to search (e.g., 'savings', 'mortgage', 'inflation'). Scoring runs substring + prefix matching over slug, branded_name, name, and category fields. |
No output schema declared.
