## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 4679 tokens (~425/item across 11 items; 10 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### `fdic_query_financials` (~586 tokens)

Query a multi-bank financial panel

Pull a multi-institution, multi-quarter Call Report panel — one row per institution per quarter — filtered by CERTs, headquarters state, asset range, and thresholds on any catalog metric. Use it to screen (every bank in a state with a noncurrent-loan rate above 3%) or to build a trend panel for SQL. Returns one page of the panel sorted as requested, continued with offset; at offset 0 a panel larger than the page is also staged as a dataframe for fdic_dataframe_query. With no dates it covers the latest published quarter only.

Input parameters:

- `certs` (array): Nonempty selection, at most 1000 raw CERTs. Deduplicated before querying the first 100; deferred_certs holds the rest for another call. Omit to screen every filer.

- `min_assets` (number): Minimum total assets in that quarter, thousands of US dollars (1000000 = $1 billion); applied to each quarter's report.
- `offset` (integer): Fetched panel rows to skip; pass next_offset from the previous page. Only offset 0 stages a dataframe.
- `sort_by` (string): Metric to order the pages (and the staged table) by; added to metrics when absent. Omit to order by newest quarter, then CERT.
- `sort_order` (string): desc (default, largest first) or asc; applies to sort_by. Rows without a value sort last.
- `state` (string): Headquarters state: two-letter code in any case or full name. Branch locations are in fdic_get_deposits.
- `to_date` (string): Latest quarter, in the same forms as from_date. Omit for the latest published quarter; beside from_date, a later quarter is cut back to it.

Output parameters:

- `panel_row_cap` (integer): This server's row cap for one panel.
- `panel_truncated` (boolean): True when total_matching exceeded the panel row cap. Whole quarters are kept newest first, so a truncated panel is missing its oldest quarters — or, when the newest quarter alone exceeds the cap, the…
- `processed_certs` (array): Deduplicated CERT selection actually queried; missing CERTs are a subset of these.
- `processed_metrics` (array): Metrics actually queried, including automatic panel sort/filter metrics.
- `report_dates` (object): Quarter range as applied.

### `fdic_get_deposits` (~530 tokens)

Get Summary of Deposits branches and market share

Get Summary of Deposits data (branch-level domestic deposits, annual as of June 30, 1994 onward). With cert only: the institution's branches and its deposit market share in each state where it has offices. With a geography (state, county, city, ZIP, or MSA code): every institution in that market ranked by deposits, with market share and the Herfindahl-Hirschman index. With both: the institution's branches in that market and its rank and share there. Branches and rankings come a page at a time, continued with offset; at offset 0 a set larger than the page is also staged as a dataframe for fdic_dataframe_query. Defaults to the latest survey year. Dollar amounts are in thousands.

Input parameters:

- `cert` (integer): FDIC certificate number, from fdic_search_institutions. Alone: its branches and per-state share. With a geography: its position in that market.
- `city` (string): Branch city as FDIC spells it (Seattle, St. Louis), up to 50 characters; matched exactly as given or in title case, with a hyphen, apostrophe, or space between words also tried the other ways FDIC re…
- `county` (string): County as FDIC spells it (King, not King County — a trailing " County" is stripped), up to 50 characters; matched exactly as given or in title case, with a hyphen, apostrophe, or space between words…
- `limit` (integer): Positive count of rows per page, sliced from the already-fetched branches or ranking at offset. At offset 0 a larger set is also staged whole as a dataframe when this deployment stages dataframes.
- `msa_code` (string): Five-digit CBSA (metropolitan area) code, 10180–49740; branch rows (returned when cert is given) carry msa_code values to reuse. Non-metropolitan branches have no code.
- `offset` (integer): Branches or ranked institutions to skip; pass next_offset from the previous page. Only offset 0 stages a dataframe.
- `state` (string): Branch state: two-letter code in any case or full name.
- `year` (integer): Survey year (deposits as of June 30), 1994 on. Omit for the latest survey.
- `zip` (string): Five-digit branch ZIP code; leading zeros kept (02110).

Output parameters:

- `branches` (array): Institution modes: one page of the branches in scope by branch number (main office first), starting at offset.
- `cap` (number): The limit applied to this page.
- `data_as_of` (string): When FDIC last rebuilt the Summary of Deposits index (ISO timestamp).
- `dataset` (object): The staged full collection; present only at offset 0 when it exceeded limit and this deployment staged it as a dataframe.
- `error` (object): Present when the call failed. Absent on success.
- `footprint` (array): Institution mode: its deposits and share per state, largest first.
- `geography` (object): The geography as applied; absent in institution mode.
- `institution` (object): The institution; present when it reported branches in scope.
- `institutions` (array): Market mode: one page of the institutions ranked by deposits (ties by CERT), starting at offset.
- `market` (object): Market modes: the whole market in the geography.
- `mode` (string): institution (cert only), market (geography only), or institution_in_market (both).
- `next_offset` (integer): Offset of the next page; present while rows remain past this page.
- `notice` (string): Guidance when nothing matched, more pages remain, the page is past the end, or where the full collection is staged.
- `position` (object): institution_in_market: present when the institution has branches in the market.
- `shown` (number): Rows on this page.
- `total_rows` (integer): Full count of the branches (institution modes) or ranked institutions (market).
- `truncated` (boolean): True when rows remain past this page (next_offset is set).
- `year` (integer): Survey year (deposits as of June 30).
- `year_defaulted` (boolean): True when year was omitted and the latest survey was used.

### `fdic_list_reference` (~175 tokens)

List FDIC reference vocabulary

List the vocabulary the other fdic_ tools accept and return: every financial metric name with its FDIC field, unit, and basis (single quarter, year-to-date, or point in time), bank charter classes, failure resolution methods, the structure-change codes fdic_get_institution_history reports and the event type each maps to, insurance funds, the asset bands fdic_compare_peers uses, and the years each dataset covers. Served from built-in tables; no request to FDIC.

Input parameters:

- `topic` (string, required): Which table to list: metrics (names, FDIC fields, units, basis, default set), bank_classes, failure_methods, change_codes (FDIC structure-change codes with their event type and level), insurance_fund…

Output parameters:

- `entries` (array): Every entry of the topic, in table order.
- `error` (object): Present when the call failed. Absent on success.
- `topic` (string): The topic listed.

### `fdic_dataframe_describe` (~265 tokens)

Describe staged dataframes

Describe the df_<id> dataframes that fdic_query_financials and fdic_get_deposits staged when a result at offset 0 was larger than one page, plus any that fdic_dataframe_query saved with register_as. Pass name (from a dataset field) for one dataframe in full: source tool, the parameters it was called with, row count, creation and expiry time, column schema, and the unit and basis of each amount, ratio, or count column (thousands of dollars, percent, or count). Read a table's columns this way before writing SQL for fdic_dataframe_query. Omit name to list the live dataframes, newest first, 50 per page, as name, source tool, row count, and expiry only. A deployment that serves HTTP without authentication, where every caller shares one canvas, does not list; there, pass the name a dataset field returned.

Input parameters:

- `name` (string): A dataframe name (df_XXXXX_XXXXX, from a dataset field) for its provenance, columns, and units; omit to list the live dataframes where this deployment allows it.
- `offset` (integer): Listed dataframes to skip; pass next_offset from the previous page. Ignored when name is set.

Output parameters:

- `cap` (number): Dataframes per page of the listing.
- `dataframes` (array): The named dataframe in full, or one page of the live dataframes as summary rows, newest first; empty when none matched.
- `error` (object): Present when the call failed. Absent on success.
- `next_offset` (integer): Offset of the next page of the listing; present when more dataframes remain.
- `notice` (string): Guidance when nothing matched, the page is past the end, the page starts past the first dataframe, or more pages remain.
- `shown` (number): Dataframes listed on this page.
- `total` (integer): Live dataframes across all pages of the listing; with name, 1 or 0.
- `truncated` (boolean): True when more dataframes remain beyond this page.

### `fdic_dataframe_query` (~394 tokens)

Query staged dataframes with SQL

Run one read-only SELECT (DuckDB SQL) across the df_<id> dataframes that fdic_query_financials and fdic_get_deposits staged or an earlier register_as saved; joins, aggregates, window functions, and CTEs work. Before writing SQL, pass each table name to fdic_dataframe_describe to read its columns. DOUBLE columns come back as JSON numbers and dollar columns are thousands of US dollars; BIGINT results such as COUNT(*) come back as strings, so CAST them to INTEGER or DOUBLE for arithmetic. Writes, DDL, file-reading functions, and system catalogs are rejected. register_as materializes the result as a new dataframe with a fresh TTL.

Input parameters:

- `preview` (integer): Rows to return inline; defaults to the effective row_limit and is clamped to it. Set it low when register_as keeps the full result.
- `register_as` (string): Materialize the full result as a new dataframe under this unused name (df_XXXXX_XXXXX: uppercase letters and digits). A name already staged fails as register_as_clash — including on a repeat of a cal…
- `row_limit` (integer): Requested materialization cap (default 1,000; hard input ceiling 1,000,000), clamped to the execution cap of 10,000. Without register_as, row_count_capped reports more matches; continue with ordered…
- `sql` (string, required): One SELECT against df_<id> tables named in a dataset field or by fdic_dataframe_describe, up to 20,000 characters.

Output parameters:

- `cap` (number): The cap that bound: preview when lower, else row_limit.
- `columns` (array): Columns in projection order.
- `effective_preview` (integer): Inline row cap after clamping preview to the effective row_limit.
- `effective_row_limit` (integer): Effective row_limit, at most 10,000.
- `error` (object): Present when the call failed. Absent on success.
- `expires_at` (string): When the register_as dataframe is dropped (ISO 8601).
- `notice` (string): Guidance when the query returned no rows or a cap withheld some.
- `registered_as` (string): Name of the dataframe register_as created.
- `requested_preview` (integer): Explicit preview before clamping; absent when omitted.
- `requested_row_limit` (integer): Requested row_limit before the execution cap.
- `row_count` (integer): Rows the query produced, up to effective_row_limit; with register_as, the exact count of the new dataframe.
- `row_count_capped` (boolean): True when the query matched more rows than effective_row_limit, so row_count is that cap.
- `rows` (array): Result rows, bounded by preview and row_limit.
- `shown` (number): Rows returned inline.
- `truncated` (boolean): True when rows were withheld by preview or row_limit.
