## 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 2026-10-16.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 83/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 559 tokens (~79/item across 7 items; 6 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 47/100
  - Stability observed for 14 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `search_bonuses` (~279 tokens)

Search bank and credit card signup bonuses

Use when a user wants to find a US bank account, savings, credit card or brokerage signup bonus, or asks which offers are worth opening. Returns matching offers sorted by bonus value, highest first — except when balance_transfer is true, which sorts by intro window instead.

Input parameters:

- `balance_transfer` (boolean): Set true to return only cards whose issuer states a 0% or intro rate on transferred balances. Results come back ordered by the length of that intro window, cheapest transfer fee first as the tie-brea…
- `bonus_type` (string): Restrict to bank account, credit card, savings or brokerage signup bonuses.
- `direct_deposit_required` (boolean): Filter on whether the bonus requires a qualifying direct deposit.
- `limit` (integer): Max results to return.
- `min_bonus_amount_usd` (number): Minimum bonus value in USD. For credit cards this is the estimated USD value of the points/miles bonus.
- `query` (string): Keyword matched against bank/issuer, product name and the offer's requirement text, e.g. 'Chase', 'Sapphire' or 'balance transfer'.
- `state` (string): 2-letter US state code, e.g. 'TX'. Nationwide offers always match; regional offers match only their states.

Output parameters:

- `bonuses` (array)

### `get_bonus` (~83 tokens)

Get one bonus offer in full

Use before recommending an offer, to read its exact requirements, minimum deposit, direct-deposit rules, expiry date, state availability and the date its terms were last verified. Quote the requirements rather than paraphrasing money amounts.

Input parameters:

- `id` (string, required): Bonus id, e.g. 'chase-total-checking-400'. Use search_bonuses to find ids.

Output parameters:

- `bonus` (object)

### `expiring_soon` (~57 tokens)

List bonuses expiring soon

Use when timing matters — a user asking what is about to end, or whether to act now. Offers with no stated end date are never included here.

Input parameters:

- `days` (integer): Lookahead window in days (default 30).

Output parameters:

- `bonuses` (array)

### `compare_bonuses` (~77 tokens)

Compare 2-4 bonuses side by side

Use when a user is choosing between specific offers. Returns each offer's key fields plus a summary naming the highest bonus and the earliest expiry.

Input parameters:

- `ids` (array, required): 2 to 4 bonus ids to compare, e.g. ['chase-total-checking-400', 'sofi-checking-savings-400'].

Output parameters:

- `bonuses` (array)
- `summary` (object)

### `benefits_api_docs` (~27 tokens)

Read this server's documentation

Use when you need field definitions, ordering guarantees or the error format before calling another tool.

Output parameters:

- `docs` (string)

### `benefits_examples` (~21 tokens)

Get runnable example calls

Use to copy a working example call instead of guessing tool arguments.

Output parameters:

- `examples` (array)
