## 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 2026-09-21.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 70/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 486 tokens (~243/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - 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 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 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.

## Install

### How do I install the Stablecoin reserve attestations MCP server?

Stablecoin reserve attestations is a hosted endpoint at https://agentwares-stablecoin.vercel.app/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.

### `stablecoin_reserves` (~250 tokens)

Stablecoin reserve attestation

Latest parsed reserve attestation for one stablecoin issuer as JSON: as_of date, total reserves, composition by asset category, attestor, source_url, current on-chain supply (DefiLlama) and the reserve ratio. Use it when an agent needs machine-readable backing data instead of reading the issuer's PDF. Pass symbol (USDC, USDT, ...) or issuer; period=YYYY-MM selects an earlier month. Issuers without a third-party attestation return supply only with confidence 'none'. Paid: $0.02 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.

Input parameters:

- `issuer` (string): Issuer name or registry id when the symbol is unknown, e.g. "circle" or "paxos"
- `period` (string): Report month as YYYY-MM. Default: the newest parsed month. See history_available.
- `sample` (boolean): Set true to return an example response at no charge (sample mode). Default false.
- `symbol` (string): Token symbol, case-insensitive: USDC, USDT, PYUSD, RLUSD, ... (see stablecoin_list_issuers)

Output parameters:

- `as_of` (string|null)
- `attestation_type` (string)
- `attestor` (string|null)
- `backing` (string)
- `cadence` (string)
- `checks`
- `composition` (array)
- `confidence` (string)
- `currency` (string)
- `history_available` (array)
- `issued_on` (string|null)
- `issuer` (string)
- `name` (string)
- `notice` (string)
- `onchain_supply`
- `peg` (string)
- `period` (string|null)
- `report_url` (string|null)
- `reserve_ratio` (number|null)
- `reserve_ratio_vs_onchain_supply` (number|null)
- `sample` (boolean)
- `source_url` (string)
- `sources` (array)
- `symbol` (string)
- `tokens_in_circulation_reported` (number|null)
- `total_reserves_usd` (number|null)

### `stablecoin_list_issuers` (~55 tokens)

List covered stablecoin issuers

Free. Lists every issuer in the registry with symbol, issuer, attestation type, attestor, cadence, source_url and which months are parsed. Call it first to pick a symbol for stablecoin_reserves.

Output parameters:

- `count` (number)
- `issuers` (array)
- `notice` (string)
- `price_usd_per_reserves_call` (number)
