## 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 2026-10-18.

- **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**: 61/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1721 tokens (~344/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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 (5)

### `nulucre_get_stellar_wallet_score` (~753 tokens)

Get Stellar Wallet Reputation Score

Get a 0-100 trust score for a Stellar wallet address (G...) from Nulucre, a live Stellar-native wallet reputation oracle.

The score is computed from 8 signals pulled directly from the Stellar Horizon API and Stellar Expert — account age, transaction volume, asset diversity, SDEX DEX participation, network trust, claimable balance activity, Soroban contract interactions, and liquidity pool participation, plus a spam detection penalty. No EVM data is used.

Every score includes a real-time sanctions screening result against the OFAC SDN, OFAC Non-SDN, EU Financial Sanctions, and UN Security Council Sanctions lists. A wallet matching any of these lists automatically receives a score of 0 and status BLACKLISTED.

Use this tool to assess counterparty risk before an agent interacts with or pays a Stellar wallet — for example before executing a payment, approving a swap counterparty, or evaluating a new account.

Args:
  \- g_address (string): Stellar wallet address starting with 'G' (56 characters)
  \- signed (boolean): If true, request an ECDSA-P256 signed score for independent
    verification via Nulucre's public JWKS endpoint (default: false)
  \- response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns:
  For JSON format: Structured data with schema:
  {
    "wallet": string,
    "network": "stellar:pubnet",
    "score": number,            // 0-100

Input parameters:

- `g_address` (string, required): Stellar wallet address starting with 'G' (56 characters)
- `response_format` (string): Output format: 'markdown' for human-readable report or 'json' for machine-readable structured data
- `signed` (boolean): If true, requests an ECDSA-P256 cryptographically signed score for independent verification (higher cost endpoint)

### `nulucre_get_evm_wallet_score` (~518 tokens)

Get EVM Wallet Reputation Score

Get a 0-100 trust score for an EVM wallet address (0x...) from Nulucre, a multi-chain wallet reputation oracle covering 81+ chains.

The score is computed from on-chain data including wallet age, transaction volume, DeFi activity, and multi-chain presence, pulled from Etherscan, Moralis, Alchemy, and Ankr.

Use this tool to assess counterparty risk before an agent interacts with or pays an EVM wallet on Ethereum, Base, Polygon, Arbitrum, Optimism, or any of the 81+ supported chains.

Args:
  \- wallet (string): EVM wallet address starting with '0x' (42 characters)
  \- signed (boolean): If true, request an ECDSA-P256 signed score for independent
    verification via Nulucre's public JWKS endpoint (default: false)
  \- response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns:
  For JSON format: Structured data with schema:
  {
    "wallet": string,
    "score": number,            // 0-100
    "status": string,           // TRUSTED | VERIFIED | CAUTION | RISKY | BLACKLISTED
    "breakdown": {
      "<signalName>": { "score": number, "raw": string },
      ...
    },
    "chains"?: string[],
    "dataSource": string,
    "timestamp": string,
    "signature"?: string        // present only when signed=true
  }

Examples:
  \- Use when: "Is this Ethereum wallet trustworthy?" -> wallet="0xabc...", signed=false
  \- Use when: "Get a verifiable score for this 0x address" -> wallet="0xabc...", signed=true
  \- Don't use when: scoring a Stellar G... address (use nulucre_get_stellar_wallet_score instead)

Error Handling:
  \- Returns "Error: Invalid EVM wallet address" if the address format is invalid
  \- Returns a payment-required explanation if the free evaluation quota is exhausted

Input parameters:

- `response_format` (string): Output format: 'markdown' for human-readable report or 'json' for machine-readable structured data
