## 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 2026-09-28.

- **Endpoint Security**: 57/100
  - 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 20 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.
  - 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**: 64/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 2075 tokens (~103/item across 20 items; 20 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (70% 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 20 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 20 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).

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

First indexed and scored.

## MCP tools (20)

### `invoice_preflight_quote` (~86 tokens)

FREE, no wallet or document upload: choose the lowest priced Invoice Preflight tool from document type, PDF page count, and optional byte size. Call this before a paid invoice tool when the tier is uncertain. It does not inspect or validate the document.

### `check_url` (~91 tokens)

Paid Agent Preflight URL check ($0.005 USDC on Base). Call before an agent opens, follows, downloads from, or trusts an unknown URL. Performs deterministic checks, safely inspects HTTPS redirects without loading page content, blocks localhost/private addresses, and optionally queries Google Web Risk when configured. No LLM is used. A clean result is not a guarantee of safety.

Input parameters:

- `url` (string, required)

### `scan_content` (~116 tokens)

Paid Untrusted Content Security Layer ($0.005 USDC on Base). Scan untrusted text, HTML, Markdown, email, document text, API responses, and tool outputs before your agent adds them to context, follows their instructions, or acts. Returns risk score, risk categories, recommendation, and sanitized plain text when possible. Bounded deterministic local scanning; no external LLM or provider call. Maximum 100000 characters.

Input parameters:

Returns RPC execution/revert status, gas estimate, known top-level method decoding, direct ERC-20 transfer/approval calldata, unlimited approval warnings, and machine-readable risk. Standard JSON-RPC does not expose full internal token state changes; do not treat calldata decoding as a complete state diff. Never send a private key or seed phrase. This tool never signs, holds keys, or broadcasts.

Input parameters:

- `chain` (string, required)
- `data` (string, required)
- `from` (string, required)
- `to` (string, required)

### `check_wallet` (~122 tokens)

Paid Wallet Risk Check ($0.02 USDC on Base). Call before an agent sends funds to, accepts value from, grants an approval to, or interacts with an unfamiliar address. Checks whether the address is a wallet or contract and reads basic on-chain metadata. Sanctions, scam, drainer, mixer, and malicious-address intelligence are unknown unless a trusted provider is configured; without one, the result is cautious and low-confidence, not a safety certification. Never send private keys or seed phrases.

Input parameters:

- `address` (string, required)
- `chain` (string, required)

Output parameters:

- `address` (string)
- `address_type` (string)
- `cached` (boolean)

- `warnings` (array)

### `check_package` (~125 tokens)

Paid Package Safety Gate ($0.005 USDC on Base). Call before a coding agent installs, imports, or adds an unfamiliar npm dependency. Checks resolved package/version, OSV vulnerabilities and malware advisories, popular-name typosquatting, and install lifecycle scripts using static analysis only. Package code is never executed. Checks up to 10 direct dependencies when their versions can be resolved; it does not traverse transitive dependencies or assess maintainer history. Unknown coverage returns caution.

Input parameters:

- `ecosystem` (string, required)
- `package` (string, required)
- `version` (string)

### `route_tool` (~144 tokens)

Paid Agent Tool Router ($0.002 USDC on Base). Finds and ranks machine-payable MCP services and x402 HTTP endpoints before your agent chooses or pays a provider. Uses structured capability matching, hard constraints, price, observed latency/reliability, and cold-start trust confidence; no LLM call is required. Returns a recommendation only: it never invokes the selected provider or makes a second payment. Without X402_BAZAAR_DISCOVERY_URLS, results come only from this platform's local service registry and are marked degraded.

Input parameters:

- `capability` (string, required)
- `constraints` (object)
- `preferences` (object)

Output parameters:

- `alternatives` (array)
- `cached` (boolean)

- `routing_reason` (array)
- `success` (boolean)

### `get_live_quote` (~78 tokens)

Paid Live Product Quote ($0.01 USDC). Retrieves explicitly published product price and stock from a public HTTPS product page before an agent buys; shipping, tax and unknown values remain null. Never purchases.

Input parameters:

- `destination` (object)
- `quantity` (integer)
- `url` (string, required)
- `variant` (object)

### `extract_structured` (~73 tokens)

Paid Fresh Structured Extract ($0.01 USDC). Extracts a fresh webpage into a simple agent-defined typed JSON shape, with validation and per-field provenance. Uses static page data only; never executes page JavaScript and never fabricates missing fields.

Input parameters:

- `schema` (object)
- `url` (string, required)

### `check_change` (~62 tokens)

Paid Change / Diff Check ($0.001 USDC). Checks normalized text on a public HTTPS page against a previous SHA-256 hash, returning a compact diff when a prior snapshot is available.

Input parameters:

- `previous_hash` (string, required)
- `url` (string, required)

### `verify_claim` (~104 tokens)

Paid Freshness / Claim Verifier ($0.02 USDC). Checks a factual claim against fresh web search evidence and returns supported/contradicted/mixed/insufficient/stale with sources.

Input parameters:

- `claim` (string, required)
- `freshness_days` (integer)
- `preferred_domains` (array)

### `analyze_whale_activity` (~101 tokens)

Paid Whale Intelligence ($0.02 USDC). Summarizes large public GeckoTerminal-indexed DEX trades for a token address on a supported chain. Large-trader labels are size-based heuristics, not verified whale identities; data is not chain-wide. Wallet mode uses Helius (Solana) or Etherscan API V2 (EVM) when configured, returning recent indexed transactions only; it does not claim complete balances or whale labels.

Output parameters:

- `data` (object)
- `meta` (object)
