## 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 2026-08-19.

- **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 1 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**: 86/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 189 tokens (~189/item across 1 items; 1 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (1)

### `pretrade` (~189 tokens)

Pre-trade execution & safety oracle. For a token, chain and trade size, returns REAL executable output, slippage AT SIZE, sellability (honeypot/tax detection by simulating the sell-back), ghost-liquidity flag, and MEV/sandwich risk. Covers long-tail and exotic DEXs (Uniswap V2/V3, Algebra, Solidly forks) and new chains that indexers read poorly. Simulated on-chain, not indexed. Call this before executing any swap to avoid honeypots, hidden taxes and bad fills.

Input parameters:

- `chain` (string, required): Chain key configured on the server, e.g. 'hyperevm', 'base', 'arbitrum'.
- `size_usd` (number, required): Intended trade size in USD (e.g. 500).
- `token` (string, required): ERC-20 token address (0x...) to evaluate.
