## 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 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 67/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1993 tokens (~86/item across 23 items; 23 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 73/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 18% 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 23 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 23 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.

## Common questions

### What is the Aether: Base onchain data & token risk (x402) MCP server?

Aether: Base onchain data & token risk (x402) is an MCP server listed in the public MCP registry as io.github.francosmit94-web/aether. Base token risk (honeypot sim), prices, balances, Basenames, tx data. Pay-per-call in USDC via x402. This page covers its hosted endpoint (https://aether-x402.vercel.app/mcp).

### Is the Aether: Base onchain data & token risk (x402) MCP server safe to use?

Aether: Base onchain data & token risk (x402) scores 84 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Aether: Base onchain data & token risk (x402) MCP server expose?

Aether: Base onchain data & token risk (x402) exposes 23 tools: base_token_risk_trial, base_token_risk, base_balance, base_erc20_balance, base_portfolio, and 18 more. Their descriptions and schemas cost roughly 1,993 tokens of context every time the server is loaded.

### Does the Aether: Base onchain data & token risk (x402) MCP server require authentication?

No. We connected to Aether: Base onchain data & token risk (x402) without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Aether: Base onchain data & token risk (x402) MCP server still maintained?

Aether: Base onchain data & token risk (x402) is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Aether: Base onchain data & token risk (x402) MCP server?

VerifyMCP ran 13 checks on Aether: Base onchain data & token risk (x402), covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
