## 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 2026-09-20.

- **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 15 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).
  - Context-footprint check failed: tool/resource definitions use about 2648 tokens (~176/item across 15 items; 15 tools + 0 resources), over budget; trim descriptions and params.
  - 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**: 97/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 92% 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 15 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Common questions

### What is the io.github.verixiaapps/hostdefi-x402 MCP server?

io.github.verixiaapps/hostdefi-x402 is an MCP server listed in the public MCP registry as io.github.verixiaapps/hostdefi-x402. Free token-safety scans + paid x402 verdicts, signals, radar & EVM swap quotes for AI agents. This page covers its hosted endpoint (https://hostdefi.com/api/v1/mcp).

### Is the io.github.verixiaapps/hostdefi-x402 MCP server safe to use?

io.github.verixiaapps/hostdefi-x402 scores 74 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 io.github.verixiaapps/hostdefi-x402 MCP server expose?

io.github.verixiaapps/hostdefi-x402 exposes 15 tools: scan_token, get_x402_pricing, token_risk_verdict, token_risk_deep, pregrad_signals, and 10 more. Their descriptions and schemas cost roughly 2,468 tokens of context every time the server is loaded.

### Does the io.github.verixiaapps/hostdefi-x402 MCP server require authentication?

No. We connected to io.github.verixiaapps/hostdefi-x402 without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the io.github.verixiaapps/hostdefi-x402 MCP server still maintained?

io.github.verixiaapps/hostdefi-x402 is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
