## 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**: 51/100
  - 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 17 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 check failed: the endpoint is reachable over plaintext HTTP.
  - 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**: 71/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1943 tokens (~114/item across 17 items; 17 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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 17 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 18 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

## Common questions

### What is the io.github.EzeAlfaro/legible-check MCP server?

io.github.EzeAlfaro/legible-check is an MCP server listed in the public MCP registry as io.github.EzeAlfaro/legible-check. On-chain RPC data for AI agents: block, gas, balance, tokens, receipts, decode. x402 USDC. This page covers its hosted endpoint (https://legible-check.ezealfa.workers.dev/mcp).

### Is the io.github.EzeAlfaro/legible-check MCP server safe to use?

io.github.EzeAlfaro/legible-check scores 59 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.EzeAlfaro/legible-check MCP server expose?

io.github.EzeAlfaro/legible-check exposes 17 tools: evm_block, evm_gas, evm_balance, evm_token_balance, evm_nonce, and 12 more. Their descriptions and schemas cost roughly 1,827 tokens of context every time the server is loaded.

### Does the io.github.EzeAlfaro/legible-check MCP server require authentication?

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

### Is the io.github.EzeAlfaro/legible-check MCP server still maintained?

io.github.EzeAlfaro/legible-check 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 io.github.EzeAlfaro/legible-check MCP server?

VerifyMCP ran 12 checks on io.github.EzeAlfaro/legible-check, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about io.github.EzeAlfaro/legible-check: Authorization. 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.
