Available components
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. How we score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability71
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 455 tokens (~113/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management3
- Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail

clean_stats ~80
Get wash-adjusted x402 settlement volume per chain — spend that survives removal of funded loops and self-dealing cycles, which can differ from raw transfer totals by orders of magnitude. Returns clean settlement count, clean volume in USD and an as-of date per chain. Takes no arguments. Free, no key. These are the figures published on merona.io.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
mismatch_feed ~78
List every x402 endpoint currently advertising one payout address while asking payers for another, from merona's nightly probe of the public catalog. Returns the current entries with advertised vs live addresses, counts and as-of dates. Takes no arguments. Free, no key. Use payto_check instead when you already have a specific address or endpoint to check.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
payto_check ~119
Check whether an x402 endpoint or wallet pays out where it claims to, before your agent sends funds. Takes one wallet address or endpoint URL. Returns any catalog-vs-live payout mismatch, dated payout-rotation history, and whether the address has settled on chain. Free, no key. Use mismatch_feed instead to list every known mismatch. Records are dated facts, not accusations, and no record found is not a clearance.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Wallet address (0x… or base58) or endpoint URL/hostname to look up. |
No output schema declared.
No examples provided.
trust_score ~178
Score a specific seller wallet before paying it: wash-aware m.Score with an A–F grade, component breakdown, wash flags including multi-hop cycle detection, and the snapshot SHA so the result can be re-derived independently. Requires chain and address. Paid, $0.005 per call: pass payment=<base64 X-PAYMENT payload> to pay via x402, or api_key=<key>. Called without either, it returns x402 payment instructions rather than an error.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Seller wallet address to score. |
| api_key | string | – | merona API key. Alternative to per-call x402 payment. |
| chain | string | yes | Chain the seller settles on, e.g. base, polygon, solana. |
| payment | string | – | Base64 X-PAYMENT payload for a single x402 payment. |
No output schema declared.
No examples provided.
