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 → Why this is hard to score →
Endpoint Security57
- 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability74
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 315 tokens (~78/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 Coverage86
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 57% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the Neuronto Payments: x402 facilitator MCP server?
Neuronto Payments: x402 facilitator is a hosted endpoint at https://pay.neuronto.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
facilitator_status ~61
What this x402 facilitator can settle right now: the live networks and schemes, whether the echo merchant is serving, the state of address screening, observed availability and settlement counts. Call this before advertising a price, because a network that cannot settle is withdrawn here first.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
find_paid_resource ~104
Search the catalogue of resources that have been paid for through this facilitator: the URL, the terms, the method, and the input and output shapes where the merchant published them. A resource is listed only after a real settlement and a probe, so nothing here is a claim by its owner.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| network | string | – | CAIP-2 network to restrict to. |
| query | string | – | Words to match in the URL or description. |
No output schema declared.
No examples provided.
integration_snippet ~87
Working code to start charging for a route through this facilitator, in the language and framework you name, plus a live URL to test the client against. Copy it as it is; the only thing to change is the wallet.
| Name | Type | Req | Description |
|---|---|---|---|
| framework | string | – | – |
| language | string | – | – |
| role | string | – | server to charge for a route, client to pay for one. |
No output schema declared.
No examples provided.
settlement_price ~63
What a settlement costs through this facilitator, per network, with the basis it was computed from. Free while the service is in launch pricing.
| Name | Type | Req | Description |
|---|---|---|---|
| network | string | – | CAIP-2 network, for example eip155:8453. Omit for every network. |
