Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

swap
check_swap
Use this to check a Relay swap's status by requestId and confirm app-fee collection (appFees vs paidAppFees).
create_swap
Use this to swap any token on any chain into USDC on Base via Relay. Returns a headless deposit address (no signing) or an on-chain intent. App fees accrue on swaps.
onramp

Use this when a US user wants to buy USDC on Base with a card / Apple Pay / Google Pay. Returns a payment link a HUMAN must physically tap (fiat legs cannot be programmatically triggered); a human is notified. US-only guest checkout, <= $500/week.
provision
provision_wallet
Use this to create a gasless, non-custodial CDP Embedded Wallet address on Base (TEE keys, user-exportable) to receive routed value.

Onramperx — questions

Answers built from our own checks of this server.

What can Onramperx do?
It exposes 5 tools, read directly from the server on our last check. Among them: check_swap, create_onramp_session, create_swap, get_route_quote, provision_wallet. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Onramperx working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 43 of 91 checks got a reply (47.3%), average response time 263 ms. The bar chart above shows every period we have measured.
Is Onramperx still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
The registry lists Onramperx as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Onramperx?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Onramperx need an API key?
No. Onramperx completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Onramperx?
It answers our handshake in 263 ms on average, which is faster than 54% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
