Mechanism, not adjectives

Why us

Most MCP sites are indexes: they tell you a server exists and step out of the way. We stand in the path of the call — which is what lets us meter it, refuse it before it costs anything, and print figures that were measured rather than supplied — and, when a publisher would rather not run anything, to host the server ourselves behind the same address. Everything below about anybody else was read from their own site on 13 August 2026.

How a call is answered

six checks, in the order the code runs them
01
The keyRecognised, not revoked, not expired — and the account behind it is not suspended.
02
The listingLive, not frozen, a server rather than a skill, and delivered through the gateway.
03
The endpointVerified, and not held open by the circuit breaker after three consecutive failures.
04
The toolOne the listing published — and a write tool is refused outright for a read-only key.
05
The limitsPlan rate, monthly ceiling, install allowance, per-minute rate. In that order.
ForwardedOnly now does the call leave us. A refusal is not billed, and neither is a 5xx from the server upstream.

Everything from the suspension check onward is written to a call log both sides can read. A refusal that happens before we know whose key it is — a malformed body, an unknown listing — is answered without a log line, because there is no account to write it against.

Three ways to ship a server

the split is 88/12 in all three
Free and local
runs on the buyer’s machine

Ship source or a package. It installs from your own address and costs you nothing — the scan and the grade are free on every plan.

Your endpoint
runs where you already run it

We mint the token your server checks, meter the calls, enforce the plan and stop them when a subscription ends.

Hosted by usnew
runs on our infrastructure

Hand us the server at publication and we run it behind its listing. Same gateway address, same install command, same split.

A price needs the gateway in the path — that is what makes a cancelled subscription actually stop and an allowance countable — so a paid listing is either your endpoint or ours. Free listings can be any of the three.

Questions people ask

Why is most of the catalogue imported?
Because an empty catalogue helps nobody, and the MCP ecosystem is public. Imported entries must pass a real test that they are MCP servers rather than merely named like one; they install from their own source; they are always free, because we do not sell on behalf of somebody who never signed up; and the author can claim them, correct them or have them removed without giving a reason.
Why do some listings show no calls or latency?
Because those calls never came through us. A direct listing is installed from its own source and answers where it runs, so printing a zero would be a claim about an experiment nobody performed. The blank is the honest cell, and latency is withheld below twenty calls, where a percentile would be arithmetic rather than information.
Does a good grade mean a server is safe?
No. It means a specific build, at a specific moment, was read by a scanner whose rules are published, and that it produced that letter. A dependency that is clean in March can be taken over in June without the listing changing a line, which is why every report carries the date and the version it was produced against.
Do you run my server for me?
We can. Hand us the server at publication and we run it behind its listing, or keep your own endpoint and let us authenticate to it with a token we mint and you rotate. The buyer sees the same gateway address either way, and the 88/12 split does not change. What we do not offer is general compute.
What does the 12% pay for?
The gateway and its metering, the call accounting behind your invoice, checkout and tax, the payout machinery, disputes, the scanning that is free on every plan, and the catalogue itself. It is not a listing fee — an unsold listing costs its publisher nothing.
Why trust a comparison written by one of the nine?
You shouldn’t, on its own — which is why every column is quoted from that company’s own pages on a named date, why a gap is written as “not published” rather than as “no”, and why the awkward rows about us sit in the same table as the flattering ones. Find a cell that is wrong and we will fix it.

Take the grade, with or without the gateway

If your servers are open source and free, the scan costs you nothing and the listing stays yours to claim. If you sell, the gateway is what makes a cancelled subscription actually stop.
