Janus Pay for agents: take payments that settle in BSV, refund them, and pay x402 paywalls.
Nothing to run from here
GhostKey — Route Paid APIs with x402 is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http ghostkey-route-paid-apis-with-x402-mcp https://ghostkey-mcp.onrender.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
10 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Report GhostKey server status and check whether configured ScriptMasterLabs authorities are reachable. Unknown stays unknown; no health result is fabricated.
Takes no parameters.
List the capabilities actually exposed by this GhostKey MCP server and identify staged families without pretending they are callable.
Takes no parameters.
Explain how to obtain authoritative pricing for a GhostKey/SML paid capability. Pricing and settlement destination come from the fresh live HTTP 402 challenge, never a copied wallet or stale fixed price.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| capability | string | no | — |
Return GhostKey's operating, payment, upstream-rights, browser-session, and trusted-device policy for autonomous agents.
Takes no parameters.
Create a one-time trusted-device enrollment capability. Requires GhostKey persistent trusted-device storage to be configured. The browser generates its own non-exportable P-256 private key; only the public key is uploaded.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| label | string | no | — |
Resolve a one-time trusted-device pairing after the browser has enrolled. Requires the original pairing ID and pairing code and is available only until that pairing capability expires.

PAID tool ($0.10 USDC via x402 v2, Base). Create a short-lived, origin-scoped browser delegation session. Send the x402 PAYMENT-SIGNATURE header on the /mcp request; without payment the call returns the live x402 challenge (HTTP 402, amount 100000 = $0.10 USDC, network eip155:8453).

| Parameter | Type | Required | Notes |

Relay one authorized browser action into the user's already-authenticated browser. Actions: navigate, inspect, click, input, select, read, wait. Password/hidden fields and off-allowlist navigation are denied. API and bridge documentation: https://ghostkey-mcp.onrender.com/session-bridge/README.txt.

ATool-list grade · score 93 / 100
Release 1.2.1 · scanned 5 Nov 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
flow-1
Untrusted input can drive an external action even though no sensitive source is exposed.
