Overview

AI-generated overview

Lets an assistant search an index of x402-payable APIs and data sources and fetch them through a hosted proxy that pays and returns a signed receipt.

What you can do
  • Search the x402 economy's indexed services, ranked by distinct payers, and browse a curated catalog of procurable sources
  • Fetch a source through the hosted proxy, which fronts payment on the seller's chain and returns the goods plus a signed delivery receipt
  • Scan a local directory for security issues before shipping
  • Query the same capabilities over a free HTTP manifest and catalog API, with per-call pricing for procurement
When to use it
Useful when an assistant needs data or API results from paid x402 services and you want a single hosted route that handles payment and returns verifiable provenance, without holding a wallet on the seller's chain. Also handy for a quick pre-ship security scan of a local directory.
Requirements
Node.js 18 or newer; runs locally over stdio, typically launched with npx. Network access to the hosted supership endpoint, which defaults to a Crest Systems domain and can be overridden with the SUPERSHIP_URL environment variable. No authentication is declared.
Before you install
Procurement is paid per call after the first free runs, so the hosted service spends money on your behalf; the server itself is described as holding no keys and moving no money locally. Requests and the sources you ask for are sent to the third-party hosted endpoint, and the optional SUPERSHIP_URL override redirects that traffic. The directory scan reads local files.

Installation

In SourceWeft

  1. Open Supership Scan in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

supership

The search engine and clearing house for the agent economy. Built by Crest Deployment Systems.

supership indexes the entire x402 economy -- 52,000 services -- so an AI agent can find the right data and fetch it with a receipt. Reading the menu is free. Fetching through supership returns the goods plus a signed delivery receipt: proof of what you got, from where, settled on-chain. That is the part going direct can never give you.

Install

bash
npm install -g supership-scan

Published on npm as supership-scan (the original name; kept for install continuity).

Requires Node.js 18+.

MCP server

bash
npx -y -p supership-scan supership-mcp

Or wire it into any MCP client (Claude Code, Cursor, Windsurf):

json
{  "mcpServers": {    "supership": {      "command": "npx",      "args": ["-y", "-p", "supership-scan", "supership-mcp"]    }  }}

Tools

ToolWhat it does
manifestSearch the whole x402 economy (52,000 services) for what you need. Ranked by distinct payers -- real adoption, not call counts. Free.
procureFetch any source. supership fronts payment across any chain, delivers the goods, and returns a signed receipt. No wallet needed on the seller's chain. First runs free.
list_catalogBrowse a curated catalog of procurable sources.
scan_directoryScan a local directory for security issues before you ship.

Free menu, paid kitchen

  • The menu is free. manifest shows the real market: every relevant source, free or paid, ranked by who actually paid for it. That ranking is the part you cannot compute yourself -- it takes the whole index and the payment history.
  • The kitchen is the product. When you procure, supership crosses to the source (on whatever chain it lives), pays, takes delivery, and hands you the goods plus a signed delivery receipt -- an Ed25519 record of what was delivered (source, SHA-256 of the goods, settlement tx, timestamp), verifiable at /api/pubkey. That receipt is the provenance going direct cannot give you.

What supership does not do

  • It does not sell the data. It indexes the market and delivers what you ask for, with a receipt.
  • It does not hold your funds. The MCP server holds no keys and moves no money locally.
  • It does not give investment advice.
