Overview

AI-generated overview

Remote MCP server that lets an assistant search a small catalog of original Chinese book reviews and get x402 payment instructions to buy full articles.

What you can do
  • Search public bilingual catalog metadata by keyword or natural-language question, or list all items with an empty query
  • Retrieve purchase instructions for a chosen article: paid API URL, request schema, payment network, price and workflow
  • No tool returns private article text; the full Markdown is only delivered by a separate paid HTTP request after an x402 payment
When to use it
Useful when you want an assistant to discover Chinese-language book reviews on topics like child development, history, economics or language, and to prepare a paid purchase of one complete review. The catalog is small (six reviews), so it is a narrow, early-release service.
Requirements
A client that can connect to a remote streamable HTTP MCP endpoint; no account, API key or header is declared. Buying a full article additionally requires an x402 v2 compatible client, a Base mainnet wallet with USDC, and a separate POST request to the paid article API.
Before you install
Purchases cost 0.95 USDC per article on Base mainnet and are real on-chain payments; verify network, token, amount and recipient against trusted expectations before signing, and never send private keys to the service. One payment buys one response, not a subscription, and failed or ambiguous attempts should be checked for settlement before retrying to avoid duplicate charges. Search results are metadata only.

Installation

In SourceWeft

  1. Open Seller Agent — Chinese Book Review Catalog in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.lihaoshall%2Fseller-agent/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

README

Seller Agent v1.2

Discover original Chinese-language book reviews for free; purchase one complete review for $0.95 USDC on Base mainnet.

Seller Agent is an AI-agent-facing content service built with the Model Context Protocol (MCP) and x402 v2 HTTP payments. The public MCP tools expose catalog metadata and purchase instructions, not the private article text.

Live endpoints

  • MCP server: https://agent-content-store.sthinking.workers.dev/mcp
  • Paid full-article API: POST https://agent-content-store.sthinking.workers.dev/api/purchase-article

All six reviews are original Chinese-language reviews of the books listed above. They are not the books themselves. Free discovery metadata supports Chinese and English queries.

Free MCP tools

  • search_library — Search the public catalog by keywords or natural-language questions; an empty query lists available items.
  • get_purchase_instructions — Get the paid API request format and payment instructions for a selected content_id.

MCP does not deliver private full-article text. Clients must support connecting to a remote MCP endpoint to use these tools.

Buy a full article

Make a JSON POST request (example):

bash
curl -i -X POST "https://agent-content-store.sthinking.workers.dev/api/purchase-article" \  -H "Content-Type: application/json" \  -d '{"content_id":"review-003"}'

An unpaid request returns HTTP 402 with an x402 v2 PAYMENT-REQUIRED header. A compatible x402 client can validate the payment requirements, obtain buyer authorization, and retry the same request with a valid payment proof.

Payment parameters:

Amount950000 USDC base units

The PAYMENT-REQUIRED response is the authoritative live payment offer. Buyers should verify network, token, amount, and recipient against trusted expectations before signing. Do not send private keys to this service.

A successful paid request returns JSON with success: true and the full original Markdown in article.content (along with the article's ID, title, language, and source-book metadata).

Purchase semantics: One successful x402 payment authorizes one complete-article HTTP response. Buyers can save the text they receive. This is not a subscription, an account-based permanent entitlement, or DRM.

If a payment attempt times out or fails ambiguously, check settlement status before retrying to avoid accidental duplicate charges.

Service status and scope

This is an early public release with six reviews. The legacy /api/query-content excerpt endpoint has been retired. Article discovery is free; complete articles are paid. This repository contains documentation only—no private reviews, wallets, or backend source code.
