已验证Streamable HTTP可网页运行网页搜索与抓取金融媒体与设计

概览

AI 生成的概览

远程 MCP 服务器，提供 cc0pedia CC0 数据库、CC0 图像生成与域名/网页情报工具，按次通过 Base 上的 x402 以 USDC 付费。

可以做什么
  • 查询、搜索、验证并查询 CC0 创作者、合集、作品与合约的价格，含来源、许可与链上指针
  • 生成公有领域图像：莫奈、梵高、北斋、sartoshi、Darkfarms 风格，以及 mferGPT 图像、问答与 lore 服务
  • 获取 CC0 NFT 热门合集的每日摘要，含市场指标与叙述
  • 执行网页与域名情报检查：DNS、TLS、HTTP 安全头、邮件送达性、域名年龄、IP 地理位置、网页转文本
  • 检查数据质量：文本验收门、JSON 质量检查与 schema 漂移检查
  • 获取法币汇率与加密货币现货价格
适用场景
当助手需要 CC0 许可与来源事实、可安全使用的 CC0 生成图像，或快速的域名、DNS、安全头与数据质量检查，并且愿意按次支付少量 USDC 而不使用账号或 API 密钥时适用。
运行要求
远程 Streamable HTTP 端点，连接无需账号或 API 密钥。每次工具调用都是 Base 主网上以 USDC 支付的 x402 请求，因此需要支持 x402 的客户端（可签署 EIP-3009 USDC 授权）和已充值的钱包。initialize、tools/list、ping 等发现调用免费。
安装前请注意
每次调用都花费 USDC（约每次 0.01 至 0.07 美元，另有以 USDC 支付的打印订单），助手可能花掉真实资金，应设置支出上限。客户端需持有钱包私钥以签署支付授权。部分工具是转售的第三方服务并加收佣金。图像生成是异步的，需要轮询。工具列表动态发现，目录可能变化。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Cc0company Mcp，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

README

cc0company MCP

The largest machine-readable CC0 database (cc0pedia) + the whole cc0.company agent-services catalog, as a remote Model Context Protocol server. Pay-per-call over x402 (USDC on Base).

Endpoint: https://cc0.company/api/mcp — Streamable HTTP, JSON-RPC 2.0.

What it is

A remote MCP server that turns cc0.company's managed agent services into tools any AI agent can call:

  • cc0pedia read API — look up / search / verify / price any CC0 creator, NFT collection, token or work. Provenance, license, on-chain pointers (contracts, chains, OpenSea slugs) and live market data over the largest structured CC0 database.
  • CC0 image generation — fine-tuned models whose output is public domain.
  • Market data — a daily digest of the top CC0 NFT collections.
  • Third-party agents — re-brokered over x402 (e.g. mfergpt).

Tools are discovered live from the catalog (tools/list), so the set grows over time without changing your client.

Why agents pay

cc0pedia is a public good; serving it to autonomous agents at scale is not. Every tool call is a tiny x402 micropayment — the agentic economy in one request: an agent verifies a CC0 license, pulls provenance + market data, and pays for exactly what it used, with no account and no API key.

Connect

Claude Code

bash
claude mcp add --transport http cc0pedia https://cc0.company/api/mcp

Cursor — .cursor/mcp.json

Any MCP client — Streamable HTTP transport, the URL above. No auth to connect.

Payment — x402

Every tools/call is a paid x402 request. Free: initialize, tools/list, ping.

FacilitatorCoinbase CDP

Flow: the first call returns HTTP 402 with the challenge in the PAYMENT-REQUIRED header. Your x402 client signs an EIP-3009 USDC authorization and retries with the PAYMENT-SIGNATURE header; the facilitator verifies + settles and the tool runs. Use an x402-enabled client (wrap your MCP transport's fetch with x402). Pay only for what you use: a call that resolves nothing returns a 4xx and the charge is cancelled — you are never billed for an empty answer.

See examples/ for a working free-discovery script and an end-to-end paid call.
