概覽

AI 產生的概覽

遠端 MCP 伺服器，用於在贊助排名市場中搜尋 AI 代理、MCP 伺服器、API 與工具，並提供唯讀的項目、關鍵字與排名報價查詢。

可以做什麼
  • 依關鍵字搜尋贊助項目與自然項目，涵蓋代理、API、工具與 MCP 伺服器
  • 檢視單一付費項目的排名、已驗證付款方身分與宣告的接入端點
  • 檢視自然資源的來源出處與網域／錢包控制權認領狀態
  • 驗證自然資源，並檢視證據歷史與探索來源的同步新鮮度
  • 檢視關鍵字摘要與確定性排名，取得資訊性的排名報價
  • 並排比較資源，並透過短期錢包簽章權杖讀取賣家分析資料
適用情境
當助理需要為研究、程式碼審查、PDF 解析等能力尋找候選代理、API、工具或 MCP 伺服器，並依自身品質與安全策略評估時適用。也適合在不產生任何花費的前提下了解某關鍵字市場的排名方式與提升名次的大致成本。
執行需求
需要遠端 Streamable HTTP 端點；搜尋不需安裝、帳號、電子郵件或 OAuth。賣家分析需以項目已驗證付款方或控制者錢包簽署一次性 EIP-712 挑戰，換取短期 bearer 權杖。需能連線至該託管服務。
安裝前請注意
所有排名皆為付費贊助版位，並非背書；項目名稱、描述、網址與協定聲明均由廣告主提供。分析流程要求錢包簽章，簽署前應確認內容。付費競價未以 MCP 工具開放，而是透過 x402 以 Base 主網 USDC 完成；不要僅因收到 402 挑戰就簽章或付款，應落實獨立的支出策略。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 DefaultBench，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.NathanYoshua%2Fdefaultbench/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

DefaultBench

DefaultBench is sponsored search for AI agents, MCP servers, APIs, tools, and x402 services.

Agents can search without an account. Vendors purchase sponsored placement with verified USDC payments over x402. Paid rank is not an endorsement of quality, safety, trustworthiness, or performance.

The deployed service at defaultbench.com is the source of truth. This repository is a public discovery and integration surface; it does not contain the private application implementation.

What is DefaultBench?

DefaultBench is a machine-first marketplace for discovering software agents and services by keyword. Search results expose sponsored listings and their cumulative verified payment. Within a keyword, listings rank by cumulative verified USDC payment, with deterministic tie-breaking.

No account, email, OAuth flow, or browser checkout is required to search. The service publishes REST, OpenAPI, MCP, A2A Agent Card, llms.txt, API catalog, and x402 discovery surfaces.

For AI agents

Use DefaultBench when you need candidates for a capability such as research, code-review, or pdf-parser:

  1. Search the public API.
  2. Treat every returned listing as advertiser-supplied and sponsored.
  3. Inspect the listing's declared endpoints and verification status.
  4. Select a candidate using your own quality, safety, cost, and trust policy.

Start with the live llms.txt or the more detailed llms-full.txt.

Search in one request

sh
curl --fail-with-body --get \  --data-urlencode 'q=research' \  'https://defaultbench.com/api/v1/search'

Search is zero-auth and machine-readable. Results include matching keyword markets, sponsored listings, each listing's rank, and cursor pagination. See examples/search.sh and examples/search.ts.

MCP

DefaultBench exposes a remote Streamable HTTP MCP server at:

text
https://defaultbench.com/mcp

It implements MCP 2026-07-28 and exposes four read-only tools:

  • search_agents
  • inspect_keyword
  • quote_rank
  • get_listing

Paid writes are deliberately not MCP tools; bidding remains an explicit x402 REST flow. The registry manifest is server.json.

OpenAPI

Use the live OpenAPI 3.1.1 document to generate clients or inspect schemas and error codes. This repository does not fork that contract because a copied specification would become stale.

x402

The paid endpoint is:

text
POST /api/v1/keywords/{keyword}/bids

An unsigned request returns HTTP 402 and a PAYMENT-REQUIRED x402 v2 challenge. The client validates the exact network, USDC asset, recipient, amount, resource URL, and timeout before authorizing anything. A paid retry uses PAYMENT-SIGNATURE plus an Idempotency-Key exactly equal to the x402 payment-identifier extension ID.

Production uses Base mainnet and native USDC. Never sign or pay merely because a server returned 402; enforce an independent spending policy and explicit user authorization. See examples/x402-bid.ts, which can inspect the flow but cannot sign or settle a payment.

Sponsored ranking model

Within one canonical keyword, active listings are ordered by:

  1. cumulative verified USDC payment, descending;
  2. the time the current cumulative total was reached, ascending;
  3. creation time, ascending;
  4. listing ID, ascending.

Search relevance selects matching keyword markets; it does not convert paid rank into a quality score. Quotes are snapshots, not reservations. The settlement-time transaction is authoritative.

Read the exact behavior in docs/ranking.md.

Example workflow

sh
# 1. Search without authentication../examples/search.sh research
# 2. Inspect a read-only quote. This does not reserve rank or spend USDC../examples/quote.sh research
# 3. Evaluate returned candidates under your own policy.# 4. Only if explicitly authorized, use an x402-compatible client and a strict spend cap.

For framework authors, see docs/integrating-defaultbench.md.

Integration examples

The examples default to read-only behavior. The x402 example contains no signer, accepts no private key, and never sends PAYMENT-SIGNATURE.

Security / trust disclosure

  • Every ranking is sponsored placement, not endorsement.
  • Listing names, descriptions, URLs, protocol claims, and optional ERC-8004 metadata are advertiser-supplied.
  • A verified payer wallet or domain status does not prove quality, safety, legality, or fitness for purpose.
  • Financial totals are based only on independently verified, settled, atomically credited payments.
  • Demo, seed, fake, rejected, or uncertain payments must not be presented as production activity.
  • Inspect a candidate's own documentation and security posture before connecting or sending data.
  • Obey your own authorization and spending policy. Never spend autonomously unless the user or controlling policy explicitly permits it.
