概覽

AI 產生的概覽

BridgeNode MCP 讓助理呼叫相容 OpenAI 的多模型對話補全,依次以 Solana USDC 透過 x402 付費,並提供免費模型與試用額度。

可以做什麼
  • 向支援的模型送出對話補全請求,支援 OpenAI 風格的 tools 與 tool_choice,並回傳工具呼叫
  • 列出可用模型及其價格
  • 在付費前估算一次對話請求的 USDC 費用
  • 免費模型與每個用戶端對付費模型的首次呼叫無須付款,之後的呼叫透過 x402 自動支付
適用情境
適合助理需要模型推論但不想註冊帳號或申請 API 金鑰的情境,也適合希望依次付費並設定消費上限、而非訂閱制的使用者。
執行需求
透過 npx 以本機 stdio 程序執行(需 Node.js),並代理到遠端 streamable-HTTP 端點,也可直接作為遠端端點使用。無須 API 金鑰或註冊。付費呼叫需要 Solana 錢包私鑰,放在 BRIDGENODE_WALLET_KEY 中,並可選用 BRIDGENODE_MAX_PER_CALL 與 BRIDGENODE_DAILY_CAP 設定消費上限。需要網路存取。
安裝前請注意
付費呼叫會花費真實的 Solana USDC;包裝程式會用 BRIDGENODE_WALLET_KEY 中的錢包私鑰自動簽署付款,該私鑰可支配資金,建議使用專用的低餘額錢包。消費策略預設為失敗即拒絕,但仍應主動設定。提示詞與請求會傳送給第三方 BridgeNode 服務。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 BridgeNode MCP,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.bridgenode-ai%2Fbridgenode-mcp/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

@bridgenode/mcp

[npm version] [npm downloads] [License: MIT-0] [CI] [Website] [BridgeNode on x402-list] [@bridgenode/mcp on AI Agents Listing] [GitHub Stars]

Built for AI agents — no API keys, no registration, pay-as-you-go with Solana USDC via x402. Start free: free models and 2 free calls on paid models per client, no wallet required.

BridgeNode MCP wrapper — stdio MCP server that proxies requests to the remote https://bridgenode.cc/mcp (streamable-HTTP) with automatic x402 payment (Solana USDC). No API keys, no registration.

Installation (one-command)

bash
claude mcp add bridgenode -s user -- npx -y @bridgenode/mcp@latest

Or manually (Claude Code, Cursor, other MCP clients):

json
{  "mcpServers": {    "bridgenode": {      "command": "npx",      "args": ["-y", "@bridgenode/mcp@latest"]    }  }}

Configuration (.env)

bash
# Solana wallet private key (base58) — agent's payment wallet# Optional — Solana wallet private key (base58). Needed only for PAID calls:# free models and the 2 free trials work without it.BRIDGENODE_WALLET_KEY=
# Spending policy (fail-closed)BRIDGENODE_MAX_PER_CALL=0.05BRIDGENODE_DAILY_CAP=1.0

Tools

  • chat_completions — AI inference (free models run without payment; the first 2 calls to a PAID model are free per client, then x402 payment is automatic). Accepts OpenAI-style tools / tool_choice — the model's answer then carries tool_calls (the wrapper passes arguments through unchanged)
  • list_models — model list (free)
  • get_price_estimate — estimate cost of a chat request (free)

How it works

  1. Local MCP client launches the wrapper via stdio
  2. Wrapper connects to https://bridgenode.cc/mcp (streamable HTTP)
  3. On tools/call receiving 402 (payment required) — the wrapper automatically signs the payment with BRIDGENODE_WALLET_KEY and retries the request
  4. Spending policy checks every payment BEFORE signing (fail-closed)

chat_completions

Chat completions with x402 payment

Send a chat completion request to any supported model. Free models are served without payment; the first calls to a PAID model are also free per client (free trials), after which x402 payment (Solana USDC) is required — an unpaid call returns 402 with the exact price; retry with _meta["x402/payment"]. Responses are non-streaming. Pass either mode (auto/eco/premium) or model (explicit id) — one of the two is required; model wins if both are sent. Use this tool to generate text; inspect models and prices first with the free list_models tool. Start with a FREE model (no payment at all) and keep max_tokens >= 200 — a thinking model spends part of that budget on reasoning, so a smaller limit can return an empty answer.

list_models

List available models and prices

List available models and their prices — free, no payment, no authentication required. Read-only: no state changes; data is served from the server's local config, so repeated calls return identical results (idempotent). Accepts no parameters: the input schema is an empty object, and any arguments passed are ignored. Calling it without arguments returns the complete catalog with per-token prices; there is no filtering, pagination, or configuration. Use this tool to inspect models and prices before calling the paid chat_completions tool. Same data as GET /v1/models (§5.2). Do not use it to generate text (use chat_completions) or to estimate a specific request's cost (use get_price_estimate).

無需輸入參數。

get_price_estimate

Estimate the cost of a chat request

Estimate the USDC cost of a chat completion request before paying — free, no payment, no authentication required. Read-only: no state changes and no external calls; the estimate is computed locally from server pricing config, so repeated calls with identical inputs return identical results (idempotent). Use this tool to check the exact price for a given model/mode, messages, and max_tokens before calling the paid chat_completions tool. Provide either mode (auto/eco/premium routing) or model (explicit id, mutually exclusive with mode); one of the two is required — if both are sent, model wins. mode values: auto = cheapest model fitting the context, eco = cheapest available, premium = best model.
