AI 生成的概览

远程 MCP 端点,返回按费用、耗时和提供方排序的跨链桥接路线,通过 x402 按次以 USDC 付费。

可以做什么
查询不同链和代币之间的跨链桥接路线,返回按性价比排序的结果,包括桥接协议、预计耗时、美元费用、预计到账数量和分步路线(授权、桥接、兑换)。同一查询提供 GET 和 POST 两种调用方式。路线数据来自 LI.FI,覆盖多条链和多个桥。
适用场景
适合需要比较在不同区块链之间转移代币的最便宜或最快方式时使用,例如多链资产组合规划。不适用于查询 Gas 价格。
运行要求
通过 SSE 连接的远程 MCP 端点,无需本地安装包、注册或 API 密钥。每次调用按次以 Base L2 上的 USDC 付费,需使用支持 x402 且钱包有余额的客户端完成支付挑战。
安装前请注意
每次调用都产生费用(每次路线查询 0.008 美元),以 Base 上的 USDC 结算,需确保钱包有余额并限制支出。支付信息会经过第三方结算服务(Coinbase CDP、PayAI)。该服务器只返回路线信息,不执行桥接,但返回的步骤在执行前应人工核对。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Cross-Chain Bridge Route API,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 SSE。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体,或 SourceWeft 对话中。智能体会读取该服务器的安装指南,先向你展示发布者、端点和登录方式,经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/io.github.Br0ski777%2Fbridge-routes/install.md,并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前,先告诉我它的发布者、端点和登录方式,等我确认。不要把 API 密钥写进命令或我会提交的文件;问我密钥应从哪里获取。

README

Cross-Chain Bridge Route API

[MCP Server] [x402] [License: MIT]

Best cross-chain bridge routes via LI.FI -- 60+ chains, 18+ bridges, fees and time compared. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "bridge-routes": {      "url": "https://bridge-routes.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl "https://bridge-routes.api.klymax402.com/api/route?fromChain=...&toChain=...&token=...&amount=..."# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

ToolMethodPathPriceDescription
bridge_find_best_routeGET/api/route$0.008Find the best cross-chain bridge route
bridge_find_best_routePOST/api/route$0.008Find the best cross-chain bridge route (POST variant)

bridge_find_best_route

Use this when you need to bridge tokens between different blockchains. Returns ranked bridge routes with fees and timing in JSON.

Parameters

NameTypeRequiredDescription
fromChainstringyesSource chain ID (1=Ethereum, 8453=Base, 42161=Arbitrum, 10=Optimism, 137=Polygon, 56=BSC, 43114=Avalanche)
toChainstringyesDestination chain ID (1=Ethereum, 8453=Base, 42161=Arbitrum, 10=Optimism, 137=Polygon, 56=BSC, 43114=Avalanche)
tokenstringyesToken symbol to bridge (e.g. USDC, USDT, ETH, WETH)
amountstringyesAmount in smallest unit (e.g. 1000000 for 1 USDC with 6 decimals, 1000000000000000000 for 1 ETH)
toTokenstringnoDestination token symbol if different from source (optional, defaults to same as token)

Returns

  • routes -- array of bridge options ranked by best value
  • bridgeProvider -- which bridge protocol (Stargate, Across, Hop, Connext, etc.)
  • estimatedTime -- expected bridge completion time in seconds
  • fee -- total bridging fee in USD
  • amountReceived -- expected output amount on destination chain
  • steps -- detailed step-by-step route (approve, bridge, swap if needed)

Example response:

json
{"routes":[{"bridgeProvider":"Stargate","estimatedTime":60,"fee":0.85,"amountReceived":"999.15","steps":["approve USDC","bridge via Stargate"]}],"fromChain":"Ethereum","toChain":"Base","token":"USDC"}

When to use: moving assets cross-chain to find the cheapest and fastest bridge. Essential for multi-chain portfolio management.

Not for: gas prices (use gas_get_current_price).

bridge_find_best_route

Use this when you need to bridge tokens between different blockchains. Returns ranked bridge routes with fees and timing in JSON. POST variant of bridge_find_best_route -- same params passed as JSON body instead of query string.
