Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
作者提供的说明(英文原文)
Fetch any public URL as a visitor in a chosen country, with a signed receipt of its origin.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
REGION_FETCH_WALLET_PRIVATE_KEY, REGION_FETCH_MAX_PAYMENT, REGION_FETCH_BASE_URL, REGION_FETCH_PAYMENT_SIGNATURE标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"regionfetch": {
"command": "npx",
"args": [
"-y",
"regionfetch-mcp"
],
"env": {
"REGION_FETCH_WALLET_PRIVATE_KEY": "your-value",
"REGION_FETCH_MAX_PAYMENT": "your-value",
"REGION_FETCH_BASE_URL": "your-value",
"REGION_FETCH_PAYMENT_SIGNATURE": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add regionfetch --env REGION_FETCH_WALLET_PRIVATE_KEY=your-value --env REGION_FETCH_MAX_PAYMENT=your-value --env REGION_FETCH_BASE_URL=your-value --env REGION_FETCH_PAYMENT_SIGNATURE=your-value -- npx -y regionfetch-mcp运行前请先填写空着的值。

MCP server for Region Fetch — fetch a public HTTPS URL as a visitor in a specific country would see it, with a signed Ed25519 receipt proving where the retrieval came from.
Pre-release. Not yet published to npm. Build from source:
npx -y regionfetch-mcp
Node 20.11+. stdio transport. Exposes exactly one tool: regionfetch.
{
"mcpServers": { "regionfetch": { "command": "npx", "args": ["-y", "regionfetch-mcp"], "env": { "REGION_FETCH_BASE_URL": "https://regionfetch.dev", "REGION_FETCH_WALLET_PRIVATE_KEY": "0x...", "REGION_FETCH_MAX_PAYMENT": "$0.10" } } } }
The server signs one fresh x402 authorization per tool call. This is the only configuration that keeps working past the first request.
"env": { "REGION_FETCH_PAYMENT_SIGNATURE": "<one x402 authorization>" }
One authorization funds one request, so the second tool call will fail. The server says so on stderr at startup. Useful for a one-shot compatibility check, not for a running server.
Wallet mode wins when both are configured.
| Variable | Default | Purpose |
|---|---|---|
REGION_FETCH_BASE_URL | https://regionfetch.dev | Deployment origin. A trailing /api is stripped. |
REGION_FETCH_WALLET_PRIVATE_KEY | — | Funded Base wallet key. Enables wallet mode. |
REGION_FETCH_MAX_PAYMENT | $0.10 | Per-payment ceiling. off disables it. |
REGION_FETCH_PAYMENT_SIGNATURE | — | A single pre-made authorization. |
REGION_FETCH_RPC_URL | — | RPC endpoint for on-chain reads during payment construction. |
REGION_FETCH_TIMEOUT_MS | 120000 | Per-request timeout. |
REGION_FETCH_ALLOW_INSECURE_HTTP | 0 | Permit an http:// base URL. Development only. |
Legacy GEOFETCH_BASE_URL, GEOFETCH_PAYMENT_SIGNATURE, and PAYMENT_SIGNATURE are still read, with the canonical names taking precedence. Their use is reported as deprecated on stderr.
`regionfetch` — url (https, ≤ 2048 chars), country (US | DE | JP | BR | IN), mode (http | browser, default http).
Results use the v1 envelope:
{
"status": 200, "ok": true, "response": { "data": { "...": "..." }, "receipt": { "...": "..." } }, "verification": { "valid": true, "signatureValid": true, "bodyHashMatches": true } }
verification is an additive field: the server verifies each receipt against the deployment's published key and the returned body before handing it to the model. Consumers reading only status, ok, and response are unaffected.
Non-2xx responses keep the upstream status and JSON body verbatim and set isError: true. Terminal paid failures (502, 504) keep their signed receipts — they are the evidence the paid attempt happened.
tools capability is advertised. No resources, prompts, or subscriptions are implemented or claimed.Full documentation: https://github.com/regionfetch/regionfetch
