MCP server for Sift — global ML fraud detection: real-time risk scoring, decisions, event ingestion

PopNx MCP 的三大支柱

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。

它能帮你做什么

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。

  • 连接方式: 在你的电脑上运行
  • 传输方式: stdio
  • 分类: 其他
  • 你需要填写：SIFT_API_KEY, SIFT_ACCOUNT_ID

安装

选择你使用的 AI 应用，然后复制设置。

安装之前

  • 基础检查：1 项中通过 1 项
  • 在你的电脑上运行，拥有你的用户账户的权限（文件、网络、应用）。
  • 需要你自己填写： SIFT_API_KEY, SIFT_ACCOUNT_ID, SIFT_BASE_URL

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。

你需要

  • npm已安装 Node.js（用于 npx 命令）

你用的是哪个应用？

在上方选择你的应用。我们会记住它，下次按钮会显示“安装到 …”。

打开 Claude Desktop → Settings → Developer → Edit Config，把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "sift": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-sift"
      ],
      "env": {
        "SIFT_API_KEY": "your-value",
        "SIFT_ACCOUNT_ID": "your-value",
        "SIFT_BASE_URL": "your-value"
      }
    }
  }
}

在终端中运行这条命令

claude mcp add sift --env SIFT_API_KEY=your-value --env SIFT_ACCOUNT_ID=your-value --env SIFT_BASE_URL=your-value -- npx -y @codespar/mcp-sift

运行前请先填写空着的值。

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json，或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "sift": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-sift"
      ],
      "env": {
        "SIFT_API_KEY": "your-value",
        "SIFT_ACCOUNT_ID": "your-value",
        "SIFT_BASE_URL": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用，然后应用会显示设置并请你确认。密钥的值会留空，由你自己填写。

在 VS Code 中打开

或者自己复制设置

粘贴到项目中的 .vscode/mcp.json

{
  "servers": {
    "sift": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-sift"
      ],
      "env": {
        "SIFT_API_KEY": "your-value",
        "SIFT_ACCOUNT_ID": "your-value",
        "SIFT_BASE_URL": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用，然后应用会显示设置并请你确认。密钥的值会留空，由你自己填写。

@codespar/mcp-sift

MCP server for Sift — global enterprise ML-based fraud detection.

Third entry in the CodeSpar fraud category after @codespar/mcp-clearsale and @codespar/mcp-konduto. Sift is the global / enterprise counterpart to the two BR-native antifraud servers.

Positioning

ClearSaleKondutoSift
GeographyBrazilBrazilGlobal (US-HQ, ~30 countries)
Founded200120142011
StrengthChargeback history dbBehavioral device intelligenceMulti-abuse-type ML + workflow decisions
ShapeScore + manual reviewAPI-first, tight surfaceEvent stream in, scores + decisions out
ScopeOrder fraudOrder fraudPayment, account, content, promotion abuse

Also distinct from @codespar/mcp-jumio, which is global KYC / identity verification — a different layer than fraud scoring.

Sift's API shape

Sift is built around three APIs that work together:

  1. Events API (/v205/events) — you POST every interesting signal (account creation, login, order, chargeback, ...) as a $-prefixed event.
  2. Score API (/v205/users/{user_id}/score) — you GET the latest ML score for a user, or POST to force a rescore. Scores are floats in [0, 1] per abuse type (payment_abuse, account_abuse, content_abuse, promotion_abuse).
  3. Decisions API v3 (/v3/accounts/{account_id}/...) — workflows in the Sift console turn scores into Decisions (block_user_payment_abuse, approve_order_payment_abuse, etc). You can apply a decision directly, read the current decisions on a user/order, or fetch the status of a workflow run.

Tools (20)

ToolPurpose
send_eventSend a fraud signal to Sift's Events API (POST /v205/events).
get_user_scoreFetch the latest Sift score(s) for a user (GET /v205/users/{user_id}/score).
rescore_userForce Sift to recompute a user's score right now (POST /v205/users/{user_id}/score).
label_userLabel a user as fraud or not-fraud via the legacy Labels API (POST /v205/users/{user_id}/labels).
unlabel_userRemove any existing label on a user (DELETE /v205/users/{user_id}/labels).
apply_decision_to_userApply a workflow Decision to a user (POST /v3/accounts/{account_id}/users/{user_id}/decisions).
apply_decision_to_orderApply a workflow Decision to a specific order (POST /v3/accounts/{account_id}/users/{user_id}/orders/{order...
get_user_decisionsFetch the decisions currently applied to a user (GET /v3/accounts/{account_id}/users/{user_id}/decisions).
get_order_decisionsFetch the decisions currently applied to an order (GET /v3/accounts/{account_id}/orders/{order_id}/decisions).
get_workflow_runFetch the status of a Sift Workflow run (GET /v3/accounts/{account_id}/workflows/runs/{run_id}).

Install

npm install @codespar/mcp-sift@alpha

Environment

SIFT_API_KEY="..."         # required, secret

SIFT_ACCOUNT_ID="..." # required for all Decisions API v3 calls SIFT_BASE_URL="..." # optional; defaults to https://api.sift.com

Authentication

  • Events API — $api_key is injected into the JSON body. The server handles this automatically.
  • Score API + Decisions API v3 — HTTP Basic, API key as username, empty password. The server handles the base64 encoding.

Pass the raw key in SIFT_API_KEY.

Typical flow

  1. Instrument your app: every signup, login, profile update, order, and chargeback becomes a send_event call with the right $type.
  2. On high-stakes moments (checkout, withdrawal), call send_event with return_score: true to get an inline decision.
  3. Or poll get_user_score / get_order_decisions asynchronously after a workflow run completes.
  4. For manual review outcomes, call apply_decision_to_user or apply_decision_to_order with a Decision ID configured in the Sift console and source: "MANUAL_REVIEW".
  5. When a chargeback is confirmed, send a $chargeback event AND either apply_decision_to_user with a Block decision or label_user with is_bad: true, abuse_type: "payment_abuse". Decisions are preferred for new integrations; Labels are kept for backward compatibility.

Alpha note

Shipped as 0.1.0-alpha.1. All endpoint paths are verified against Sift's official Ruby SDK (SiftScience/sift-ruby): rest_api_path, user_score_api_path, users_label_api_path, user_decisions_api_path, order_decisions_api_path, workflow_status_path, and the Decision ApplyTo path builder.

Scope vs. the original brief:

  • Shipped & verified: send_event, get_user_score, rescore_user, label_user, unlabel_user, apply_decision_to_user, apply_decision_to_order, get_user_decisions, get_order_decisions, get_workflow_run.
  • Dropped — not in the public SDK:
  • get_session_score (/v205/sessions/{session_id}/score) — no equivalent helper in the Ruby SDK; session-level scoring in Sift flows through session-level Decisions and Workflow runs, not a dedicated score endpoint.
  • list_workflow_runs (GET /v3/accounts/{account_id}/workflows/runs) — only GET /{run_id} is implemented in the public SDK. In practice, Sift surfaces run_ids in event responses rather than via a list endpoint.
  • get_psychology_score — no such endpoint in the public SDK.

The developers.sift.com reference pages gate deep-link URLs (403 on several paths), so we used the official SDK as the source of truth. Promote to 0.1.0 once a customer confirms (or denies) the dropped endpoints against the full Decisions / Score API reference in Sift's admin console.

Run

# stdio (default — for Claude Desktop, Cursor, etc)

npx @codespar/mcp-sift

HTTP (for server-to-server testing)

MCP_HTTP=true MCP_PORT=3000 npx @codespar/mcp-sift

Category

fraud — third entry after ClearSale and Konduto. BR merchants operating internationally commonly pair Sift (global payment/account abuse) with ClearSale or Konduto (BR-specific chargeback history / device intelligence).

Enterprise

Need governance, budget limits, and audit trails for agent payments? CodeSpar Enterprise adds policy engine, payment routing, and compliance templates on top of these MCP servers.
