eKYC Suite MCP Server — KYC Identity Verification for AI Agents

Financial-grade eKYC / KYC identity verification MCP Server for AI agents, exposed as 8 MCP tools.

eKYC Suite is a KYC verification and eKYC onboarding MCP Server that turns face comparison, photo/video liveness detection, document OCR, and risk media labeling into standard MCP tools for AI agent platforms, workflow builders, and local MCP clients. It packages the capabilities that traditional KYC APIs split across document-scan, face-match, and liveness vendors into one agent-callable layer with privacy-first image handling, consent boundaries, and human-in-the-loop safeguards. Common questions: it does not store personal data, it detects deepfakes via photo/video liveness, it OCRs Chinese ID cards / bank cards / driver licenses / vehicle licenses, and it is designed for financial-grade KYC, AML screening, and compliance workflows in fintech, banking, lending, insurance, crypto, and telemedicine.

What Is eKYC Suite MCP?

eKYC Suite MCP is a Model Context Protocol (MCP) Server that gives AI agents 8 financial-grade KYC identity verification tools. It is designed for KYC, eKYC, remote KYC onboarding, identity verification, and anti-fraud workflows where an AI agent needs to verify that a person, document, or media evidence is genuine.

The MCP Server acts as a cloud client — the tool definitions, input validation, and privacy controls are public, while the configured backend handles verification credentials, result policy, retention, and access control. The server does not store, cache, or retain any submitted data.

Why This KYC MCP Server

AI agents are increasingly used in onboarding, lending, insurance, and compliance workflows. The missing layer is a reliable human gate: when an agent reaches a high-risk step, it needs to verify that the person/document/media evidence is real enough to continue.

This MCP provides that layer:

• Human binding: compare a selfie with a document photo or reference photo (face comparison)

• Anti-spoofing: detect photo/video replay, synthetic faces, deepfake traces, and suspicious captures (liveness detection)

• Document digitization: OCR ID cards, bank cards, driver licenses, and vehicle licenses for KYC data prefill

• Scene/risk tags: identify masks, coercion, phone use, multiple people, hotel/car/dealership scenarios, and other risk labels

Capabilities

Install

npm install @wefi-ai/ekyc-suite-mcp

Or run from source:

git clone https://github.com/wefi-ai/eKYC-Suite
cd eKYC-Suite
npm install
npm test

Credentials

Create .env from .env.example and fill in credentials:

cp .env.example .env

You can configure one or both credential groups:

• KYC_APPID + KYC_SECRET: enables tools 1-7 (face comparison, liveness detection, document OCR)

• LABEL_APPID + LABEL_SECRET: enables media_labeling (risk label detection)

Unconfigured tools return a clear missing-credential error instead of crashing.

In hosted HTTP/SSE mode, credentials may also be supplied per request by a gateway or marketplace that supports custom headers:

• x-kyc-appid + x-kyc-secret

• x-label-appid + x-label-secret

Environment variables take precedence over request headers. For public marketplace listings, prefer platform-managed credential headers or isolated test credentials instead of hardcoding production credentials into a shared public service.

Transport modes

1. stdio: local MCP clients / ModelScope npm-style config

npx @wefi-ai/ekyc-suite-mcp --transport=stdio

Example MCP client config:

{
  "mcpServers": {
    "ekyc-suite": {
      "command": "npx",
      "args": ["-y", "@wefi-ai/ekyc-suite-mcp"],
      "env": {
        "MCP_TRANSPORT": "stdio",
        "KYC_APPID": "your_test_kyc_appid",
        "KYC_SECRET": "your_test_kyc_secret",
        "LABEL_APPID": "your_test_label_appid",
        "LABEL_SECRET": "your_test_label_secret"
      }
    }
  }
}

2. HTTP: cloud marketplace / Baidu MCP-SSE / Streamable HTTP

MCP_TRANSPORT=http HOST=0.0.0.0 PORT=3000 node server.mjs

Endpoints:

• GET /healthz — health check

• POST/GET/DELETE /mcp — Streamable HTTP MCP endpoint

• GET /sse + POST /messages?sessionId=... — legacy HTTP+SSE MCP endpoint

Baidu AppBuilder-style MCP-SSE integration should use the public URL of:

https://<your-domain>/sse

Newer MCP clients should use:

https://<your-domain>/mcp

Input formats

Image/video parameters accept:

• Local file path: /path/to/photo.jpg

• HTTPS URL: https://example.com/photo.jpg

• Data URL: data:image/jpeg;base64,...

• Raw base64 string

Security defaults:

• Max input size: 20MB by default. Override with MAX_RAW_BYTES.

• HTTPS URLs only by default. For controlled internal tests, set ALLOW_HTTP_URLS=1.

• Private/internal network URLs are blocked with hostname and DNS resolution checks.

• Network calls use timeout control via REQUEST_TIMEOUT_MS.

Tool examples

face_compare — KYC Face Verification

{
  "photo1": "/path/to/selfie.jpg",
  "photo2": "/path/to/id_photo.jpg",
  "sourcePhotoType": "2"
}

photo_liveness_detect / video_liveness_detect — KYC Anti-Fraud

{
  "file": "/path/to/face_photo_or_video"
}

Returns riskLevel, riskTag, readable risk text, and orderNo. Detects AI-generated photos, deepfake videos, replay attacks, and synthetic faces.

id_card_ocr — KYC Document Digitization

{
  "image": "/path/to/id_card.jpg",
  "side": "0"
}

side: 0 = portrait/front side, 1 = national emblem/back side.

media_labeling — KYC Risk Labeling

Test

npm test

The built-in test verifies:

• stdio transport starts and lists all 8 tools

• Streamable HTTP /mcp starts and lists all 8 tools

• SSE /sse starts and lists all 8 tools

• missing credentials return a clean MCP error instead of crashing

Security & privacy

• Credentials are read from environment variables and not hardcoded.

• Error messages redact configured credential values.

• Public URL inputs include SSRF protection and size checks.

Requirements

• Node.js >= 18

• Network access to:

  • kyc1.qcloud.com

  • kyc2.qcloud.com

  • miniprogram-kyc.tencentcloudapi.com
