- On-chain product and batch ID verification (tamper-proof on Polygon)
- Full supply chain event timeline (GS1 EPCIS compatible)
- Certificate verification with IPFS-stored documents
- Bill of Materials (BOM) lineage with merge/split relations
- Zero gas cost for all read operations

Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

  1. Download and install Highlight from highlightai.com/download
  2. Navigate to the plugins tab and select "Add Custom Plugin"
  3. Configure the plugin with the settings below
    Plugin Name HimiTrace
    Command (node, npx, python, etc.)

    Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.

  4. Enable "Start Automatically" if you want the plugin to start when Highlight launches

From the repository

Install Node.js 20+ and npm, clone the repository, run npm install and npm run build, then test the connection with npm run test:local. Configure your MCP-compatible client (Claude Desktop, Cursor, Windsurf) by adding a command entry pointing to the compiled dist/index.js file. The server exposes tools that AI agents can call in plain language.

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.

HimiTrace MCP Server — Blockchain Product Traceability for AI Agents (TypeScript Port)

Polygon Mainnet
Model Context Protocol
Node.js

HimiTrace is a Model Context Protocol (MCP) server that connects AI agents directly to the Polygon Mainnet blockchain to check product authenticity, verify origins, and inspect supply chain event lineages. Developed by HimiTek (himitek.com), it bridges immutable on-chain trust data with natural language queries for AI agents.

This allows any MCP-compatible AI agent (such as Claude Desktop, Cursor, Windsurf, or ChatGPT) to query, track, and audit physical goods on-chain in plain language.

Key Features

- On-Chain Verification: Verify if a product or batch ID is registered on the Polygon blockchain (tamper-proof, immutable).
- Supply Chain Timeline (GS1 EPCIS compatible): Retrieve the full chronological event log of a product (harvesting, processing, packaging, shipping) directly from Polygon.
- Certificate Verification: Access quality certificates (USDA Organic, VietGAP, Fair Trade, etc.) stored on IPFS with their hashes anchored on-chain.
- BOM (Bill of Materials) Lineage: Trace parent-child merge/split relationships of raw material batches.
- Zero Gas Cost: All read operations from the smart contract are 100% free and do not require any crypto tokens (POL) to be spent by the AI agent.

Technical Specifications

- Contract Address: 0xFF7A3429427aFda56b2994B2F3eeF4464b851EE0
- Network: Polygon Mainnet (Chain ID: 137)
- Framework: built on Anthropic's Model Context Protocol (MCP) SDK using TypeScript and ethers.js (v6).

Installation & Setup

1. Prerequisites

- Node.js v20 or higher - npm

2. Install Dependencies

Clone the repository and install the packages:
npm install

3. Build the Project

Compile TypeScript to Javascript:
npm run build

4. Test Connection

Ensure that the server can connect to the Polygon contract and query tools locally:
npm run test:local
If you see ALL TESTS PASSED, your environment is configured correctly.

Connecting to AI Clients

1. Claude Desktop

Add HimiTrace MCP to your Claude Desktop configuration file.

- Windows: %APPDATA%\Claude\claude_desktop_config.json
- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Add the following to the mcpServers object:

{
"mcpServers": {
"himitrace-mcp": {
"command": "node",
"args": [
"C:/path/to/your/himitrace-mcp/dist/index.js"
]
}
}
}

Note: Make sure to replace C:/path/to/your/himitrace-mcp/dist/index.js with the actual absolute path to your compiled entry point.

2. Cursor or Windsurf IDE

In Cursor settings: 1. Go to Settings > Features > MCP. 2. Click + Add New MCP Server. 3. Fill in the fields: - Name: HimiTrace - Type: command - Command: node "C:/path/to/your/himitrace-mcp/dist/index.js"

Available Tools

AI agents can execute the following tools:

1. verify_product

Checks if a product exists on-chain and retrieves its registration parameters. - Argument: product_id (string, e.g., LOT-20260315-A1B2C3) - Returns: JSON containing verification status, name, origin, owner, registration date, and explorer links.

2. get_trace_history

Retrieves the complete supply chain history (timeline) of a product. - Argument: product_id (string) - Returns: Chronological array of events, including event types, timestamps, custom payload data (GS1 EPCIS standard), and the recorder's blockchain wallet address.

3. get_certificates

Retrieves certificates attached to a product. - Argument: product_id (string) - Returns: Lists certificate types, issuers, dates of issue/expiration, and secure IPFS gateway links.

4. get_batch_lineage

Traces the Bill of Materials (BOM) lineage (splits and merges of batches). - Argument: batch_id (string) - Returns: Parent-child relationships, quantities, and units of raw material inputs.

5. check_product_exists

Quick check for product presence. - Argument: product_id (string) - Returns: True/False status.

6. get_system_stats

Provides overall system statistics. - Returns: Registered products count, contract details, and wallet balance.

---

Available Resources

AI agents can reference the following static resources:

- himitrace://info: General system documentation, compliant industries, and standards.
- himitrace://contract: Blockchain metadata (chain_id, RPC node, contract code version).
- himitrace://pricing: Pricing tiers for API limits (Free, Pro, Enterprise).
