mcp-probot-hdi

An MCP (Model Context Protocol) server for querying herb-drug and drug-drug interactions from the Probot HDI database.

The server speaks MCP over stdio and forwards tool calls to the Cancer Probot HTTP MCP API (POST with JSON body and Authorization: Bearer).

Installation

npm install -g @kinginsun/mcp-probot-hdi

Configuration

Token (required)

Create a personal API token in your Cancer Probot account (user center). The plaintext value starts with pb- and is shown only once when created.

Set it via:

export PROBOT_MCP_TOKEN=pb-your_token_here

The server sends this value as the HTTP header Authorization: Bearer <token>. Tokens must start with pb-; other values are rejected at startup.

API base URL (optional)

By default requests go to https://cancer.probot.hk/probot_api/mcp (no trailing slash). Override if you need another deployment:

export PROBOT_HDI_API_BASE=https://example.com/probot_api/mcp

Cursor / Claude Desktop

Add to your MCP configuration:

{
  "mcpServers": {
    "probot-hdi": {
      "command": "npx",
      "args": ["@kinginsun/mcp-probot-hdi"],
      "env": {
        "PROBOT_MCP_TOKEN": "pb-your_token_here"
      }
    }
  }
}

Tools

probot-hdi

Search herb-drug or drug-drug interactions by drug/herb names.

Parameter	Type	Required	Description
drug1	string	Yes	Drug/herb name, or multiple aliases in one string separated by ASCII | (see JSON examples)
drug2	string	No	Second drug/herb; same pipe-separated alias convention
maxRows	number	No	Maximum results to return (default: 10)

When only drug1 is provided, the API returns all known interactions involving that item (up to maxRows).

Example:

{
  "name": "probot-hdi",
  "arguments": {
    "drug1": "aspirin|阿司匹林|乙酰水杨酸",
    "drug2": "ginkgo biloba"
  }
}

probot-search-item

Look up a drug or herb by name and return its item_id. Use this to resolve drug/herb names to unique identifiers before querying interactions by ID.

Parameter	Type	Required	Description
drug	string	Yes	Drug/herb name, or multiple aliases separated by |

Example:

{
  "name": "probot-search-item",
  "arguments": {
    "drug": "aspirin|阿司匹林"
  }
}

probot-hdi-by-id

Search herb-drug or drug-drug interactions by item_id(s) obtained from probot-search-item.

Parameter	Type	Required	Description
item_id1	string	Yes	First item_id
item_id2	string	No	Second item_id
maxRows	number	No	Maximum results to return (default: 10)

When only item_id1 is provided, the API returns all known interactions for that item (up to maxRows).

Example:

{
  "name": "probot-hdi-by-id",
  "arguments": {
    "item_id1": "123",
    "item_id2": "456"
  }
}

Typical Workflow

1. Direct query — Use probot-hdi with drug names for a quick one-step lookup.
2. Two-step query — Use probot-search-item to resolve names to item_id, then use probot-hdi-by-id for precise interaction queries. This is useful when you need to verify which drug was matched or reuse the same ID across multiple queries.

Requirements

• Node.js >= 18.0.0
• A valid personal token (pb-…) in PROBOT_MCP_TOKEN
