scp-healx

name	scp-healx
description	Use when you need to connect to the SciGraph SCP server for Healx (rare disease drug repositioning biomedical knowledge graph by Healx Ltd.) and call its MCP tools (query_cypher, get_kg_statistics, get_entity_details, get_experiment_workflow), including streamableHttp configuration with SCP-HUB-API-KEY and Python 3.10+ usage examples.

SCP-Healx (SciGraph) MCP client

What this SCP is

Healx KG is a multi-source integrated biomedical knowledge graph for rare disease drug repositioning (Healx Ltd.). It targets interpretable therapeutic hypotheses via symbolic reasoning and automated filtering, integrating public/commercial/internal data across compounds, diseases, genes, pathways, and pharmacological/genetic/clinical relationships.

Connection info

• MCP server URL:
  • https://scp.intern-ai.org.cn/api/v1/mcp/37/SciGraph
• Auth header:
  • SCP-HUB-API-KEY: {API-KEY}

Install

pip install mcp

Tools

query_cypher

Execute a Cypher query and return JSON results.

Arguments:

• cypher (string, required)
• kg_name (string|null, optional, default null)
• limit (int, optional, default 100)

Example arguments (Healx):

{
  "cypher": "MATCH (e:Experiment:Healx) RETURN e.id as experiment_id",
  "kg_name": "Healx",
  "limit": 5
}

get_kg_statistics

Return graph statistics.

Example arguments:

{ "kg_name": "Healx" }

get_entity_details

Return entity details.

Example arguments:

{ "entity_identifier": "experiment_1", "kg_name": "Healx" }

get_experiment_workflow

Return the full workflow of an experiment.

Example arguments:

{ "experiment_id": "experiment_1" }

Python example (streamable HTTP)

import asyncio
import json
from mcp.client.streamable_http import streamablehttp_client
from mcp.client.session import ClientSession

SERVER_URL = "https://scp.intern-ai.org.cn/api/v1/mcp/37/SciGraph"

async def main():
    transport = streamablehttp_client(
        url=SERVER_URL,
        headers={"SCP-HUB-API-KEY": "sk-xxx"},
    )
    read, write, get_session_id = await transport.__aenter__()

    session_ctx = ClientSession(read, write)
    session = await session_ctx.__aenter__()
    await session.initialize()

    # Example: stats for Healx
    result = await session.call_tool(
        "get_kg_statistics",
        arguments={"kg_name": "Healx"},
    )
    data = json.loads(result.content[0].text)
    print(data)

    await session_ctx.__aexit__(None, None, None)
    await transport.__aexit__(None, None, None)

if __name__ == "__main__":
    asyncio.run(main())
