SCP-KG-MTL (SciGraph) MCP client

What this SCP is

KG-MTL is a knowledge graph enhanced multi-task learning framework for molecular interaction prediction. It integrates biomedical knowledge graphs with molecular graph representations to jointly learn semantic relations and molecular structures, improving prediction of drug–target interactions (DTI) and compound–protein interactions (CPI).

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 (KG-MTL):

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

get_kg_statistics

Return graph statistics.

Example arguments:

{ "kg_name": "KG-MTL" }

get_entity_details

Return entity details.

Example arguments:

{ "entity_identifier": "experiment_1", "kg_name": "KG-MTL" }

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 KG-MTL
    result = await session.call_tool(
        "get_kg_statistics",
        arguments={"kg_name": "KG-MTL"},
    )
    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())
