name: scp-regionalgeotime description: Use when you need to connect to the SciGraph SCP server for RegionalGeoTime (regional geologic time standards knowledge graph integrating 17 regional standards with the international time scale) 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-RegionalGeoTime (SciGraph) MCP client

What this SCP is

The Regional Geologic Time Standards Knowledge Graph is a machine-readable knowledge graph representing geologic time intervals (Epoch/Age) from 17 regional standards worldwide, integrated with the international geologic time scale. It supports automated data integration, semantic interoperability, and data-driven discovery in Earth science, especially for deep-time studies (geosphere/biosphere co-evolution).

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 (RegionalGeoTime):

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

get_kg_statistics

Return graph statistics.

Example arguments:

{ "kg_name": "RegionalGeoTime" }

get_entity_details

Return entity details.

Example arguments:

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

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