SCP-OceanGraph (SciGraph) MCP client

What this SCP is

OceanGraph (Historical Marine Biodiversity Knowledge Graph, a.k.a. OceanGraphRAG KG) is a domain knowledge graph for historical marine biodiversity records. The page describes it as developed by Gustavo Marcelo Núñez (independent researcher) and built using Microsoft’s GraphRAG framework to digitize and structure mid-20th-century South American (especially Argentine) literature about marine mammals, seabirds, and resource utilization, enabling natural-language retrieval and analysis.

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 (OceanGraph):

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

get_kg_statistics

Return graph statistics.

Example arguments:

{ "kg_name": "OceanGraph" }

get_entity_details

Return entity details.

Example arguments:

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

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