Agent Gateway Service

The Agent Gateway Service (AGW) is the central communication hub for SAP BTP agents. It supports two integration protocols: MCP for discovering and calling tools exposed by connected SAP LoB systems such as SAP S/4HANA and SAP SuccessFactors, and A2A (Agent-to-Agent) for discovering remote agents and delegating tasks to them.

LangChain Integration

Convert MCP tools to LangChain StructuredTool objects for use with LangChain agents:

from sap_cloud_sdk.agentgateway import create_client
from sap_cloud_sdk.agentgateway.converters import mcp_tool_to_langchain

agw_client = create_client(tenant_subdomain="my-tenant")
tools = await agw_client.list_mcp_tools(user_token="user-jwt")

langchain_tools = [
    mcp_tool_to_langchain(
        t,
        agw_client.call_mcp_tool,
        get_user_token=lambda: request.headers["Authorization"],
    )
    for t in tools
]

# Use with LangChain agent
llm_with_tools = llm.bind_tools(langchain_tools)

For the complete API reference and more examples, see the Agent Gateway user guide in the cloud-sdk-python repository.
