The Breakthrough

Until now, Claude Code couldn’t connect to SAP AI Core because it requires Anthropic’s specific /v1/messages API format. The missing piece was a bridge that could translate between SAP AI Core’s API and what Claude Code expects.

That bridge now exists.

Quick Setup Guide

1. Get the Proxy

git clone https://github.com/pjq/sap-ai-core-llm-proxy.git
cd sap-ai-core-llm-proxy
pip install -r requirements.txt

2. Configure SAP AI Core SDK (Recommended Method)

The proxy is using sap-ai-sdk-gen Python SDK, you can read the document to get more configuration details.

SAP AI Core SDK Guideline

First, create the AI Core configuration directory:

mkdir -p ~/.aicore

Then create ~/.aicore/config.json with your SAP AI Core credentials:

{
  "AICORE_AUTH_URL": "https://*****.authentication.sap.hana.ondemand.com",
  "AICORE_CLIENT_ID": "*****",
  "AICORE_CLIENT_SECRET": "*****",
  "AICORE_RESOURCE_GROUP": "*****",
  "AICORE_BASE_URL": "https://api.ai.*****.cfapps.sap.hana.ondemand.com/v2"
}

Replace the ***** placeholders with your actual SAP AI Core service credentials from your service key.

3. Configure the AI Core Proxy Server

Copy and edit the main configuration:

cp config.json.example config.json

Set up your SAP AI Core deployments:

{
    "subAccounts": {
        "production": {
            "resource_group": "default",
            "service_key_json": "sap-ai-core-key.json",
            "deployment_models": {
                "anthropic--claude-4-sonnet": [
                    "https://api.ai.intprod-eu12.eu-central-1.aws.ml.hana.ondemand.com/v2/inference/deployments/your-deployment-id"
                ]
            }
        }
    },
    "secret_authentication_tokens": ["your-secret-token"],
    "port": 3001
}

And make sure you have already downloaded the service key json sap-ai-core-key.json

4. Start the Proxy

python proxy_server.py --config config.json --debug

5. Configure Claude Code Environment

export ANTHROPIC_AUTH_TOKEN=your-secret-token
export ANTHROPIC_BASE_URL=http://127.0.0.1:3001
export ANTHROPIC_MODEL=anthropic--claude-4-sonnet

6. Launch Claude Code
