Sap Hana

A Model Context Protocol (MCP) server for SAP HANA, built with FastMCP and the official SAP HANA Python driver (hdbcli).

This server exposes SAP HANA database capabilities (listing tables, columns, running queries) as MCP tools that AI assistants can use.

Prerequisites

• Python 3.12+
• Access to a SAP HANA instance (on-premise or SAP HANA Cloud)
• SAP HANA client libraries (installed automatically with hdbcli)

Installation

# Clone and enter the directory
cd sap-hana-mcp-server-python

# Install dependencies
pip install -r requirements.txt

Configuration

Copy the example environment file and fill in your SAP HANA connection details:

cp .env.example .env

Edit .env with your server settings:

Variable	Description	Default
HANA_HOST	SAP HANA server hostname	(required)
HANA_PORT	SAP HANA server port	443
HANA_SCHEMA	Default schema to filter tables	(optional)
SERVER_PORT	MCP server HTTP port	8000

Authentication

SAP HANA credentials are provided by each MCP client via HTTP Basic Auth. The server does not store database credentials — each request must include an Authorization header with the user's SAP HANA username and password.

Authorization: Basic <base64(username:password)>

If the header is missing or invalid, the server returns an error. This allows different users to connect with their own SAP HANA accounts.

Running the Server

Locally

python main.py

The server starts on http://localhost:8000/sse using SSE transport.

With Docker

docker build -t sap-hana-mcp .
docker run -p 8000:8000 --env-file .env sap-hana-mcp

MCP Tools

sap_hana_get_tables

Lists tables available in the SAP HANA instance. Returns CSV with columns: Schema, Table, Description.

Parameter	Type	Required	Description
catalog	string	No	Catalog name filter
schema	string	No	Schema name filter (defaults to HANA_SCHEMA)

sap_hana_get_columns

Lists columns for a specific table. Returns CSV with columns: Schema, Table, Column, DataType, Remarks.

Parameter	Type	Required	Description
table	string	Yes	Table name
catalog	string	No	Catalog name filter
schema	string	No	Schema name filter (defaults to HANA_SCHEMA)

sap_hana_run_query

Executes a SQL SELECT statement. Returns results in CSV format. The SQL dialect is based on SQL-92. Identifiers should be quoted with double quotes.

Parameter	Type	Required	Description
sql	string	Yes	The SELECT statement to execute

sap_hana_lookup_table_info

Looks up SAP table and field descriptions from leanx.eu. Useful when the SAP HANA system catalog has no comments or descriptions for tables and columns. Does not require database authentication.

Parameter	Type	Required	Description
table	string	Yes	SAP table name (e.g. ANLA, BKPF, MARA)

Returns CSV with columns: Field, Description, DataElement, Datatype, Length, Decimals.

MCP Resources

sap_hana://tables/{schema}/{table}

Returns column metadata for a given schema and table in CSV format.

Connecting to AI Clients

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "sap-hana": {
      "url": "http://localhost:8000/sse",
      "headers": {
        "Authorization": "Basic <base64(username:password)>"
      }
    }
  }
}

Cursor / Other MCP Clients

Use the SSE endpoint http://localhost:8000/sse and configure the Authorization: Basic header with your SAP HANA credentials.
