About this project
This is a protocol adapter for the Model Context Protocol to expose CAP services for agent consumption. For more information, check the official documentation.
[!IMPORTANT] SAP API Policy Applies
The SAP API Policy remains applicable even when exposing data via MCP. Before exposing any SAP service or data through an MCP endpoint, ensure your use case complies with the SAP API Policy and any applicable licensing terms.
Feature Flags
All configuration lives under cds.mcp in your package.json:
{
"cds": {
"mcp": {
"per_action_tool": false,
"prefix": false,
"format": "cql"
}
}
}
| Flag | Default | Description |
|---|---|---|
per_action_tool | false | Expose each action/function as its own dedicated tool instead of the generic call tool. |
prefix | false | Prefix tool names with the service name to avoid collisions when a MCP client connects to multiple MCP servers (e.g. CatalogService-query, AdminService-query). |
format | "cql" | Change the query input format. "cqn" uses structured CQN input. "cql" uses CQL SELECT statement |
For all other configuration options, refer to the official documentation.
Custom Server Instructions
You can customize the MCP server instructions sent to agents during initialization using the @mcp.instructions annotation:
annotate MyService with @mcp.instructions: 'Use describe to explore the product catalog. Use query to search products by name or category.';
If not set, a default instruction is used. The annotation also supports i18n references ({i18n>key}).
