Exposing APIs to AI agents without Integration Suite? MCP on CAP?
Everything SAP publishes on agent integration assumes you have the MCP Gateway, which means Integration Suite Premium or Enhanced. Plenty of customers don't have that entitlement and won't buy it for a pilot.
What I've looked at:
- Own MCP server calling published OData. RA0029 sanctions an external MCP server, so this seems allowed. You just own all the auth and hardening yourself.
- RAP or SEGW in the ABAP stack. Cleanest curated layer, but only permitted on Private Cloud and on-prem.
- CAP with u/cap-js
/mcp**.** Great DX, but Developer License 3.2 limits productive use to BTP or another SAP-licensed platform. Anyone got a straight answer on that?
Where I'm stuck: per-user identity. The Gateway has a documented IdP user token model. Without it you're building SAML bearer assertion or principal propagation yourself. Anyone done this against Public Cloud or other SAP products, and did you need Cloud Identity Services in the path?
Not looking for "just buy Integration Suite", curious what people are actually running without it.
