BTP Audit Log MCP Server: Security Monitoring with AI AssistantsBTP Audit Log MCP Server: Security Monitoring with AI AssistantsWouter Lemaire builds an MCP server over SAP BTP's Audit Log Retrieval API using odata-mcp-proxy, with a single entity set and zero custom code, so an AI assistant can answer natural-language questions like "Were there any configuration changes yesterday?" by calling AuditLogRecords_list against a BTP destination authenticated with the Audit Log service's service key. It covers the destination setup, the entity-set configuration that maps the PascalCase entity name to a lowercase auditlogrecords path, and handling the API's 500-record pagination limit.published 2026-03-13
CAP: The Road Ahead - Simplicity in an AI EraCAP: The Road Ahead - Simplicity in an AI EraDevtoberfest 2026 session CAP10, from the head of SAP's Cloud Application Programming Model: forty minutes of live building rather than slides, on the argument that the cheapest code in an AI project is code nobody has to generate. Claude Code builds an invoice-matching workspace from cds init onwards, and each step is one the framework answers rather than the agent: a 42-line domain model that @sap/cds serves as OData and Fiori elements with a status flow, data privacy and change-tracking annotations that produce audit log entries in the console and would reach the SAP Audit Log service once deployed, an imported S/4HANA supplier data product, and semantic matching from a local embedding model after @cap-js/ai is added. The last three steps are annotations: @mcp beside @odata turns the service into an MCP server that a second Claude session queries through @cap-js/mcp, an agent annotation adds the A2A protocol with an agent card and an audit log entry for the agent task, and a skill file gives the agent the matching policy.SAP Developers, published 2026-09-25
How to enable SAP Audit Log Viewer service to collect all Audit logs from BTP Services - Part 1How to enable SAP Audit Log Viewer service to collect all Audit logs from BTP Services - Part 1Walks through subscribing to the SAP Audit Log service's viewer app from the SAP BTP cockpit and creating a RoleCollection from the auditlog-management and auditlog-viewer role templates, assigned to a user or by a rule on the IDP's SAML assertion, to read audit logging events in a subaccount. The post's own update notes that a BTP release from 19 February 2026 removed the need for that role-assignment step. It also lists which Cloud Foundry services write audit log events, pointing to each service's own auditing page rather than detailing them here.Yogananda, published 2025-03-07

Introducing the Cloud Application Programming Model (CAP)Introducing the Cloud Application Programming Model (CAP)SAP's own general-availability announcement for CAP, laid out as a Golden Path: a data model and service defined in CDS gets a generated service provider that serves metadata publishing and CRUD requests, fills in primary keys and audit data, and writes trace and audit logs without application code. The same CDS model carries annotations that translate to OData vocabularies and generate a Fiori elements app skeleton, which is how Fiori annotations work in CAP.Daniel7, published 2018-06-05
Nice patch SAP! Revisiting your SAP BTP security measures after AI Core vulnerability fixNice patch SAP! Revisiting your SAP BTP security measures after AI Core vulnerability fixWritten after the SAPwned disclosure in SAP AI Core, it argues SAP BTP's shared-responsibility model still requires the customer's own hardening: scope SAP BTP, Cloud Foundry Runtime and SAP BTP, Kyma runtime app access, rotate OAuth2 client-credentials secrets, and enforce MFA and Conditional Access through a corporate identity provider rather than relying on SAP's patch alone. It then explains how the SAP Audit Log service writes standardized events for most Cloud Foundry BTP services, and walks through onboarding a BTP subaccount into Microsoft Sentinel for SAP BTP to query those logs with Kusto and build detection rules that flag unexpected login countries or known-bad IPs and trigger automatic user blocks.published 2024-07-25

CAP for nodejs安全的暴露接口练习CAP for nodejs安全的暴露接口练习Starting from the risk-management sample, the walkthrough adds an open ExternalAPI service beside the existing RiskService, then moves every security annotation into a separate service-auth.cds file: @requires: authenticated-user on one entity, role-scoped @restrict grants for RiskViewer and RiskManager on another. It tests the unprotected action locally with cds watch, calling it from Postman with the session cookie read out of SAP Business Application Studio's preview tab. It then deploys to BTP and reads Risks with a client-credentials OAuth token fetched from a service key of the cpapp-auth instance, after changing that entity's READ grant from RiskViewer to authenticated-user, which the post, citing capire's CDS-based Authorization page, describes as a grant for a technical user integrating systems rather than for access from a front end.ArthurYang, published 2024-12-10

How SAP secures enterprise AI agents with identity propagationHow SAP secures enterprise AI agents with identity propagationCloud Identity Services as the identity layer for AI agents as well as people: the abstract states that both are managed in one directory, that user context is propagated by token exchange, and that authorisation is enforced at every hop, so no agent holds back-end credentials. Agents from Microsoft, Google and partners take the same flow through the agent gateway. Token exchange across a hop is the authentication side and the per-hop check the authorisation side; what the agent gateway is, and whether it is a product, the abstract does not say.

Integrating and Extending JouleIntegrating and Extending JouleSAP's reference architecture for SAP Joule across SAP cloud applications: a request is checked against a Scenario Catalog of the applications' skills and a Knowledge Catalog answered by retrieval-augmented generation, combined with the user's roles and history, sent to an LLM available through the generative AI hub, and, where a Joule function is needed, turned into a call to the backend. Its identity page is the authentication path: each user sits in the Identity Directory of Cloud Identity Services with a Global User ID, Identity Provisioning synchronises role assignments into SAP Build Work Zone, whose navigation service decides which functions a user may call, and the Destination service exchanges the user's token to call a function in the user's name. Its extension page covers Joule Studio in SAP Build, where Joule skills automate rule-based tasks over APIs and AI agents plan and reason with models and document grounding from SAP AI Core, the ground agent tooling covers; a later Joule Studio page describes a managed Joule Studio Runtime on the SAP Business AI Platform, which has no entry here.published 2026-03-16

Because agent, servers and APIs share one XSUAA tenant, the chat service forwards the signed-in user's own JWT instead of a service account, so each downstream server enforces that user's own authorizations. Past roughly a hundred combined tools the single prompt slows down and stops separating concerns, which is why the author's next post splits it into one specialist agent per MCP server behind an orchestrator.published 2026-05-03

CAP for nodejs安全的暴露接口练习CAP for nodejs安全的暴露接口练习Starting from the risk-management sample, the walkthrough adds an open ExternalAPI service beside the existing RiskService, then moves every security annotation into a separate service-auth.cds file: @requires: authenticated-user on one entity, role-scoped @restrict grants for RiskViewer and RiskManager on another. It tests the unprotected action locally with cds watch, calling it from Postman with the session cookie read out of SAP Business Application Studio's preview tab. It then deploys to BTP and reads Risks with a client-credentials OAuth token fetched from a service key of the cpapp-auth instance, after changing that entity's READ grant from RiskViewer to authenticated-user, which the post, citing capire's CDS-based Authorization page, describes as a grant for a technical user integrating systems rather than for access from a front end.ArthurYang, published 2024-12-10

Dynamic authorisation with user attributes in SAP CAP and AMSDynamic authorisation with user attributes in SAP CAP and AMSThe same argument as the XSUAA-to-AMS piece, opened from a concrete failure: an acquisition puts 500 users on sales data restricted by division, and role-based access control answers it with Sales_Manager_EMEA, Sales_Manager_APAC and so on until the roles multiply past managing. Attribute-based authorisation replaces the set with one policy carrying a restriction, and the post walks through defining it in AMS against Cloud Identity Services.

How SAP secures enterprise AI agents with identity propagationHow SAP secures enterprise AI agents with identity propagationCloud Identity Services as the identity layer for AI agents as well as people: the abstract states that both are managed in one directory, that user context is propagated by token exchange, and that authorisation is enforced at every hop, so no agent holds back-end credentials. Agents from Microsoft, Google and partners take the same flow through the agent gateway. Token exchange across a hop is the authentication side and the per-hop check the authorisation side; what the agent gateway is, and whether it is a product, the abstract does not say.

Claude Code builds an invoice-matching workspace from cds init onwards, and each step is one the framework answers rather than the agent: a 42-line domain model that @sap/cds serves as OData and Fiori elements with a status flow, data privacy and change-tracking annotations that produce audit log entries in the console and would reach the SAP Audit Log service once deployed, an imported S/4HANA supplier data product, and semantic matching from a local embedding model after @cap-js/ai is added. The last three steps are annotations: @mcp beside @odata turns the service into an MCP server that a second Claude session queries through @cap-js/mcp, an agent annotation adds the A2A protocol with an agent card and an audit log entry for the agent task, and a skill file gives the agent the matching policy.SAP Developers, published 2026-09-25

It names four BTP services: SAP Personal Data Manager, SAP Data Retention Manager, SAP Data Privacy Integration and SAP Audit Log service. Only the first is described, as a service running in the Cloud Foundry environment that finds data subjects across one or more applications and services, makes requests on an individual's behalf about their personal information and forwards them for handling, and notifies individuals which of their personal information is being used or sends them a copy of their record by email; the CAP-side annotations and PDM's own application features follow in Part 2 and Part 3.Ajit_K_Panda, published 2023-03-18

Covers the xsuaa trust arrangement and service binding that let the standalone PDM application call back into the CAP service to read and manage that data.

PDM stores none of the personal data itself, only the requests and access logs, which an administrator downloads through the separate Data Transport app. It builds on the annotation model the first two parts introduce, so what it demonstrates is PDM's own delivered UI rather than anything a CAP application must build itself.Ajit_K_Panda, published 2023-03-18

CAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry: Engineering SAP CAP Applications from Business Intent with Guardrailed AICAP Foundry is a prototype that generates a CAP Node.js project with SAP Fiori elements from a written business requirement, discovering the actual data shape from a chosen source — SQLite, a configured SAP HANA HDI container, offline EDMX, live OData through the SAP Destination service, or approved SAP BTP ABAP objects — instead of inventing one. The generated application can carry a Fiori draft lifecycle with optimistic concurrency via ETags and annotation-driven Fiori elements list and object screens, localized independently of the underlying service contract. Attachments can be added with upload, download and delete, gated on a malware-scan status, and the generated project still has to compile, build and pass its generated tests before the run is accepted.Shahid, published 2026-08-20

Last released January 2024 at 0.0.6. The repository the package declares has been deleted — verified against the GitHub API, not just a failed fetch. The package is still on npm, so it installs; the source it was published from is no longer readable, which is a harder thing to discover than a stale version number.
🔴 Your Agent Wants to Call SAP. Now What?🔴 Your Agent Wants to Call SAP. Now What?Devtoberfest 2026 session INT-23, on what belongs between an agent and an SAP system. A solution advisor and an enterprise architect point Joule Desktop extensions at MCP servers built on API Management inside SAP Integration Suite, and ask it for business partners, orders and line items from an S/4HANA demo system; asked for the ten largest customers it answers from a sample of 200 orders rather than reading the whole table. They then open the API proxy behind it, where a spike arrest policy caps the backend at ten calls per second and the MCP server is configured to expose only the GET resources of the business-partner API so that an agent cannot create one, which is where the edges to Serve your application over MCP and Rate limiting hold. For totals across all sales orders they send the agent to SAP Business Data Cloud instead of the transactional system, since it aggregates and is read-only, and back through Integration Suite for writes such as journal entries.SAP Developers, published 2026-09-30
API Composition: Seamless Enterprise Data Access for Developers and AI AgentsAPI Composition: Seamless Enterprise Data Access for Developers and AI AgentsAPI Composition (formerly Graph, a capability of API Management) curates business data graphs from existing SAP and non-SAP API providers, so a query can navigate and expand relationships across systems through one composed API rather than hand-written integration code. Palak walks through combining SAP S/4HANA warehouse-stock data with Everstream Analytics risk data into one API, then exposing that composed API as an MCP server so an AI agent calls it with the same semantic context — the scenario behind API Management's MCP servers coverage.published 2026-07-27
Edge Integration Cell : Design, deploy and manage APIsEdge Integration Cell : Design, deploy and manage APIsWalks through creating an API artifact in API Management on the customer-managed Edge Integration Cell runtime, including the option to generate the artifact by importing an OpenAPI specification rather than from a URL or by hand. It then attaches an Authentication policy and a Quota step capped at four calls per minute, deploys, and shows both the resulting 401 and the quota-breach error in the Monitor logs. The author frames it as the first of a series on Edge Integration Cell's policies.published 2023-11-15
Graph on Integration Suite: Simplifying Multi-API Data Retrieval with Unified Business Data GraphGraph on Integration Suite: Simplifying Multi-API Data Retrieval with Unified Business Data GraphA hands-on walkthrough of Graph, the API Management feature of SAP Integration Suite also called Business Data Graphs, which exposes several OData APIs as one connected data model behind a single OData V4 or GraphQL endpoint. It covers enabling the capability and its Graph.KeyUser and GraphNavigator.Viewer role collections, creating BTP destinations and a service key for an S/4HANA system, then building a Business Data Graph over the Sales Order and Business Partner APIs so a mirrored SoldToParty association returns both in one call, in place of the two OData requests a Cloud Integration Content Enricher would otherwise merge.published 2026-01-09
Information Map – Introduction Series: Graph in SAP Integration SuiteInformation Map – Introduction Series: Graph in SAP Integration SuiteIntroduces Graph, an enhancement to API Management within SAP Integration Suite that gives developers a single API onto an organisation's business systems, modelled as one semantically connected business data graph, later renamed API Composition. Splits the work between an administrator, who enables SAP BTP destinations to the backend systems and builds the business data graph, and a developer, who explores it in the Graph Navigator tool and builds an application against the resulting Graph API.published 2024-02-21
MCP Gateway in Practice: Architecture, configuration, and hands-onMCP Gateway in Practice: Architecture, configuration, and hands-onA Devtoberfest 2026 integration-track session (INT-21) on the MCP gateway of SAP Integration Suite: curated enterprise APIs served to agents as MCP tools over JSON-RPC, behind the authentication, authorization and traffic policies an API artifact already carries, with the existing API layer left in place. The hands-on half composes S/4HANA plant, material-stock and supplier data with a non-SAP location-risk source into one business data graph, downloads its OpenAPI specification, creates an MCP server artifact with tools, prompts and a surge-protection policy over that endpoint, and publishes it as a product in Developer Hub of API Management, where an agent developer subscribes and gets OAuth credentials. An MCP client then asks for 15 brake pads and ranks plants by stock, location risk and distance from Walldorf, which is what the agent access to your systems edge rests on; the Q&A covers principal propagation to the backend, how errors reach the model, and which Integration Suite editions carry the gateway.SAP Developers
Modern integration at TÜV Rheinland: APIs, events and cloud transformationModern integration at TÜV Rheinland: APIs, events and cloud transformationTÜV Rheinland's migration from SAP Process Orchestration to SAP Integration Suite with API-led connectivity and event-driven architecture, told through business cases. The abstract names what was used: the SAP Integration Suite, Event Mesh capability, API Management, generative AI for faster development and SAP Cloud ALM for monitoring. It states nothing about how any of them was used, so the edges rest on the names and on the Platform migration the story starts from. A TechEd 2026 session (Wednesday 28 October, Berlin), written here from SAP's abstract; the recording is not yet published.
Powering Enterprise-Ready Agentic AI with SAP Integration SuitePowering Enterprise-Ready Agentic AI with SAP Integration SuiteA Devtoberfest 2026 session (INT-31) from SAP Integration Suite product management on the MCP gateway. The demo creates an MCP server in a design package from an API already deployed on the tenant, exposes two of its 300-odd resources as tools, attaches authentication and quota policies on a policies tab, and publishes the deployed endpoint as an AI product in Developer Hub of API Management, where an agent subscribes and receives a token, URL, key and secret; the calls then show up in monitoring, in message processing logs and in the analytics dashboard, which is the MCP exposure and the tool governance the edges rest on. Three AI features inside Cloud Integration follow: a content migration agent that converts a PI/PO Java mapping into a Groovy script and generates a second integration flow for its lookup, memory profiling during a flow simulation, and root-cause analysis on a failed message processing log.SAP Developers, published 2026-10-07

SAP PI Migration to BTP Integration Suite Patterns and learning experiencesSAP PI Migration to BTP Integration Suite Patterns and learning experiencesWalks through the integration patterns an SAP PI migration project moved onto SAP Cloud Integration iFlows — API Management proxies fronting calls into on-premise SAP systems over XI/SOAP via Cloud Connector, SFTP transfers, and eventing routes — and the operational lessons from running it: sizing JMS queues, choosing exactly-once JMS queues over Cloud Integration's Data Store for XI receiver adapters and at-least-once JMS for XI sender adapters, and workarounds for gaps in the migration tooling. The API Management proxies handle JWT validation against a non-SAP identity provider, IP filtering and OData-to-OpenAPI conversion in front of the iFlows.saikrishna_kalivarapu2, published 2024-12-04
