GeneratorsCAPABAPUI5GeneratorsGetting from nothing to a project that runs, and from a project that runs to one that has the piece you just decided you need. Two different moments: the first is a one-time decision about layout, the second recurs for the life of the project.LLM integrationCAPUI5BTPABAPLLM integrationCalling a language model from application code with the tenant, destination and credential handling already solved instead using an SDK call with a hand-rolled key.OpenAPICAPABAPBTPOpenAPIHanding a description of the service to clients and tools — an API portal, a code generator, a partner who wants a contract before they write anything.TestingCAPBTPTestingProving the service still does what it did — against the model and the handlers, without a deployed system and without a database somebody has to keep clean.

Agent access to your codeCAPABAPUI5BTPAgent access to your codeLetting a coding agent read the project or the system you actually have, reach its model, its objects and its checks, and act on it. In file-based environments that works out of the box; complex systems need dedicated access capabilities. Whatever the environment, the agent also needs project- and framework-specific context, so it understands the thing in front of it rather than guessing from what it remembers of its training data. The transport is incidental: an MCP server, a language server or a CLI answer the same question, and what differs between them is how much of the real thing the agent can see. Distinct from [MCP servers](capability:mcp-servers), which is a protocol adapter on your own running service, and from [agent guidance](capability:agent-guidance), which is knowledge handed over as files rather than read from the thing itself.Agent guidanceCAPUI5BTPABAPAgent guidancePackaged knowledge you hand a coding agent so it gets a framework right unprompted — skills, rule files, instruction packs. Distinct from agent tooling, which is about building agentic features into your application, and from [agent access to your code](capability:agent-code-access), where the agent reads the real project instead of being handed a file about it.AuthenticationCAPBTPABAPUI5AuthenticationEstablishing who is calling: validating credentials or tokens, resolving the user, and making that identity available to the application. [Authorization](capability:authorization) decides what that identity may do; [identity provisioning](capability:identity-provisioning) manages its lifecycle across systems.DocumentationCAPUI5BTPABAPDocumentationFinding the answer in what has already been written, and writing it where it has not — first-party documentation made searchable by something other than a person scrolling it, including by an agent, and a document of custom code produced from the code itself.Serve your application over MCPCAPBTPABAPServe your application over MCPExposing selected application data and business operations to an AI agent through the Model Context Protocol. An application may also integrate remote services through [service integration](capability:service-integration), connecting its exposed contract with [agent access to your systems](capability:agent-systems-access). Development assistance belongs to [agent access to your code](capability:agent-code-access).Source controlABAPSource controlKeeping source code and development objects in version control, comparing their revisions, and moving them between development environments. Managed delivery of changes belongs to [transport management](capability:change-promotion).

@geertjanklaps/cds-toon-ai-protocol-adapter@geertjanklaps/cds-toon-ai-protocol-adapterA protocol adapter that serves CAP data as TOON — Token-Oriented Object Notation — instead of JSON, so a payload bound for a language model costs fewer tokens to send.independent, cap

@arc-mcp/xsuaa-auth@arc-mcp/xsuaa-authThe client-to-server authentication stack for an MCP server on SAP BTP: an XSUAA OAuth proxy, dynamic client registration, a chained bearer verifier, and a separate entrypoint for per-user principal propagation.independent, btp
It stops at the `AuthInfo` and the raw bearer token, and the README lists what stays with the consuming server: rate limiting, the scope and tool policy, the MCP transport, the SAP HTTP client's headers, and helmet-style hardening. The one piece of hardening it constrains rather than defers is the cross-origin opener policy, which it deliberately leaves unset because popup-based OAuth breaks under it. It is ESM-only on Node 22 or later and shares the host's Express and MCP SDK instances as peer dependencies, so a server on Express 4 cannot take it.

@gavdi/cap-mcp@gavdi/cap-mcpGenerates an MCP server from the CDS model — annotated entities become resources and annotated actions become tools, so an agent reaches the service without a second server being written.independent, cap

generator-easy-ui5generator-easy-ui5A Yeoman meta-generator that scaffolds UI5 projects, prompting for a target platform, and loads further sub-generators from the UI5 Community for TypeScript apps, launchpad plugins and libraries.community org, ui5

mcp-sap-docsmcp-sap-docsAn MCP server over seventeen cloned SAP documentation repositories — ABAP keyword docs, capire, OpenUI5, Cloud SDK, BTP — searched with BM25 and prebuilt embeddings fused by reciprocal rank fusion.independent, cap
It reads documentation, never a system: nothing in it opens a package.json, a CDS model or an ABAP client, so a question about what your own project does has to be answered elsewhere. The offline half is only as fresh as the submodules the last build pinned, and the index answers where something is written down rather than which of two packages fits a task.

secondsky/sap-skillssecondsky/sap-skillsForty SAP development plugins installed through the skills command line or the Claude Code and Codex marketplaces, with a record per plugin of what its claims were checked against.independent, btp
GPL-3.0, which is a licence to read before vendoring any of it into something you ship. Forty plugins is also a lot of always-available surface — the ledger is there because breadth and verification pull in opposite directions, and it does not resolve that so much as report it.

cds-toon-ai-protocol-adapter: a pragmatic way to cut AI token costs using SAP CAPcds-toon-ai-protocol-adapter: a pragmatic way to cut AI token costs using SAP CAPNames a cost most CAP-plus-LLM writing ignores: every JSON payload streamed to a model is billed by its verbosity, in latency as well as money. The plugin brings TOON — Token-Oriented Object Notation — to a CAP service so the wire format changes without the service code doing so, in a REST variant and an OData one, with token counts reported on both sides.published 2026-01-25
cds-launchpad-plugin supercharged & ready for the future - CAP Plugin, UI5 Tooling support & Async Launchpadcds-launchpad-plugin supercharged & ready for the future - CAP Plugin, UI5 Tooling support & Async LaunchpadThe maintainer on a set of changes rather than on the plugin's original purpose, which is indexing every SAPUI5 project in a workspace into one sandbox launchpad so all of them can be tested together. What moved: it became a CAP plugin, gained UI5 Tooling support, and moved to the async launchpad — each framed as keeping pace with where SAPUI5 itself is going rather than as a feature.published 2023-12-11
A Fiori Launchpad Sandbox for all your CAP-based projects - OverviewA Fiori Launchpad Sandbox for all your CAP-based projects - OverviewWhere cds-launchpad-plugin came from, told as a learning exercise: the author wanted a real problem to teach himself TypeScript on, and picked the thing he kept redoing in every CAP project — a launchpad to see all the UI applications in one place. The origin post for an entry whose 2023 update is also indexed here.published 2022-03-14
