# ABAP Model Context Protocol Server SDK [Discord](https://discord.gg/jf2FhnFvSn) - for all ABAP-AI repos. ## Overview ABAP implementation of the [Model Context Protocol](https://modelcontextprotocol.io/introduction), supporting up to version [2025-11-25](https://modelcontextprotocol.io/specification/2025-11-25). \ **Note** that this is only a server implementation as I currently see no realistic way to support SSE streaming which is mandatory for the client. Supported protocol versions: 2025-03-26, 2025-06-18, 2025-11-25 Note that old protocol versions might be dropped after a while especially if they increase maintenance effort. ## Documentation See [Overview](docs/Overview.md) in docs folder. ## Used ABAP OpenSource projects Special thanks to: - [ajson](https://github.com/sbcgua/ajson) integrated as zmcp_ajson - [abaplint](https://github.com/abaplint/abaplint) for review and more important 7.02 downport - [abapGit](https://github.com/abapGit/abapGit) for source code control Find more awesome projects at [dotabap](https://dotabap.org/). ## Features & Limitations Currently implemented: - Prompts - Resources - Tools (incl. optional output schemas and task-augmented execution) - Tasks - long-running background work with client polling - Completions - autocomplete for prompt and resource-template arguments - DDIC-based schema generation plus a JSON schema builder and validator No SSE support --> no notifications and therefore no support of listChanged, subscribe and logging.\ Not implemented: - Sampling - considered for the future, open an issue if you have a use case that would benefit from it - Elicitation - without SSE I see no proper way to implement this - Roots - likely irrelevant for ABAP - Further notifications not relevant without SSE: Cancellation, Progress, Logging ## Authorization Implement the standard [Authorization](https://modelcontextprotocol.io/specification/2025-06-18/basic/authorization) in ABAP via custom code is not feasible, we have to rely on ABAP features. \ An overview of likely options is outlined in [Authentication Documentation](./docs/Authentication.md). ## Authentication OAuth is suggested but outside of newer S/4HANA releases challenging, for options see [Authentication](./docs/Authentication.md). Further suggestions are welcome. ## Roadmap See currently open issues for the next planned steps. Longer term I intend to add features to create modular MCP servers based on reusable implementations. ## FAQ See [FAQ](./docs/FAQ.md). ## Contributing Feel free to: - Open issues for bug reports - Use [Discord](https://discord.gg/jf2FhnFvSn) for discussions - Suggest improvements - Pull requests are welcome but ensure they are tested and follow the overall style, if in doubt open an issue first ## GenAI Notice Part of the coding was generated using AI, mostly with Sonnet 3.7/4 and GitHub Copilot. Detailed documentation is largely AI generated - only high-level reviewed.
