Feed SAP Help, UI5 APIs & SAP Community Content into your AI with this Open Source MCP Server

[[{“value”:”

In this post I’m sharing my SAP Documentation MCP Server, a fast, lightweight way to give LLMs grounded access to official SAP docs, API references, real sample code, the SAP Community, and SAP Help. Less hunting through tabs, more precise answers right inside your AI tool.

What is MCP and why does it matter?

The Model Context Protocol (MCP) is a standard that lets AI assistants securely call tools and read external data. A strong MCP server brings generic models (like OpenAI) much closer to what many expect from Joule for Developers: up-to-date, context-specific answers backed by verifiable sources. MCP is getting adopted broadly, you can connect to servers from tools like Claude, VS Code, Cursor, and others.

Why this matters day-to-day: instead of a model relying on stale training data, it can fetch exactly the right page, API, or example at answer time. That reduces guesswork and aligns responses to the current SAP docs.

The challenge: SAP knowledge is scattered

SAP information lives across multiple places: the SAPUI5 developer guide, CAP guides, OpenUI5 APIs, Demokit samples, SAP Help, and the SAP Community. Even experienced developers spend time cross-checking sources; generic LLMs struggle even more, especially with UI5 API specifics (events, bindings, lifecycle), CAP annotations, or testing details. The result is friction, confusion, and answers that need manual verification.

This server unifies the important sources behind a single, predictable interface and uses fast, keyword-intent search so you get relevant matches quickly.

What this MCP server provides

Here is the GitHub Repository: https://github.com/marianfoo/mcp-sap-docs 

Coverage includes major SAP developer sources with a single search surface and consistent formatting:

• Documentation → SAPUI5, CAP, UI5 Tooling, wdi5, UI5 Web Components, Cloud MTA Build Tool, SAP Cloud SDK (JS/Java), SAP Cloud SDK AI

• OpenUI5 API & Samples → control APIs plus real Demokit sample projects

• SAP Community → search and return full content for the most relevant results

• SAP Help → search and retrieve complete pages with metadata

• Fast search → BM25 / SQLite FTS5 with context-aware boosts and metadata-driven routing

Under the hood, the server normalizes results (title, snippet, source, URL) so your client sees a consistent format across all sources, easy to scan and follow.

Use the hosted server (recommended)

No setup, just connect:

• STDIO (SSE): https://mcp-sap-docs.marianzeis.de/sse

• Streamable HTTP: https://mcp-sap-docs.marianzeis.de/mcp

Quick check:

# Public status
curl -sS https://mcp-sap-docs.marianzeis.de/status | jq .

# SSE handshake (should include “event: endpoint”)
curl -i -H ‘Accept: text/event-stream’ https://mcp-sap-docs.marianzeis.de/sse | head

Run it locally

Clone the repository and build locally:

git clone https://github.com/marianfoo/mcp-sap-docs
cd mcp-sap-docs
npm ci
./setup.sh
npm run build

# Start STDIO server
node dist/src/server.js

# Or start Streamable HTTP (modern protocol)
npm run start:streamable

Local health checks:

# HTTP status
curl -sS http://127.0.0.1:3001/status | jq .

# SSE proxy
curl -sS http://127.0.0.1:18080/status | jq .

# Streamable HTTP
curl -sS http://127.0.0.1:3122/health | jq .

Integrate with your client

Cursor

Add a remote MCP server via ~/.cursor/mcp.json. See Cursor docs: docs.cursor.com

{
“mcpServers”: {
“sap-docs-remote”: {
“url”: “https://mcp-sap-docs.marianzeis.de/sse”
}
}
}

VS Code (GitHub Copilot Chat)

Workspace-level config: VS Code MCP servers

{
“servers”: {
“sap-docs”: {
“type”: “http”,
“url”: “https://mcp-sap-docs.marianzeis.de/mcp”
}
}
}

Deep dive: how features work

Docs (including search)

The server uses SQLite FTS5 with the BM25 ranking function, simple, fast, and reliable without external dependencies. For developer queries it often beats generic vector search because the keyword intent is clear (control names, APIs, annotations). Queries are expanded with synonyms and acronyms (for example, UI5 ↔ SAPUI5), and results are boosted depending on the detected context (UI5, CAP, testing). All sources are defined in one central metadata.json, so adding a source does not require code changes.

Community

Community search follows the site’s “Best Match” behavior and returns full content for the most relevant posts. That gives you the context and code right away, which is especially useful for tricky issues where official docs are thin. Explore more at SAP Community.

SAP Help

The Help integration is a two-step flow: first search, then fetch the complete page with metadata. This offers broad coverage across S/4HANA, BTP, Analytics Cloud, Fiori, ABAP, and more. Note: it relies on private endpoints of the SAP Help Portal and may change. Browse help.sap.com.

Technical snapshot

• Three modes → STDIO MCP, HTTP status, Streamable HTTP MCP

• BM25-only → no external vector services; fast and robust

• Metadata-first → add new sources via metadata.json without code changes

Production is managed with process supervision and CI/CD; documentation sources are updated on a regular cadence so you get fresh content without manual steps.

Real-world workflows

• “How do I implement a SAPUI5 wizard with validation?” → official guide, API links, and sample patterns

• “How do I test table interactions with wdi5?” → testing docs and relevant community posts

• “How do I configure S/4HANA Fiori Launchpad?” → SAP Help pages with step-by-step instructions

Here’s how it looks in Claude after adding the connector:

Once connected, you can open the tools view, pick the server, and run a docs search. The top results render with titles, short snippets, and direct links:

Source map: repositories and paths

Add new sources (generic)

This server is metadata-driven. To add a new source:

• Add an entry in src/metadata.json with id, libraryId, sourcePath, baseUrl, pathPattern, and anchorStyle.

• Run npm run build to rebuild the index and FTS database.

{
“id”: “my-source”,
“type”: “documentation”,
“libraryId”: “/my-source”,
“sourcePath”: “my-source/docs”,
“baseUrl”: “https://example.com”,
“pathPattern”: “/{file}”,
“anchorStyle”: “github”
}

You don’t need code changes, just metadata and a rebuild.

Sources (open)

• SAPUI5 documentation

• OpenUI5 API and source code of controls

• OpenUI5 samples (Demokit)

• CAP, wdi5, UI5 Tooling, Cloud MTA Build Tool

• SAP Cloud SDK (JS/Java) and SAP Cloud SDK AI

SAP’s MCP momentum

SAP itself is investing in MCP servers. A good example is the CAP MCP server: https://github.com/cap-js/mcp-server

How to contribute

If you know a document exists in one of the sources but the LLM can’t find it, please share (1) your question, (2) the MCP tool call, and (3) the link to the expected document. This lets me reproduce and improve the search. Use the issue template:

Open issue with the “Missing Documentation Search Result” template

Want to propose adding a new source? Use this template:

Open issue with the “New Documentation Source” template

Notes

• Hosted is the easiest. Local is great when you need offline behavior.

• SAP Help relies on private APIs and may change.

• Feedback is welcome: the more specific (query, tool log, expected link), the faster I can tune relevance.

Thanks for reading, try the hosted endpoints, or clone and run it locally. If something isn’t found, file an issue with the template above and I’ll take a look.
