How abap2UI5 compares

Against every graded Developer tools MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 77/100; higher than 45% of 1,119 Developer tools servers
Tools: 30; the typical Developer tools server has 7
Tools that change things: 13%; typical: 5%. Fewer write tools means less an agent can break
GitHub stars: 1; more than 50% of 855 Developer tools servers
Downloads a week: 28; more than 11% of 436 Developer tools servers with a package

What the publisher says

From the abap2UI5 repository's README, as published. We do not edit it. Read it on GitHub

mcp-server

The MCP server for abap2UI5 — gives any AI coding agent (Claude Code, Cursor, VS Code Copilot, or any MCP client) the full abap2UI5 development loop, without an SAP system:

examples -> app_guide -> validate_view + screenshot_view -> deploy_app -> build_backend -> run_app -> pitfalls
(has somebody  (how an app  (SECONDS, no system:        (write ABAP,  (transpile      (boot headless,  (what a green
 built it       is built)    is the view legal,          lint)         to Node)        errors +         run still
 already?)                   and what does it LOOK like)                               SCREENSHOT)      does not prove)

The agent writes an ABAP class, validates the view and looks at a picture of it in seconds, deploys it, boots it in a real browser and looks at the running app — then iterates. Everything runs locally on infrastructure that already guards the abap2UI5 ecosystem in CI: the abaplint transpiler + open-abap runtime, the framework's express shim, the samples-controls build and boot gates, and the linter validation core.

Quick start

One-click install

Every button registers the same stdio server, named abap2ui5:

{"command":"npx","args":["--yes","-p","@abap2ui5/mcp-server","abap2ui5-mcp"]}

Claude Code plugin. The abap2UI5 plugin bundles the framework's agent skills (building an app, the ABAP and UI5 pitfall catalogues, the view-chain layout, ...) together with this server, registered the same way as above — one install for both:

/plugin marketplace add abap2UI5/abap2UI5
/plugin install abap2ui5@abap2ui5

abap2UI5: common questions

Is abap2UI5 MCP server safe?: Mostly: it is graded B (77/100). Read the abap2UI5 safety report
How do I install abap2UI5?: It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does abap2UI5 need an API key?: Yes. The registry entry asks for A2UI5_MCP_SYSTEM_PASSWORD, GITHUB_TOKEN.
Is abap2UI5 maintained?: The last commit was 21 days ago (2026-10-14). The latest release is v1.0.0.
What can I use instead of abap2UI5?: Servers from other publishers that do the same job: walkerOS Flow MCP server, Aiven MCP server and Ateam MCP server. Compare all abap2UI5 alternatives.
How does abap2UI5 compare with other Developer tools MCP servers?: safety score 77/100 (higher than 45% of 1,119 Developer tools servers); tools 30 (the typical Developer tools server has 7); tools that change things 13% (typical: 5%. Fewer write tools means less an agent can break). Full comparison.

Credentials it needs

AI_VIEW_CHECK_HOMECheckout or install of @abap2ui5/linter (validate_view, fix_view, screenshot_view). Default: the peer npm installs beside the server. A set value is authoritative.
A2UI5_HOMEabap2UI5 framework checkout (app_guide, api_reference, pitfalls; backend when present). Default: ../abap2UI5, else the GitHub mirror and the npm runtime.
SAMPLES_CONTROLS_HOMEsamples-controls checkout (capabilities, examples, generation_rules, scope_of, UI5 for screenshots). Default: ../samples-controls, else the GitHub mirror.
SAMPLES_HOMEabap2UI5/samples checkout, one of the catalogues examples searches. Default: ../samples, else the GitHub mirror.
SAMPLES_STACK_HOMEabap2UI5/samples-stack checkout (OData, RAP, APC, launchpad samples). Default: ../samples-stack, else the GitHub mirror.
APP_TEMPLATE_HOMEabap2UI5/app-template checkout that scaffold_app serves and add_agent_setup executes. Default: ../app-template, else the GitHub mirror.
DOCS_HOMEabap2UI5/docs checkout that docs_search reads. Default: ../docs, else the GitHub mirror.
ABAP_CLOUD_GUI_HOMEabap2UI5-addons/abap-cloud-gui checkout (with npm ci done) whose report2cloud converter migrate_report runs. Default: ../abap-cloud-gui; no mirror.
POPUPS_HOMEabap2UI5-addons/popups checkout whose popups migrate_report with deploy: true writes into the dev sandbox beside the converted class. Default: .deps/popups of the abap-cloud-gui checkout, ../popups beside it, then its build/popups.
OPENUI5_SRCOpenUI5 source checkout scope_of reads the JSDoc from (via samples-controls). Default: ../fork-openui5 next to samples-controls.
A2UI5_MCP_WORKSPACEWhere the npm backend installs, the dev sandbox lives and a framework clone lands. Default: ~/.abap2ui5-mcp.
A2UI5_MCP_BACKENDWhich backend runs the apps: npm (the @abap2ui5/node-runtime package, even beside a checkout) or clone (clone the framework). Default: decided per call.
A2UI5_MCP_RUNTIME_VERSIONPin the @abap2ui5/node-runtime release (X.Y.Z) the npm backend installs. Default: the registry's latest.
A2UI5_MCP_PORTPort of the local backend run_app boots against. Default: 3000.
A2UI5_MCP_UIWhether app_start/app_describe/app_act declare their MCP Apps screen (ui://abap2ui5/app-screen): auto (default - when the client advertises the io.modelcontextprotocol/ui extension), on, off.

A2UI5_MCP_UI5_CACHE_MBHow many MB of UI5 answers from the CDN (sdk.openui5.org) run_app and interact_app keep in memory across calls, so a second boot does not download them again. 0 switches the cache off. Default: 64.
A2UI5_MCP_RENDER_PAGESPages (Chromium tabs) of validate_view's warm render gate, which concurrent calls queue on. Default: 2 (1 to 8).
A2UI5_MCP_CHROMIUMChromium binary for run_app and interact_app. Default: CHROMIUM_BIN, Playwright's managed browser, then a system chromium.

A2UI5_MCP_PREBUILT_URLWhere build_backend mode prebuilt downloads the backend from. Default: the framework's release asset.
A2UI5_MCP_LINT_WORKERSet to 0 to run every lint as a fresh abaplint process. Default: a long-lived worker keeps @abaplint/core with the framework parsed and lints a deploy in milliseconds (the CLI runs whenever the worker cannot stand in for it).
A2UI5_MCP_LINT_IDLE_MSHow long the warm lint worker (about 300 MB with the framework parsed) is kept without a request before it exits, in milliseconds; the next lint starts a fresh one. 0 keeps it for the server's life. Default: 10 minutes.

A2UI5_MCP_SYSTEM_URLSwitches on the SYSTEM MODE: the app tools against this real SAP system instead of the sandbox loop. The launch URL, e.g. https://host:44300/sap/bc/z2ui5?app_start={class}&sap-client=100.
A2UI5_MCP_SYSTEM_USERSystem mode: the SAP user the app tools log on with (Basic authentication).
A2UI5_MCP_SYSTEM_PASSWORDsecretSystem mode: the password of A2UI5_MCP_SYSTEM_USER. Or A2UI5_MCP_SYSTEM_PASSWORD_CMD, to keep it out of the configuration.
A2UI5_MCP_SYSTEM_PASSWORD_CMDSystem mode: a shell command that prints the password (a keychain lookup) - instead of A2UI5_MCP_SYSTEM_PASSWORD.
A2UI5_MCP_SYSTEM_INSECURE_TLSSystem mode: set to 1 to accept a certificate that cannot be verified. NODE_EXTRA_CA_CERTS with the CA is the better fix.
GITHUB_TOKENsecretOptional token sent to api.github.com only, to raise the rate limit of the docs tree listing (GH_TOKEN is read too).
