Our reading of abap2UI5, from the data

abap2UI5 is a browser automation MCP server from abap2ui5, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

With 1 GitHub stars it ranks #452 of 1,199 browser automation servers we index.

It runs locally on your machine over stdio and needs 2 secrets (A2UI5_MCP_SYSTEM_PASSWORD, GITHUB_TOKEN); use a scoped, least-privilege key.

Install abap2UI5 MCP server

claude mcp add abap2ui5 -e A2UI5_MCP_SYSTEM_PASSWORD='<a2ui5-mcp-system-password>' -e GITHUB_TOKEN='<github-token>' -- npx -y @abap2ui5/mcp-server

Configuration

Variable	Required	Secret	Description
AI_VIEW_CHECK_HOME	—	—	Checkout 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_HOME	—	—	abap2UI5 framework checkout (app_guide, api_reference, pitfalls; backend when present). Default: ../abap2UI5, else the GitHub mirror and the npm runtime.
SAMPLES_CONTROLS_HOME	—	—	samples-controls checkout (capabilities, examples, generation_rules, scope_of, UI5 for screenshots). Default: ../samples-controls, else the GitHub mirror.
SAMPLES_HOME	—	—	abap2UI5/samples checkout, one of the catalogues examples searches. Default: ../samples, else the GitHub mirror.
SAMPLES_STACK_HOME	—	—	abap2UI5/samples-stack checkout (OData, RAP, APC, launchpad samples). Default: ../samples-stack, else the GitHub mirror.
APP_TEMPLATE_HOME	—	—	abap2UI5/app-template checkout that scaffold_app serves and add_agent_setup executes. Default: ../app-template, else the GitHub mirror.
DOCS_HOME	—	—	abap2UI5/docs checkout that docs_search reads. Default: ../docs, else the GitHub mirror.
ABAP_CLOUD_GUI_HOME	—	—	abap2UI5-addons/abap-cloud-gui checkout (with npm ci done) whose report2cloud converter migrate_report runs. Default: ../abap-cloud-gui; no mirror.
POPUPS_HOME	—	—	abap2UI5-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_SRC	—	—	OpenUI5 source checkout scope_of reads the JSDoc from (via samples-controls). Default: ../fork-openui5 next to samples-controls.
A2UI5_MCP_WORKSPACE	—	—	Where the npm backend installs, the dev sandbox lives and a framework clone lands. Default: ~/.abap2ui5-mcp.
A2UI5_MCP_BACKEND	—	—	Which 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_VERSION	—	—	Pin the @abap2ui5/node-runtime release (X.Y.Z) the npm backend installs. Default: the registry's latest.
A2UI5_MCP_PORT	—	—	Port of the local backend run_app boots against. Default: 3000.
A2UI5_MCP_UI	—	—	Whether 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_APP_FORMAT	—	—	The default answer format of the app tools: snapshot (default) or adaptive-card (the snapshot plus an Adaptive Card 1.5 as an embedded resource, for card-rendering hosts).
A2UI5_MCP_OFFLINE	—	—	Set to 1 for no network: no UI5 CDN fallback, no GitHub mirror, no registry lookup.
A2UI5_MCP_REMOTE	—	—	Set to 0 to switch off the read-only GitHub mirror used when no checkout is found.
A2UI5_MCP_REMOTE_DIR	—	—	Cache directory of the GitHub mirror. Default: <tmp>/abap2ui5-mcp-remote.
A2UI5_MCP_REMOTE_TTL_MS	—	—	How long a mirrored copy is used before it is refreshed, in milliseconds. Default: one day.
A2UI5_MCP_UI5_CACHE_MB	—	—	How 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_PAGES	—	—	Pages (Chromium tabs) of validate_view's warm render gate, which concurrent calls queue on. Default: 2 (1 to 8).
A2UI5_MCP_CHROMIUM	—	—	Chromium binary for run_app and interact_app. Default: CHROMIUM_BIN, Playwright's managed browser, then a system chromium.
A2UI5_MCP_SCREENSHOT_DIR	—	—	Where run_app and interact_app write their PNGs (the newest 50 are kept) and build_backend its log. Default: <tmp>/abap2ui5-mcp-screenshots.
A2UI5_MCP_PREBUILT_URL	—	—	Where build_backend mode prebuilt downloads the backend from. Default: the framework's release asset.
A2UI5_MCP_LINT_WORKER	—	—	Set 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_MS	—	—	How 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_LINT_TIMEOUT_MS	—	—	Hard timeout of the abaplint run, in milliseconds. Default: 5 minutes.
A2UI5_MCP_SCOPE_TIMEOUT_MS	—	—	Hard timeout of scope_of, in milliseconds. Default: 5 minutes.
A2UI5_MCP_BUILD_TIMEOUT_MS	—	—	Hard timeout of a build, the prebuilt download and the npm install, in milliseconds. Default: 30 minutes.
A2UI5_MCP_UNIT_TIMEOUT_MS	—	—	Hard timeout of the ABAP Unit runner, in milliseconds. Default: 10 minutes.
A2UI5_MCP_SYSTEM_URL	—	—	Switches 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_USER	—	—	System mode: the SAP user the app tools log on with (Basic authentication).
A2UI5_MCP_SYSTEM_PASSWORD	—	yes	System 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_CMD	—	—	System mode: a shell command that prints the password (a keychain lookup) - instead of A2UI5_MCP_SYSTEM_PASSWORD.
A2UI5_MCP_SYSTEM_INSECURE_TLS	—	—	System mode: set to 1 to accept a certificate that cannot be verified. NODE_EXTRA_CA_CERTS with the CA is the better fix.
GITHUB_TOKEN	—	yes	Optional token sent to api.github.com only, to raise the rate limit of the docs tree listing (GH_TOKEN is read too).
