About abap2UI5

abap2UI5 is an MCP server published by the GitHub account abap2UI5. abap2UI5 dev loop for AI agents: validate views, screenshot, deploy and run apps - no SAP system

It runs on your own machine: your AI client starts it from the npm package @abap2ui5/mcp-server at version 1.0.0.

It asks for 2 secrets: A2UI5_MCP_SYSTEM_PASSWORD and GITHUB_TOKEN. Give it a key with the least access that still works.

Version 1.0.0 was published on 14 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 6 pass, 1 warn, 0 fail, 2 info. How we check.

A2UI5_MCP_UI5_CACHE_MBNoNoHow 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_LINT_WORKERNoNoSet 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_SYSTEM_INSECURE_TLSNoNoSystem mode: set to 1 to accept a certificate that cannot be verified. NODE_EXTRA_CA_CERTS with the CA is the better fix.
