MCP server for SAPUI5/OpenUI5 development
Using io.github.UI5/mcp-server in Claude, Cursor, Gemini CLI, Cline, or Zed?
MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).
Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

mcpindex.integrity.descriptionpassINFOevidence“No malicious instructions found”via static_description
- - Semantic screen only - the deterministic conformance probe has not run on this server
- - Confidence is reported but not yet calibrated (v1)
- - Screen reads the tool description, not the live behavior
- - advisory
- - registry description only no input schema
- - screen model 8b
Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-07-31).
Contracts can change after screening, with no version bump. The gate pins io.github.UI5/mcp-server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Set to an empty string to allow any domains. For wildcard subdomains, prefix the domain with a dot: '.example.com'. This will match 'www.example.com' but not 'example.com'.
UI5_MCP_SERVER_RESPONSE_NO_STRUCTURED_CONTENTSet to any value to disable structured content in the MCP server responses.
UI5_MCP_SERVER_RESPONSE_NO_RESOURCESSet to any value to disable resources in the MCP server responses, see https://modelcontextprotocol.io/specification/2025-06-18/server/resource. This is useful for clients that do not support resources, see https://modelcontextprotocol.io/clients, such as Cursor or the Gemini CLI.
UI5_LOG_LVLInternal log level (https://ui5.github.io/cli/stable/pages/Troubleshooting/#changing-the-log-level): 'silent', 'error', 'warn', 'info', 'perf', 'verbose' or 'silly'
UI5_DATA_DIRDirectory where the MCP server stores its data, such as cached API references. Defaults to the '.ui5' directory in the user's home directory.
Local-first MCP gateway and homelab control plane with CLI, HTTP API, and web UI.
Rust MCP and CLI server for Sonarr, Radarr, Prowlarr, Plex, Jellyfin, and download clients.
