Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@lisa-mcp/arc1-extension

npm

LISA's SAP object-translation tools, packaged as an ARC-1 extension — loaded in-process by an ARC-1 instance so they reuse its authenticated SAP client, safety ceiling, scope policy, audit trail, and per-user principal propagation. No second auth stack, no second deployment.

Three tools are exposed: Custom_TranslateListLanguages, Custom_TranslateGetTexts, Custom_TranslateSetTexts — the same wire contract as the standalone LISA MCP server, sharing @lisa-mcp/core.

Install

npm install @lisa-mcp/arc1-extension

The published artifact is a single self-contained ESM bundle at dist/index.js (@lisa-mcp/core is inlined). arc-1 and zod are peer dependencies: they are provided by the host ARC-1 process at runtime — zod in particular MUST resolve to ARC-1's own instance, since its registry runs z.toJSONSchema() on the tool schemas and plugin + registry have to share one zod.

Prefer building from source (development, or pinning to a commit)? Clone the LISA repo and run npm ci && npm run build --workspace packages/arc1-extension — same bundle, at packages/arc1-extension/dist/index.js.

Use

ARC-1 loads code plugins from ARC1_PLUGINS — a CSV of absolute paths to each plugin's entry file. Point it at the installed bundle:

ARC1_PLUGINS=/abs/path/to/node_modules/@lisa-mcp/arc1-extension/dist/index.js
SAP_ALLOW_WRITES=true
SAP_ALLOW_PLUGIN_RAW_WRITES=true        # all three tools POST → require the raw-write opt-in
SAP_I18N_SERVICE_PATH=/sap/bc/http/sap/zi18n_service   # optional override

The plugin registers under the runtime name lisa-arc1-extension (its ARC-1 identity, kept stable across the npm rename). Requires LISA's ZCL_I18N_SERVICE handler class installed on the target SAP system (three per-platform variants — see the LISA repo's abap/ folder).

Full runbook — Docker image, Cloud Foundry, the write-flag rationale — in docs: ARC-1 extension deployment.

Versioning

Released on its own cadence, independent of the LISA product version. Git tag arc1-extension-vX.Y.Z; see docs: Releasing.
