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

@wjsutton/tableau-powerpoint-tools

Companion MCP server for Tableau → PowerPoint workflows, designed to run alongside the official Tableau MCP server. It does not fork or wrap the official server — run both side by side and Claude (or any MCP client) sees one combined toolset.

Tools

  • resolve-view-url — turn a pasted Tableau view URL (Cloud or Server, any of the three URL shapes) into the LUIDs downstream calls need: view LUID, workbook LUID/name, isDashboard, plus any filter-<Field>=value params embedded in the URL. Replaces the list-views + get-workbook dance.
  • get-dashboard-structure — return a published view's complete structure: every sheet (with layout zone + normalised zoneFraction), fields with shelves/aggregations, sheet filters, upstream datasource LUIDs, a resolved chartTypeHint, and a pre-built, tiered fetchRecipe per sheet that you execute as-is against the official server's get-view-data or query-datasource. Workbook calculated fields are recursively inlined as VizQL ad-hoc calculations.
  • test-connection — sign in via REST and report { serverUrl, siteName, serverVersion, authenticatedUser }, or a classified, user-directed error (not configured, unreachable server, wrong site name, expired/revoked PAT). Call it first whenever any Tableau call fails with an auth error.

All tools make their own authenticated Tableau REST calls and follow the official server's AUTH contract — the same env vars configure both servers:

| AUTH | Variables | |-----------------|-----------| | pat (default) | PAT_NAME, PAT_VALUE | | direct-trust | JWT_SUB_CLAIM, CONNECTED_APP_CLIENT_ID, CONNECTED_APP_SECRET_ID, CONNECTED_APP_SECRET_VALUE (+ optional JWT_ADDITIONAL_PAYLOAD) | | uat | UAT_TENANT_ID, UAT_ISSUER, UAT_PRIVATE_KEY or UAT_PRIVATE_KEY_PATH (+ optional UAT_KEY_ID, UAT_USERNAME_CLAIM_NAME/UAT_USERNAME_CLAIM) |

Always required: SERVER (Tableau Cloud/Server URL); SITE_NAME may be empty (the Default site). Each of SERVER/SITE_NAME/PAT_NAME/PAT_VALUE also falls back to TABLEAU_* and then CLAUDE_PLUGIN_OPTION_TABLEAU_* variants — so the Claude plugin's configuration dialog, a legacy TABLEAU_* env setup, or an explicit MCP-config env block all work. Common server-URL mistakes (trailing slash, a pasted full view URL) are normalized before failing, and PAT_VALUE is redacted from every error and log line. JWTs are signed with node:crypto (HS256 / RS256) using only the scopes this server needs: tableau:content:read, tableau:workbooks:download. TABLEAU_POWERPOINT_AUTH overrides AUTH for this server only (useful when the official server runs hosted/OAuth). AUTH=oauth/passthrough are HTTP-deployment methods of the official server and are rejected here with guidance.

PowerPoint generation itself lives in the plugin's skill (python-pptx / PptxGenJS scripts) — see the tableau-to-powerpoint plugin.
