A small FastMCP-based Microservice that renders LaTeX to PDF. The server exposes MCP tools to render raw LaTeX or templates and produces artifacts (a .tex file and .pdf) under src/artifacts/. This repository is prepared to run locally and to be loaded by Claude Desktop (via the Model Context Protocol). The default entrypoint is runserver.py. - Render raw LaTeX to .tex and (optionally) .pdf using p

When the user wants to create or optimize in-app paywalls, upgrade screens, upsell modals, or feature gates. Also use when the user mentions "paywall," "upgrade screen," "upgrade modal," "upsell," "feature gate," "convert free to paid," "freemium conversion," "trial expiration screen," "limit reached screen," "plan upgrade prompt," or "in-app pricing." Distinct from public pricing pages (see page-cro) — this skill focuses on in-product upgrade moments where the user has already experienced value
An MCP server that triangulates customer support tickets and feature requests to help PMs decide what to build next. - Signal triangulation — Not just data access. Matches support tickets against feature requests to find convergent themes, then scores them with a weighted formula that gives convergent signals a 2x priority boost. - Composability — Designed to work with other MCP servers. Pass chur
KoliBri stands for "component library for accessibility" and was released as open source by the Informationstechnikzentrum Bund (ITZBund) for reuse and continued development. Together we make HTML accessible using reusable web components to ensure usability and accessibility. The HTML web standard is itself very “openly” specified in order to be as long-lasting and robust as possible. It therefore
