Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.
Convert an informal mathematical idea into a precise theorem, lemma, or proof scaffold with explicit assumptions, dependency structure, and clearly marked gaps. Use when developing a new proof, formalizing intuition, planning a theorem structure, or evaluating whether an argument is actually complete.
Tool lifecycle UI components for React/Next.js from ui.inference.sh. Display tool calls: pending, progress, approval required, results. Capabilities: tool status, progress indicators, approval flows, results display. Use for: showing agent tool calls, human-in-the-loop approvals, tool output. Triggers: tool ui, tool calls, tool status, tool approval, tool results, agent tools, mcp tools ui, function calling ui, tool lifecycle, tool pending
Generate a traceability report that cross-references the acceptance criteria of an artefact — a user story (US-XXX), a maintenance task (WI-XXX), an already implemented feature (FT-XXX), or any document whose criteria have a coded identifier (AC-001, 1.1, R-3…) — against the repository's test cases and test artefacts. For each criterion, state what covers it, its status (Covered / Partial / Not covered), whether the test ran and with what result, and close with a coverage verdict. It does not run the suite: it delegates execution to quality-check. Always activate when the user asks to validate coverage, generate a traceability matrix or report, verify that acceptance criteria are tested, check whether a piece of work or a feature is covered by tests, or mentions "traceability", "coverage matrix" or "validate acceptance criteria", even if they do not name the exact format.
Transform a user-uploaded photograph into one horizontal collectible memory card with a large quiet editorial illustration, six integrated journaling-sticker motifs, three small English keywords beneath the left illustration, tactile paper grain, and deliberately clumsy flat color fields. Use when Codex needs to P图, edit, redraw, stylize, or turn a travel, street, landscape, lifestyle, portrait, or pet photo into a minimalist postcard-like card or sticker-card in this visual language. Preserve recognition through one same-medium identification anchor and optionally one exact place-defining landmark text shown once; never retain an unintended photorealistic patch, signature, or watermark.

Triage a UI Verify build from your coding agent via the UI Verify MCP: classify changed stories as real regressions, cosmetic reflows, or rendering noise; summarize real regressions for a PR comment; and accept baselines in bulk. Use after a UI Verify build reports changes when you want the agent to review, summarize, or accept them from the terminal instead of clicking through the dashboard. Triggers: “triage this build,” “summarize the visual regressions,” “accept all the new baselines.”

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
