Fify tools (2, 1 write)

write = sends, deletes, buys or posts
  • read_information_ui_runwrite actionFree

    App-only unseen-frame reader for the mounted Fify widget.

  • render_information_uiFree

    Render a fully grounded answer as a non-consequential interactive information view when structure or interaction materially improves it. Complete factual reasoning first and always pass the authoritative plain answer. If the user supplied sufficient facts, use them directly and invoke immediately without extra retrieval. For a named real-person profile, set profileSubject to the canonical name unless the user requests no image; Fify will perform a bounded trusted Wikimedia portrait lookup. Pre-resolved attributed Wikimedia or Openverse media may also be supplied, but never invent or guess media URLs.

Fify plugin marketplace

Fify turns grounded AI answers into trusted interactive comparisons, plans, checklists, timelines, and decision views. It preserves the complete plain-language answer as an authoritative fallback and performs no consequential actions.

This repository is a Git-backed marketplace for Codex. The plugin is self-contained: it requires Node.js 20 or newer, performs no separate npm or pnpm install, asks users for no Fify account or end-user API key, and runs a bundled deterministic information-view compiler locally.

Install in Codex

codex plugin marketplace add renfei-design/fify-plugin
codex plugin add fify@fify

Start a new Codex task after installation, then ask normally or tag @Fify:

  • Compare these options by cost and risk.
  • Make this rollout plan a checklist I can work through.
  • Show these milestones as a timeline.

The repository is the marketplace. No package installation, Fify account, or end-user API key is required.

Use with ChatGPT

This Git marketplace cannot be added directly as a user-defined ChatGPT marketplace. You can still use Fify in ChatGPT through a developer-mode MCP connection:

  1. Open Settings → Security and login and enable Developer mode.
  2. Open the ChatGPT Plugins page and select the plus button.
  3. Name the connection Fify and use the public MCP endpoint below.
  4. Review the discovered read-only tool, create the connection, and add it to a new chat.

https://fify-chatgpt.renfei1992.chatgpt.site/api/mcp

Developer mode availability depends on the user's account and workspace policy. Public discovery across ChatGPT and Codex requires publication to OpenAI's universal plugin directory. This repository is the Codex distribution source and the hosted endpoint is the direct ChatGPT connection source; neither makes Fify automatically discoverable in ChatGPT. See OpenAI's connection guide and plugin packaging guide.

Use from another MCP client

Fify also exposes a public Streamable HTTP MCP endpoint for compatible clients:

https://fify-chatgpt.renfei1992.chatgpt.site/api/mcp

The tool always returns a complete plain-language fallback. The inline interactive view requires a host that supports the MCP Apps UI extension.

See MARKETPLACE_LISTING.md for verified listing metadata, capabilities, limitations, and submission copy.

What is included

  • A Codex plugin manifest and Fify information-UI skill.
  • A bundled local MCP server with renderinformationui.
  • Product screenshots, activation evals, and reviewer cases.
  • Validation and end-to-end protocol smoke tests.
  • Official MCP Registry metadata for the public remote endpoint.

The local compiler does not research or verify facts. Codex supplies the grounded answer and sources, and Fify validates and renders that material. The bundled server limits each host identity to 20 successful renders per UTC day and two concurrent renders.
