alpic-ai/skybridge is a full-stack TypeScript and React framework for building MCP apps, which are interactive user interfaces connected to MCP servers and usable in clients such as Claude and ChatGPT. It helps developers create type-safe apps with development tooling, client compatibility, React hooks, and agent-oriented APIs. The catalogue skills, instructions, setting, and hook support workflows for building MCP apps with Skybridge.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00746 | $0.00746 |
| Opus 5 | $0.00373 | $0.00373 |
| Sonnet 5 | $0.00149 | $0.00149 |
| Haiku 4.5 | $0.00075 | $0.00075 |
Grade A, and why
skybridge AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What is Skybridge
Skybridge is a fullstack TypeScript framework for building ChatGPT Apps and MCP Apps — interactive React views that render inside AI conversations.
The core loop: an MCP server exposes tools. When the host (ChatGPT, Claude, VSCode…) calls a tool, the server returns structured data and a reference to a React view. The host renders that view in an iframe. The view can read tool output, call other tools, send follow-up messages, and sync UI state back to the model.
Skybridge wraps two host runtimes behind one API:
- Apps SDK — ChatGPT's proprietary
window.openairuntime - MCP Apps — the open
ext-appsspec (JSON-RPC postMessage)
Developers write one server (backend) and view(s) (frontend). Skybridge detects the runtime at load time.

Development
Prerequisites: Node.js >= 24.14.0, pnpm 10+ (corepack enable).
pnpm install # setup
Validation

pnpm --filter skybridge test:unit
pnpm --filter skybridge test:format
pnpm --filter skybridge build
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skybridge AGENTS.md is an instructions file published in the GitHub repository alpic-ai/skybridge (1,991 stars, last pushed 4d ago), licensed MIT. It adds 746 tokens to every session, about $0.0037 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
