Zoom Plugin is a Claude plugin that helps plan, build, and debug Zoom integrations across APIs, SDKs, webhooks, bots, and MCP connections. It is for developers creating Zoom applications, with catalogue entries providing guidance, workflows, and MCP connectors for selecting and implementing the relevant Zoom products.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 5.1 | $0.00044 | $0.01991 |
| Opus 5.5 | $0.00018 | $0.00796 |
| Sonnet 5.5 | $0.00009 | $0.00398 |
| Haiku 4.5 | $0.00004 | $0.00199 |
Grade A, and why
setup-zoom-websockets scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 261 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/setup-zoom-websockets
Background reference for persistent Zoom event streams. Prefer workflow routing first, then use this file when WebSockets are plausibly better than webhooks.
WebSockets vs Webhooks
| Aspect | WebSockets | Webhooks |
|---|---|---|
| Connection | Persistent, bidirectional | One-time HTTP POST |
| Latency | Lower (no HTTP overhead) | Higher (new connection per event) |
| Security | Direct connection, no exposed endpoint | Requires endpoint validation, IP whitelisting |
| Model | Pull (you connect to Zoom) | Push (Zoom connects to you) |
| State | Stateful (maintains connection) | Stateless (each event independent) |
| Setup | More complex (access token, connection) | Simpler (just endpoint URL) |
Choose WebSockets when:
- Real-time, low-latency updates are critical
- Security is paramount (banking, healthcare, finance)
- You don't want to expose a public endpoint
- You need bidirectional communication
Choose Webhooks when:
- Simpler setup is preferred
- Small number of event notifications
- Existing HTTP infrastructure
Prerequisites
- Server-to-Server OAuth app or admin-managed General App in Zoom Marketplace
- Client ID and Client Secret; S2S also requires the Account ID
- WebSocket subscription with events enabled
Need to create/configure the app first? Use Marketplace app management for app creation, manifest validation, app-owned WebSocket/event subscription scopes, and the
WEB_SOCKETsubscription enum before connecting. Start from the General admin or S2S WebSocket base, then select the WebSocket delivery method under Features > Access.
Need help with S2S OAuth? See the zoom-oauth skill for complete authentication flows.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

setup-zoom-websockets is a skill published in the GitHub repository zoom/zoom-plugin (7 stars, last pushed 21d ago), licensed MIT. It adds 44 tokens to every session and 1,991 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 92% identical to zoom-websockets, differing in 11 lines, and is treated as a copy.
