## What it does

This skill teaches Codex how to configure Vercel Connect. It exchanges Vercel OIDC tokens for third-party credentials without storing static secrets. Three subject types exist. Choose `user` for end-user actions, `app` for bot calls, or `jwt-bearer` for assertion grants under RFC 7523.

Guidance covers both the CLI and the `@vercel/connect` package. Commands like `vercel connect create` set up connectors and open a browser window whenever OAuth consent is required.

Without running `vc env pull`, local SDK calls fail. Run terminal commands inside the folder containing `package.json` or pass `--cwd`, otherwise automated connection linking does not run.

## Requirements
- Works with: GitHub, Snowflake, Linear

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill vercel-connect -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/vercel-connect/SKILL.md` — For all projects use ~/.agents/skills/

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill vercel-connect -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/vercel-connect/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/vercel-connect/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/vercel-connect/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins vercel-connect
```

2. **Manually: put the files in place**
- File: `.github/skills/vercel-connect/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/vercel/skills/vercel-connect
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/vercel-connect/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/vercel/skills/vercel-connect/SKILL.md

## When to use it
- obtain scoped OAuth tokens for Slack, GitHub, or Snowflake via Vercel OIDC
- connect AI agents to external MCP endpoints
- generate integration code using the `@vercel/connect` SDK
- route incoming webhooks from Slack, Linear, or GitHub to agent apps

## Example prompts
- Set up a Slack connection using Vercel Connect to post messages as a bot
- Register an MCP server endpoint at https://mcp.linear.app/mcp with Vercel Connect
- Show how to fetch a GitHub token with @vercel/connect in TypeScript

# Vercel Connect Skill

## Overview

Vercel Connect enables to securely obtain scoped tokens for accessing third-party services on behalf of apps or users. It uses Vercel OIDC tokens to authenticate and exchange for Vercel Connect tokens via the Vercel API.

## When to Use Vercel Connect

Use Vercel Connect when you need to:

- Send messages via Slack (as a bot or on behalf of a user)
- Access GitHub repositories or APIs
- Connect to any third-party system that requires OAuth tokens or API credentials
- Obtain tokens for authenticated API calls

## Modes of tokens

The SDK supports three subject types — pick based on what's acting:

- **`user`** — actions performed on behalf of a specific end user (e.g., post a Slack message as the user). Requires a user `id` and optional `issuer`.
- **`app`** — actions performed as the app itself (e.g., post as a Slack bot, app-level GitHub access). No consent flow — fails terminally if the connector is not installed.
- **`jwt-bearer`** — RFC 7523 JWT-bearer exchange for connectors that accept a caller-minted assertion. Pass `sub` (required), plus optional `iss`, `aud`, and `additionalClaims`. Use when the third-party expects you to vouch for the subject via a signed JWT rather than an interactive OAuth grant.

## Available Tools

All tools have `--format=json` option for machine-readable output.
