# Install the Graphon plugin

Give your coding agent the Graphon MCP server, the graphon CLI, and Graphon skills with one install.

The plugin adds the Graphon MCP server (OAuth on the first call), the
`graphon` CLI (local files, folder uploads, and API keys that never reach
the transcript), and Graphon skills.

## Install

Run the commands for the agent in a terminal, then start a new agent
session so the plugin loads.

### Claude Code (Verified)

```bash
claude plugin marketplace add GraphonAI/graphon-plugin
claude plugin install graphon@graphon --scope user
```

### Codex (Verified)

```bash
codex plugin marketplace add GraphonAI/graphon-plugin
codex plugin add graphon@graphon
```

### Cursor (Verified)

```bash
npx plugins add GraphonAI/graphon-plugin
```

A Cursor marketplace listing is pending review.

### Gemini CLI (Blocked upstream)

```bash
gemini extensions install https://github.com/GraphonAI/graphon-plugin --consent
```

Gemini Code Assist no longer signs in individual accounts, so the extension installs but cannot connect. Skills still work through `npx skills add`.

### Antigravity IDE (Verified)

```bash
npx skills add GraphonAI/graphon-plugin
```

Copy mcp/antigravity.json to ~/.codeium/antigravity/mcp_config.json, restart, then sign the server in from the MCP panel: Antigravity does not prompt for that on its own. The tools work once signed in. The skills load but this agent does not reliably follow their stop rules, so approve its commands one at a time. The Antigravity CLI does not surface MCP tools yet.

### Copilot CLI (Verified)

```bash
copilot plugin marketplace add GraphonAI/graphon-plugin
copilot plugin install graphon@graphon
```

If MCP tools are missing, your organization may block third-party MCP servers. Check github.com/settings/copilot. The skills work either way.

### Another agent (Should work)

```bash
npx plugins add GraphonAI/graphon-plugin
npx add-mcp https://api.beta.graphon.ai/mcp
```

## Sign in

Ask the agent to connect to Graphon. It signs in to the MCP server and to
the CLI in the browser. If Graphon is not signed in, sign in to the
`graphon` MCP server from the agent's MCP settings. In Claude Code, run `/mcp`.

Without the plugin, add the MCP server from [Connect](/mcp.md) and the CLI
from [Install & login](/cli.md).
