Plugins

Download Omnodex plugins here without signing in to the hosted dashboard. The downloads are public and available to Free users. Your agent app’s own plan requirements still apply.

Plugins connect your agent to the Omnodex MCP proxy. For Claude Code, Codex and Antigravity you do not need these downloads: omnodex install downloads the right version, checks it and installs it (see Installation). Use them to install by hand, or to install offline with omnodex install <agent> --plugin --from <file>. Either way, install Omnodex on the host where the agent runs first; the plugin does not include the Omnodex runtime.

Each version’s checksum is published next to it, and every version is listed in https://downloads.omnodex.com/plugins/<platform>/versions.json (cowork, codex or antigravity).

Claude Code

Claude Code needs no download:

omnodex install claude-code

This installs the hooks and the Omnodex plugin, the same omnodex-cowork package Cowork uses, for your user. Follow Claude Code Setup for verification.

Claude Cowork

Download omnodex-cowork.plugin.

Install the file in Settings > Plugins, or drag it onto the Cowork window. Follow Cowork Desktop Setup to configure the proxy and connect it to your dashboard. The proxy runs on your linked desktop, including for Cowork tasks started from the cloud.

ChatGPT Desktop: OpenAI Codex

Download	Use
omnodex-codex.zip	Unpack for the local marketplace installation
omnodex-codex.plugin	The same archive with a .plugin extension

Follow OpenAI Codex Setup to install from a personal marketplace in ChatGPT Desktop. This packages the Omnodex MCP server as a plugin; install project hooks separately for shell commands, edits, and session events. Codex CLI and IDE sessions on the same host use the same Codex configuration.

This download is for local Codex sessions. It does not add monitoring to ordinary ChatGPT chats, ChatGPT Work, or Codex on the web.

Google Antigravity

Download	Use
omnodex-antigravity.zip	Unpack for the Desktop App or agy CLI
omnodex-antigravity.plugin	The same archive with a .plugin extension

Follow Google Antigravity Setup for the Desktop App, agy CLI, and standalone IDE. Install project hooks separately to record completed tool calls, or use the direct MCP setup to capture routed MCP calls.

Other MCP clients

Use MCP Proxy for Any Client to register Omnodex directly in another MCP client. No surface-specific plugin is required.

Versions and updates

These links always download the latest published plugin. The release manifest lists each plugin’s version, archive size, SHA-256 checksum, and links to specific versions. The .plugin and .zip downloads for a surface contain identical bytes.

Updating your Omnodex runtime and updating a plugin are separate steps. See Updating Omnodex, then follow the update instructions for Cowork, Codex, or Antigravity.
