Codex Exa

English | 简体中文

A Git-backed Codex Marketplace for current web search and full-page retrieval through the official Exa MCP service.

This is a community-maintained integration and is not an official Exa release.

Plugin	Purpose	Requirements

Add This Marketplace to Codex

Desktop app

1. Open Codex → Plugins.

2. Open the Marketplace source menu beside the plugin search field and select + Add More.

   

3. Paste this repository URL:

   https://github.com/zlsbksdxl/codex-exa.git
   

   

4. Select Codex Exa, open exa, and install it.

Use the Git repository URL, not a raw marketplace.json URL. Codex clones the repository and discovers .agents/plugins/marketplace.json automatically.

CLI

codex plugin marketplace add \
  'https://github.com/zlsbksdxl/codex-exa.git' \
  --ref main \
  --sparse '.agents/plugins' \
  --sparse 'plugins'

codex plugin list --marketplace codex-exa --available --json
codex plugin add exa@codex-exa

Fully restart the ChatGPT/Codex desktop app after installation, then use a new task so the Skill and MCP server are reloaded.

Connect Exa

The plugin uses Exa's official remote MCP OAuth endpoint. During installation, or the first time Exa is used, Codex opens an account connection flow. Sign in to Exa and approve access; no API key is stored in this repository or plugin configuration.

Update

codex plugin marketplace upgrade codex-exa
codex plugin add exa@codex-exa

Migrating from the Former Combined Marketplace

The original codex-plugins Marketplace was split into this repository and codex-lark. If the former Marketplace is still configured, remove its installed plugins and source before adding the two new repositories:

codex plugin remove exa@codex-plugins
codex plugin remove feishu2codex@codex-plugins
codex plugin marketplace remove codex-plugins

Then add codex-exa using the commands above and add codex-lark from its own README.
