Install The CALL-E Codex Plugin

The Codex plugin provides the $calle skill. It uses the shared calle CLI instead of configuring Codex to connect directly to the remote MCP server.

Prerequisites

The official marketplace install command requires codex-cli >= 0.122.0. Check your version with:

codex --version

You do not need to install the shared CLI globally before installing the plugin. The plugin uses the repository-local CLI when available, then a global calle command when available, then falls back to npx -y @call-e/cli.

To authenticate before installing or using the plugin:

npx -y @call-e/cli auth login

Install

Add the latest released Codex marketplace from this repository:

codex plugin marketplace add CALLE-AI/call-e-integrations \
  --ref '@call-e/codex-plugin@latest' \
  --sparse .agents/plugins \
  --sparse packages/codex-plugin/plugin

@call-e/codex-plugin@latest is a Git tag updated by the release workflow after @call-e/codex-plugin publishes. For a reproducible install, replace it with a package-level release tag such as @call-e/codex-plugin@<version>.

Open Codex, run /plugins, choose the CALL-E marketplace, and install CALL-E.

If you are pinned to a Codex CLI older than 0.122.0 and cannot use codex plugin marketplace add, upgrade Codex when possible. As a manual fallback, add the equivalent sparse payload from the same Git ref to your workspace root:

.agents/plugins/marketplace.json
packages/codex-plugin/plugin/

Keep those paths exactly as shown so the marketplace entry can resolve ./packages/codex-plugin/plugin.

Use

After installing the plugin, invoke:

$calle

Codex will use CALL-E for setup checks, authentication recovery, call planning, planned call execution, and call status checks.

ChatGPT App Boundary

If you also have a CALL-E ChatGPT App or connector installed in Codex, disable that App for sessions where $calle should use the Codex plugin path:

[apps.<app-id>]
enabled = false

To disable all ChatGPT Apps/connectors in a Codex profile:

[features]
apps = false

The plugin itself does not configure Codex to connect directly to the remote MCP server and its skill tells Codex not to call ChatGPT App/connector tools while the plugin is active. Disabling the App in Codex configuration is still the hard isolation boundary.
