Step 1 is required for the app UI. Mem0 isn't in OpenAI's curated directory yet, so **without `codex plugin marketplace add`, Mem0 won't appear in the Codex app's Plugin Directory** — searching for it returns nothing. Adding the marketplace surfaces it (under **Created by you**) and makes it installable.

Do not combine with Option B. The plugin manifest auto-registers the `mem0` MCP server, so adding both will create a duplicate registration.

The fastest way to connect Codex to Mem0 — no plugin, no marketplace. Add the MCP server with a single command:
```bash
codex mcp add mem0 --url https://mcp.mem0.ai/mcp/ --bearer-token-env-var MEM0_API_KEY
```
Or add it manually to `~/.codex/config.toml`:
```toml
[mcp_servers.mem0]
url = "https://mcp.mem0.ai/mcp"
url = "https://mcp.mem0.ai/mcp/"
bearer_token_env_var = "MEM0_API_KEY"
```
Make sure `MEM0_API_KEY` is exported in the shell you launch Codex from, then restart Codex.
<Info>
Codex's `codex mcp add` CLI only supports stdio MCP servers. Because Mem0's MCP is HTTP/streamable, you configure it by editing `config.toml` directly (or via the **Plugins → Connect to a custom MCP → Streamable HTTP** UI in the Codex app).
</Info>
This gives you the MCP tools but not the lifecycle hooks or SDK skill.
### Managing the Plugin
```bash
codex plugin marketplace upgrade # pull latest plugin versions
codex plugin marketplace remove mem0-plugins # unregister the marketplace
codex plugin remove mem0@mem0-plugins # uninstall the plugin (keeps the marketplace)
codex plugin marketplace remove mem0-plugins # unregister the marketplace entirely
```
To update, run `codex plugin marketplace upgrade` to pull the latest from the Mem0 repo.
