# Codex

Install the Noelclaw MCP skill in OpenAI's Codex CLI. No build step - runs via `npx`.

**Requirement:** Node.js >= 18.

***

## Via `codex mcp add`

```bash
codex mcp add noelclaw -- npx -y -p @noelclaw/mcp@3.43.1 noelclaw-mcp
```

## Via Config File

Edit `~/.codex/config.toml` (or a project-scoped `.codex/config.toml`):

```toml
[mcp_servers.noelclaw]
command = "npx"
args = ["-y", "-p", "@noelclaw/mcp@3.43.1", "noelclaw-mcp"]
```

Restart Codex, then verify with `/mcp` in the TUI - `noelclaw` should show as active with all 121 tools loaded.

***

## Optional: With Environment Variables

```toml
[mcp_servers.noelclaw]
command = "npx"
args = ["-y", "-p", "@noelclaw/mcp@3.43.1", "noelclaw-mcp"]

[mcp_servers.noelclaw.env]
BANKR_API_KEY = "your-bankr-key"
```

See [Environment Variables](/reference/env-vars.md) for the full list.

***

## Test It

```
get_market_data
```

```
ask_noel question: "What's moving in crypto right now?"
```

***

## Run Memory Fully Local (Optional, Free)

By default, memory is stored via the Noelclaw-hosted proxy. To run it entirely on your own machine instead - private, zero cost, no account needed - run the setup wizard from a terminal:

```bash
npx -y -p @noelclaw/mcp@3.43.1 noelclaw setup
```

This walks you through bringing your own LLM key (Bankr, Anthropic, OpenAI, or a custom self-hosted endpoint) and enabling local memory, which auto-installs a free, open-source [supermemory](https://github.com/supermemoryai/supermemory) server on your machine. Restart Codex afterward - memory tools pick up the local server automatically. Check status with `npx -y -p @noelclaw/mcp@3.43.1 noelclaw doctor`.

## Troubleshooting

| Problem                      | Fix                                                                     |
| ---------------------------- | ----------------------------------------------------------------------- |
| Server not showing in `/mcp` | Restart Codex after editing `config.toml`                               |
| `npx: command not found`     | Install Node.js 18+ from [nodejs.org](https://nodejs.org)               |
| Slow first start             | `npx` downloads the package on first run. Subsequent starts are instant |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.noelclaw.fun/install-by-client/codex-install.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
