# claude.ai (web)

> Add MMW to Claude on the web as a custom connector over OAuth, with nothing to install.

On this page you will add MMW to claude.ai as a custom connector, see what happens to your key along the way, and verify the connection.

## What you get

- The `remember`, `search`, `forget`, `validate_memory` and `gateway_call` tools in claude.ai conversations.
- The same memory that Claude Code, Cursor and Codex see with a key from the same account and project.
- Nothing to install: the connection is made from the browser over OAuth.

The local agent does not run in the web app, so there is no `mmw_sync_status` and no session history upload here.

## Prerequisites

- An MMW API key (starts with `mmw_`); see the [Quickstart](/start/quickstart/).
- A claude.ai account that can add custom connectors. Whether this is available depends on your Claude plan and your organization's Claude settings.

## How sign-in works

```text
 claude.ai                          MMW
 ─────────                          ───
 Add custom connector  ─────────►   MMW authorization page
                                    you paste your API key → Allow
 Claude's own token    ◄─────────   OAuth (client registration, PKCE)
 (valid for 30 days)
```

Your API key stays with you: claude.ai receives a separate token, not the key.

## Setup

1. On claude.ai open Settings → Connectors and choose Add custom connector.

2. Enter a name such as `MMW` and the URL:

   ```text
   https://mcp.mmwhub.tech/mcp
   ```

3. Choose Connect. The MMW authorization page opens.

4. Paste your API key and choose Allow. You return to claude.ai with the connector connected.

5. In a conversation open the tools menu below the input box and make sure the MMW connector is enabled.

## Verify

1. In the tools menu the MMW connector should list `remember`, `search`, `forget`, `validate_memory` and `gateway_call`.

2. Ask:

   ```text
   Remember in MMW: staging is deployed with the systemd unit app-staging. Fact key: deploy-staging.
   ```

   Claude may ask for permission to call `remember`, then confirms the record was saved.

3. In a new conversation ask:

   ```text
   How do we deploy staging? Check MMW.
   ```

   Expected answer: Claude calls `search` and replies that staging is deployed with `app-staging`. If you saved the same fact earlier from Claude Code with a key for the same project, it shows up here too.

## Common problems

The token MMW issued to claude.ai is valid for 30 days. Reconnect the connector in Settings → Connectors and paste your key on the MMW page again.

Check that you copied the whole key, that it starts with `mmw_` and that it has not been revoked in your account. If the key is lost, issue a new one.

Custom connectors are not available on every Claude plan, and an organization admin may disable them. Check Claude's help or ask your admin. Alternatives: [Claude Desktop](/clients/claude-desktop/) or [Claude Code](/clients/claude-code/) with the local agent.
