claude.ai (web)

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.
• 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

 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:

   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:

   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:

   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 connector stopped working after 30 days

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.

The MMW page rejects the key

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.

No Add custom connector option

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 or Claude Code with the local agent.
