Connect claude.ai

This walks you through connecting claude.ai (in the browser) to Assemblified as a custom connector, so you can ask Claude about your bills of materials, sub-assemblies, and raw materials. This walkthrough shows the default read-only flow — the access level is chosen when you generate the connection code (see Connect claude.ai or ChatGPT).

Before you start

• An active Assemblified subscription (LLM / API Access is in open beta).
• A claude.ai account that supports adding a custom connector.

Step 1 — Generate your connection code in Assemblified

In Assemblified, generate the one-time code you’ll paste back into claude.ai at the end.

1. Open Settings → LLM / API Access.
2. In the Connect a web chat (claude.ai / ChatGPT) card, click Connect ChatGPT / Claude.
3. Copy the connector URL (it ends in /mcp-agent) and the one-time connection code. Both are valid for 10 minutes.

Copy the /mcp-agent URL and the one-time code from Settings → LLM / API Access.

Tip

Keep this Assemblified tab open — you’ll paste the code in Step 4, and the code expires after 10 minutes.

Step 2 — Add a custom connector in claude.ai

1. Go to claude.ai/customize/connectors (Customize → Connectors).
2. Click the + icon at the top of the Connectors panel.
3. Choose Add custom connector.

Connectors → + → Add custom connector.

Step 3 — Enter the connector details

1. Name: Assemblified.
2. URL: paste the /mcp-agent URL from Step 1 — https://assemblified.com/mcp-agent.
3. Leave the Advanced settings (OAuth Client ID / Secret) blank — they aren’t needed.
4. Click Add.

Name the connector and point it at the /mcp-agent URL.

Step 4 — Connect and approve read-only access

1. On the new Assemblified connector, click Connect.
2. Claude forwards you to Assemblified’s Connect to Assemblified screen at https://assemblified.com/mcp-agent.
3. Paste the connection code you copied in Step 1 and click Approve read-only access.

Paste the one-time code, then approve read-only access.

Note

Generated a read & write code instead? The same screen shows that scope and the button reads Approve read & write access — what write access covers is described in Operating BOMs & sub-assemblies and Operating raw materials & stock.

Once approved, you’re back in claude.ai and connected. The connector also shows up in the Connected apps table on the LLM / API Access page in Assemblified.

Try it out

Ask Claude something in plain language, such as “Which of my raw materials aren’t used in any BOM yet?” It reads the answer live from your store.

Code expired?

The connection code is single-use and lasts 10 minutes. If Claude says it’s invalid, generate a fresh one — see If the code expires.
