Connect Claude to Nylon

Add Nylon to Claude once and it’s available in Claude on the web, Claude Desktop and Cowork.

Before you start

• A Nylon Adviser or Elite seat.
• Any Claude plan. The Free plan allows one custom connector.
• On Team, an Owner or Primary Owner adds the connector for the organisation first. On Enterprise, so can anyone with a custom role that includes managing Libraries.

Connect

Free, Pro or Max

1. In Claude, open Customize → Connectors.

2. Choose + Add, then Add custom connector.

3. Enter a name (Nylon) and the URL, then choose Continue:

   https://mcp.usenylon.com/mcp

4. Review the detected authentication settings and choose Continue.

5. Under Authentication, choose Sign in now.

6. Under OAuth client, choose Register automatically.

7. Choose Add. Claude opens Nylon’s sign-in page.

8. Sign in to Nylon and choose Allow access.

Team or Enterprise

1. Owner: open Organization settings → Connectors and choose Add. Hover over Custom and choose Web.

2. Owner: enter a name (Nylon) and the URL https://mcp.usenylon.com/mcp, then choose Continue.

3. Owner: review the detected authentication settings and choose Continue. Under OAuth client, choose Register automatically, then choose Add.

4. Each member: open Customize → Connectors, find Nylon and choose Connect.

5. Each member: sign in to Nylon with your own account and choose Allow access.

Choose “Register automatically”

Claude recommends Use Claude’s published identity. Nylon’s sign-in doesn’t support that option today, so choose Register automatically.

What you’ll see when you sign in

Nylon’s consent screen reads “Claude wants to connect to your Nylon account”. It lists what Claude can do (search Nylon’s library of cases and legislation, and read the full text of a document) and what it can’t (access your chat history, folders or saved work; change account, billing or team settings; upload, edit or delete anything). Choose Allow access to finish.

Use it in a chat

In a chat, choose +, then Connectors, and make sure Nylon is switched on. Then ask:

Using Nylon, when must a business register for GST in New Zealand? Cite the sections of the Goods and Services Tax Act 1985.

Claude searches Nylon, reads the relevant sections and links each citation to Nylon.

Troubleshooting

Problem	Fix
“Upgrade to Adviser” on the consent screen	Your seat is Starter. Ask your Nylon admin for an Adviser or Elite seat, then connect again.
“AI tool connections are turned off for your account”	Your admin has switched off Allow AI tool connections. Ask them to turn it on in Organisation Settings → Connections.
Sign-in fails straight after adding the connector	Remove the connector and add it again, choosing Register automatically under OAuth client.
Claude answers without citing Nylon	Check Nylon is switched on under + → Connectors, and start the prompt with “Using Nylon”.
Citation links ask you to sign in	That’s expected. Links open Nylon’s source viewer, which needs a Nylon account.

To disconnect, open Customize → Connectors and remove Nylon (Team and Enterprise owners can also use Organization settings → Connectors). See Security and data and Troubleshooting.
