Site Scanner MCP Server — Claude setup guide

Connect Claude to Evinced Site Scanner MCP and ask Claude about your accessibility scan results in plain language. An Owner adds the connector once; then each person connects their own Evinced account.

The setup at a glance

Part 1 · Add the connector

Claude organization Owner, once

1. Open Connectors
2. Choose Custom › Web
3. Enter the name and URL
4. Keep the defaults
5. Check it’s listed

Part 2 · Start using it

Everyone, once each

6. Connect your Evinced account
7. Turn it on in a chat
8. Confirm the connection
9. Ask a real question

You need the Owner role in a Claude Team or Enterprise organization, an Evinced Site Scanner account, and about 5 minutes.

On Claude Pro or Max?

Add the connector yourself: Customize › Connectors › + › Add custom connector, with the same name and URL.

What you’ll enter

Every value used in steps 3 and 4. Copy them exactly.

Field	Value
Name	Evinced Site Scanner
MCP server URL	https://site-scanner-mcp.evinced.io/mcp
OAuth client ID (Advanced settings)	Leave empty
OAuth client secret (Advanced settings)	Leave empty
Browser sign-in	On

Good to know

• Nothing else to configure. The Site Scanner server sets up sign-in with Claude on its own, so the OAuth client fields stay empty.
• Everyone signs in as themselves. Each person connects their own Evinced account (step 6) and sees only what that account can access.
• One tool makes changes. Every tool only reads your Evinced data except Create Property, which adds a property to your account. An Owner can turn it off for the organization (step 5).
• Claude may ask before using a tool. The first time Claude uses a Site Scanner tool it can ask for your approval. Choose Allow, or Always allow for tools you trust.

Part 1 · Add the connector

A Claude organization Owner does this once.

Step 1 · Open Connectors

Adding a connector for your whole organization takes the Owner role.

1. In Claude, open Organization settings › Connectors.
2. Click + Add.

Step 2 · Choose Custom › Web

The Site Scanner server is hosted online, so it’s a Web connector.

1. Hover Custom.
2. Click Web.

Note

Desktop is only for extensions installed on a computer.

Step 3 · Enter the name and URL

The Add custom connector dialog opens.

1. Name: Evinced Site Scanner

2. MCP server URL:

   https://site-scanner-mcp.evinced.io/mcp

3. Click Continue.

Step 4 · Keep the defaults

Claude then shows the connector’s settings. There’s nothing to change.

1. Advanced settings: leave OAuth client ID and OAuth client secret empty.
2. Authentication: keep Browser sign-in on, so each person signs in with their own Evinced account.
3. Click Add.

These settings, as shown for the added connector

Step 5 · Check it’s listed

Evinced Site Scanner now appears in your organization’s connectors as a Web, Custom connector.

1. Search for Evinced to find it.
2. Click it any time to review its settings or limit which tools people can use.

Part 2 · Start using it

Everyone does this once, each with their own Evinced account.

Step 6 · Connect your Evinced account

1. Open Customize › Connectors, search for Evinced Site Scanner, and click + on its card.

   

2. Sign in with your Evinced account.

   

3. Back in Claude, the card shows a check: you’re connected.

   

Step 7 · Turn it on in a chat

Connectors can be switched on or off for each chat.

1. In the message box, click +.
2. Open Connectors.
3. Make sure Evinced Site Scanner is switched on.

Step 8 · Confirm the connection

The whoami tool only reads. It’s the quickest way to check which account Claude is using.

1. Ask:

   Use the Evinced Site Scanner connector to run its whoami tool.

2. Claude notes it used Evinced Site Scanner and replies with your Evinced account and tenant.

Note

If Claude asks for approval to use the tool, choose Allow.

Step 9 · Ask a real question

Ask in plain language. Claude picks the Site Scanner tool that fits.

1. Ask about your sites, for example:

   List my Evinced Site Scanner properties with their latest scan date and score.

2. Claude runs the matching tool (here, List properties) and answers from your live Site Scanner data.

If something goes wrong

What you see	What to do
No “Custom” option when you click Add	Only Owners can add custom connectors to an organization. Ask an Owner to do Part 1. On Pro or Max, add it yourself from Customize › Connectors.
Evinced Site Scanner isn’t listed in Customize › Connectors	An Owner hasn’t added it yet, or your role doesn’t have access to it. Ask an Owner to check the connector’s Roles with access.
Claude doesn’t use Site Scanner in a chat	Turn the connector on for that chat: + › Connectors › Evinced Site Scanner (step 7).
Wrong Evinced account after you connect	Open the connector, choose ⋮ › Disconnect, then connect again. The sign-in asks for your credentials each time. Don’t choose Remove from your team: that removes it for everyone.

Still stuck?

Email support@evinced.com and include the connector URL, https://site-scanner-mcp.evinced.io/mcp.

That’s it

Evinced Site Scanner is ready in Claude. Each person connects their own Evinced account once.
