# Set Up the Claude Version Story Redlining Connector > Add Version Story as a connector to get our best-in-class comparisons directly in Claude. ## Quick copy Our MCP URL: ``` https://mcp-compare.versionstory.com/mcp ``` Add this to your allowed domains: ``` *.versionstory.com ``` Paste this into your default prompt: ``` When I ask you to compare or redline documents, use Version Story Compare. ``` Jump to: - [For your organization](#for-your-organization): an owner adds the connector once, for everyone. - [As a member of an organization](#as-a-member): connect your own account once an owner has added it. - [For a UK organization](#for-a-uk-organization): the same, with the UK connector, so your documents stay in the UK. ## Add the connector 1. In Claude, open **Customize** in the sidebar, then the **Connectors** tab. 2. Click **Add**, then **Add custom connector**. Fill in the two fields and click **Continue**: Name: ``` Version Story Compare ``` MCP URL: ``` https://mcp-compare.versionstory.com/mcp ``` ![The Add custom connector dialog with the name and URL filled in](https://www.versionstory.com/help/claude-connector/add-dialog.199f9816.jpg) 3. Claude checks the server. If it asks how members sign in, choose **Sign in now** under **Authentication**, and **Register automatically** under **OAuth client**. Version Story does not use Claude's published identity, so leave that option, even though Claude marks it recommended. Click **Add**. ![Authentication set to Sign in now, and OAuth client set to Register automatically](https://www.versionstory.com/help/claude-connector/auth-oauth.3ad2b1bf.jpg) 4. On the connector's page, click **Connect**. Sign in to Version Story if you are not already signed in, then click **Authorize**. You are returned to Claude. 5. Under **Tool permissions**, set all three groups, **Interactive tools**, **Read-only tools** and **Write/delete tools**, to **Always allow** using the menu to the right of each. On any other setting Claude stops to ask before each step of a comparison. ![Tool permissions with all three groups set to Always allow](https://www.versionstory.com/help/claude-connector/tool-permissions.dc2875bb.jpg) ## Allow network access Claude moves your documents to Version Story and brings the finished redlines back, so it needs to reach Version Story. 1. Open **Settings → Capabilities**, and under **Code execution and file creation** make sure **Run code in the cloud** is on. The network setting has no effect while it is off. 2. Turn on **Allow network egress**. 3. Under **Additional allowed domains**, enter this domain and click **Add**: Allowed domain: ``` *.versionstory.com ``` ![Run code in the cloud and Allow network egress on, with the domain in the allowlist](https://www.versionstory.com/help/claude-connector/shared-capabilities-network.c2511fa2.jpg) ## Tell Claude when to use it Open **Settings → Account**, and under **Instructions for Claude** add this line, so Claude reaches for Version Story whenever you ask for a comparison without your having to name it: Instructions for Claude: ``` When I ask you to compare or redline documents, use Version Story Compare. ``` ![The comparison line in Instructions for Claude](https://www.versionstory.com/help/claude-connector/shared-instructions.94331de3.jpg) ## Test it Start a new conversation, attach two versions of a document, and ask Claude to redline them. Claude returns the PDF redline, previewed in the conversation, and a link to the interactive redline in Version Story. [Compare Documents in Claude](/help/compare-documents-in-claude) has more to try. If a comparison fails with a host-allowlist error, network access is not set up: the domain is missing, the egress toggle is off, or **Run code in the cloud** is off.

For your organization

 An owner of your Claude organization adds the connector and sets the organization's capabilities once, for everyone. Then each member connects their own Version Story account, so every redline lands in the right person's projects. ### Add the connector 1. Open **Organization settings → Connectors**. 2. Click **Add**, then **Custom → Web**. Fill in the two fields and click **Continue**: Name: ``` Version Story Compare ``` MCP URL: ``` https://mcp-compare.versionstory.com/mcp ``` 3. Choose **Sign in now** under **Authentication**, and **Register automatically** under **OAuth client**, then click **Add**. **Sign in now** is what you want: each member signs in to their own Version Story account. The connector's **Tools** tab sets a ceiling on what members may choose. Its default lets them choose **Always allow**; leave it there, or members cannot let a comparison run start to finish. ### Set the organization's capabilities Both settings are in **Organization settings → Capabilities**. 1. Under **Tool approvals**, turn on **Allow "Always allow" for connector tools**, so members can set the connector's tools to run without asking each time, and **Allow "Skip all approvals" mode**. ![Tool approvals with Skip all approvals mode and Always allow for connector tools turned on](https://www.versionstory.com/help/claude-connector/org-tool-approvals.babb3657.jpg) 2. Under **Code execution**, turn on **Cloud code execution and file creation** and **Allow network egress**, then add this domain under **Additional allowed domains**: Allowed domain: ``` *.versionstory.com ``` ![Code execution and network egress on, with the domain in the organization's allowlist](https://www.versionstory.com/help/claude-connector/org-capabilities-network.0eef2812.jpg) Then each member connects their own account: [As a member of an organization](#as-a-member).

As a member of an organization

 Once an owner has added the connector for your organization: 1. Open **Customize** in the sidebar, then the **Connectors** tab. The connector your owner added is listed under **Yours**. Click it. 2. Click **Connect**. Sign in to Version Story if you are not already signed in, then click **Authorize**. You are returned to Claude. 3. Under **Tool permissions**, set all three groups to **Always allow**, as in [Add the connector](#add-the-connector). 4. Under **Settings → Account → Instructions for Claude**, add the line from [Tell Claude when to use it](#tell-claude-when-to-use-it).

For a UK organization

 An organization whose Version Story account is in the UK, the one you sign in to at [uk.versionstory.com](https://uk.versionstory.com), uses the UK connector. It keeps your documents and redlines in the UK, and members sign in with their UK Version Story accounts. Copy this URL instead of the one at the top of the page: UK MCP URL: ``` https://mcp-compare-uk.versionstory.com/mcp ``` Everything else is as [For your organization](#for-your-organization) and [As a member of an organization](#as-a-member) describe, with two differences: - **The owner** pastes the UK URL above as the **MCP server URL**. The `*.versionstory.com` domain already covers the UK connector and the UK sign-in page. - **Each member** signs in at `uk.versionstory.com` when they click **Connect**, with their UK account. Redline links then open at `uk.versionstory.com`. Version Story keeps its side in the UK. Where Claude itself processes your conversations is set in your Claude organization, separately. If the sign-in page asks for an account a member does not have, the connector was added with the US URL: an owner should remove it and add it again with the UK URL.
