Claude Desktop with Markup AI MCP

Chat

Overview

Markup AI is listed in Claude’s connector directory. Connect it to use the hosted Markup AI MCP server in Claude Desktop and on claude.ai without setting up a custom connector.

You’ll need a Markup AI account. If you don’t have one yet, you can create it while you connect.

Connect Markup AI

1

Open the Markup AI listing

Open the Markup AI directory listing. You can also open Claude → Settings → Connectors, click Browse connectors, and search for Markup AI.

2

Connect

Log in to Claude if you aren’t already, then click Connect. On a Team or Enterprise plan, an owner may need to enable the connector for your organization first.

3

Sign up or log in to Markup AI

After you click Connect, Claude redirects you to Markup AI.

  • New to Markup AI: Create your Markup AI account.
  • Already have an account: Log in to your Markup AI account.

Then click Allow Access to authorize the connector. After a few seconds, Claude returns and shows Markup AI as connected.

4

Verify

Start a new chat and ask Claude to use Markup AI. For example: Draft a blog post about migrating birds and then review it with Markup AI.

Test Your Setup

  • “Check this paragraph for brand-voice drift with Markup AI: [paste text]”
  • “Use Markup AI to show how a skeptical buyer would react to this copy: [paste text]”
  • “List the available Markup AI agents.”
  • “Draft a blog post about migrating birds and then review it with Markup AI.”

You should see Claude call Markup AI tools to analyze your text.

Troubleshooting

  • If you can’t connect on a Team or Enterprise plan, ask your organization owner to enable Markup AI.
  • If Claude doesn’t call Markup AI, click the + button in the message composer, open Connectors, and confirm Markup AI is turned on for the chat. Then mention Markup AI in your prompt.
  • If you previously added Markup AI as a custom connector, remove that connector after connecting from the directory to avoid seeing duplicate tools.
  • Fully quit Claude Desktop (Cmd+Q on macOS) and relaunch if tools don’t appear.

Add Markup AI as a Custom Connector

If you can’t connect from the directory, you can add the hosted Markup AI MCP server to Claude as a custom connector instead.

Custom connectors authenticate with OAuth login only—there’s no field for an API-key header. If you need to authenticate with an API key, use Claude Code instead.

1

Add a custom connector

  1. Open Claude Desktop → Settings → Connectors.
  2. Click Add custom connector.
  3. Fill in the details:
    • Name: Markup AI
    • Remote MCP Server URL: https://api.markup.ai/mcp/
  4. Click Add to save the connector.
At the time of writing, Claude Desktop may not automatically close the connector modal after saving. After clicking Add, the Markup AI connector is added to the list—you can click cancel to close the modal and continue.
2

Log in to Markup AI

  1. The Markup AI connector appears in your list in a disconnected state.
  2. Click Connect and click Allow Access in the browser window that opens.
  3. After a few seconds, Claude Desktop updates and shows Markup AI as connected.
3

Verify

Start a new chat and confirm the Markup AI tools are available.

If the connector stays disconnected, confirm the URL is https://api.markup.ai/mcp/, then click Connect again and complete the browser login. On a managed device, check your organization’s policy settings for connectors.
