# Set up the 3RD connector for Claude

> Step-by-step setup for the 3RD MCP connector in the Claude desktop app and in Claude Code — including API keys, permissions, and example queries.

The 3RD connector brings your brand's AI-search visibility data into Claude. Once connected, you can ask Claude about your visibility, citations, competitors, and playbook in plain language — and it answers using your live 3RD data.

## Before you start

You need a 3RD account with access to at least one brand. The connector signs you in with the same account you use at **app.get3rd.com** and only ever shows data for the brands you already have access to.

<Warning>
  If your account has no brands yet, the connector will connect but return no data.
</Warning>

## Set up

<Tabs>
  <Tab title="Claude web & desktop">
    **Recommended.** One-click sign-in — no API keys, no config files.

    <Steps>
      <Step title="Open the connector settings in Claude">
        In Claude, go to **Settings → Connectors** and choose **Add custom connector**.
      </Step>

      <Step title="Add the 3RD server URL">
        Give it a name (for example, "3RD") and paste this URL:

        ```text theme={null}
        https://app.get3rd.com/api/mcp
        ```
      </Step>

      <Step title="Sign in to 3RD">
        Click **Connect**. A 3RD sign-in window opens — log in with your usual 3RD account.
      </Step>

      <Step title="Approve access">
        Review the access request and click **Approve**. You're granting Claude **read** access to your 3RD profile and brand data — revocable any time (see below).
      </Step>

      <Step title="Start using it">
        The 3RD connector now appears in Claude. Enable it in a chat and ask away.
      </Step>
    </Steps>
  </Tab>

  <Tab title="Claude Code (CLI)">
    For the terminal, authenticate with an API key instead of the browser sign-in.

    <Steps>
      <Step title="Create an API key in 3RD">
        Open [app.get3rd.com](https://app.get3rd.com), go to the **MCP** page in the sidebar, open the **API Keys** tab, and create a key.

        <Warning>Copy the key right away — you won't be able to see it again.</Warning>
      </Step>

      <Step title="Register the server">
        Run this in your terminal, replacing `YOUR_API_KEY` with the key you just created:

        ```bash theme={null}
        claude mcp add --transport http third-law https://app.get3rd.com/api/mcp \
          --header "Authorization: Bearer YOUR_API_KEY"
        ```
      </Step>

      <Step title="Verify">
        ```bash theme={null}
        claude mcp list
        ```

        You should see `third-law` connected.
      </Step>
    </Steps>
  </Tab>
</Tabs>

## Try it

Once connected, ask Claude things like:

* "How visible is my brand in AI answers this month?"
* "Which competitors outrank me, and on which topics?"
* "What are my top citation sources right now?"
* "Where are my biggest content gaps?"
* "What's on my playbook this week?"

## What the connector can access

Every tool is **read-only** — the connector reads your 3RD data and never changes it.

| **Setup & documents**       | Brands, competitors, markets & audiences · Monitored pages & brand profile · Search and fetch your documents |

## Manage or disconnect access

You can remove the connector at any time from Claude's **Settings → Connectors** screen. Revoking access there immediately stops Claude from reading your 3RD data.

For the CLI:

```bash theme={null}
claude mcp remove third-law
```

Then revoke the API key from the **API Keys** tab in 3RD.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Claude connects but returns no data">
    Your 3RD account needs access to at least one brand. Open [app.get3rd.com](https://app.get3rd.com) and confirm you can see a brand there, then try again.
  </Accordion>

  <Accordion title="&#x22;Invalid API key&#x22; in Claude Code">
    Make sure you replaced `YOUR_API_KEY` with a real key and that the key hasn't been revoked or expired. Create a fresh key from the **API Keys** tab and re-run the command.
  </Accordion>

  <Accordion title="The connector doesn't appear after adding it">
    Fully quit and reopen Claude, then check **Settings → Connectors**. If sign-in didn't complete, remove the connector and add it again.
  </Accordion>
