+1. Configure your AI agent to send the following headers with each request to the server URL:
+
+    - **Authorization:** `Bearer PERSONAL_ACCESS_TOKEN`
+    - **x-axiom-org-id:** `ORGANIZATION_ID`
+
+    <Info>
+    Replace `PERSONAL_ACCESS_TOKEN` with the personal access token you have generated.
+
+    Replace `ORGANIZATION_ID` with the organization ID.
+    </Info>
+
+    If your AI agent only supports setting the Authorization header, pass the organization ID as a URL parameter: `https://mcp.axiom.co/mcp?org-id=ORGANIZATION_ID`
