description	Configures or troubleshoots the Datadog MCP server `datadog`. Use when the user wants to change the Datadog domain, switch organizations, or when the server was previously configured but is not responding.

Datadog MCP Server

The id of the Datadog MCP Server referenced on this document is datadog. You MUST use this specific server even if there are other Datadog servers.

Shared reference

Read references/mcp-settings.md before proceeding. It contains the datadog-server-state check, registration file location, editing rules, and site-to-domain mapping used by the flows below.

Entry flow

Check the datadog-server-state (see mcp-settings.md). Use the datadog://mcp/whoami resource on the datadog server as the MCP call (do NOT use any other Datadog MCP server). Do not output anything until the datadog-server-state and resource content are available, and proceed based on the results:

• datadog-server-state=working and valid content — without any preamble, immediately show the user their current connection (from whoami): user name and email, organization name, and site (the dd_site value). Then let the user choose between using a different Datadog MCP domain or site or switching to a different Datadog organization.
• datadog-server-state=not-setup — without any preamble, tell the user the plugin is not set up and instruct them to run /ddsetup, and stop.
• datadog-server-state=not-working or not valid content — without any preamble, tell the user the server is configured but not working and go to the Troubleshooting Flow.

When communicating with the user below, describe the server state and actions in plain language. Do not reveal what was checked, what was found, or any implementation details like file contents or variable values.

Troubleshooting Flow

The server is configured but not responding. Read the current domain from the registration file (see mcp-settings.md for the file format and how to find the domain), then present the user with the likely causes — do not follow these sequentially, show them all and use judgment:

• Domain issue. Compare the domain against the site-to-domain table in mcp-settings.md. Only flag it as suspicious if it looks like a typo or a clearly malformed URL (e.g. mcp.us5.datadog.com missing the hq). A domain not in the standard table is not necessarily wrong — the user may be using a valid non-standard domain.

• Authentication. The authentication may have expired or was never completed, and the user needs to follow these steps:

  In Copilot:

  1. Run the command /mcp and select the datadog server
  2. Press r to reauthenticate

  In VS Code:

  1. Open the Command Palette (⌘⇧P on Mac or Ctrl+Shift+P on Windows/Linux — show the correct shortcut for the current operating system)
  2. Run the MCP: List Servers command and select the datadog server
  3. Click Restart Server — VS Code will prompt for authentication

• Network or access. The user's network may be blocking the connection, or their Datadog account may not have API access, like not having the MCP Read permission.

If the domain looks wrong, suggest running the Domain Flow to correct it.

Domain Flow

Changes the Datadog MCP domain the server connects to.

1. Show the current domain information (from whoami → dd_site if available, or from the current domain in the registration file — see mcp-settings.md for the file format). Present it in plain language (e.g. "the plugin is currently connected to …") — follow the "Stay on script" rule in mcp-settings.md.

2. Ask for the new domain. Present the available sites and their MCP domains from mcp-settings.md, and ask which domain to switch to. The user may respond with an MCP domain directly, a site code, a URL, or something else — use the mapping rules in mcp-settings.md to resolve the answer. Ask for clarification if ambiguous.

   Follow the "Stay on script" rule in mcp-settings.md. In particular, do not preview the follow-up instructions from step 4 below (reload, re-authenticate, etc.) — that step emits them verbatim at the right moment.

3. Edit the domain in the registration file following the editing rule in mcp-settings.md.

   Before (example):

   "url": "https://mcp.datadoghq.eu/api/..."
   

   After (switching to us1):

   "url": "https://mcp.datadoghq.com/api/..."
   

4. Tell the user the domain has been changed and to follow these steps:

   In Copilot:

   1. Run the command /mcp and select the datadog server
   2. Press r to reauthenticate

   In VS Code:

   1. Open the Command Palette (⌘⇧P on Mac or Ctrl+Shift+P on Windows/Linux — show the correct shortcut for the current operating system)
   2. Run the MCP: List Servers command and select the datadog server
   3. Click Restart Server
   4. Authenticate the Datadog MCP Server when prompted

Organization Flow

Switches to a different Datadog organization. The agent cannot do this automatically — the user must select the target organization in the browser.

Ask the user if they want to use an organization on the same domain or on a different domain.

• If on the same domain:

  • The user needs to reauthenticate and, during sign-in, choose the target organization in the browser, using the following steps:

    In Copilot:

    1. Run the command /mcp and select the datadog server
    2. Press r to reauthenticate

    In VS Code:

    1. Open the Command Palette (⌘⇧P on Mac or Ctrl+Shift+P on Windows/Linux — show the correct shortcut for the current operating system)
    2. Run the MCP: List Servers command and select the datadog server
    3. Click Restart Server — VS Code will prompt for authentication; choose the target organization during sign-in

• If on a different domain:

  • Run the Domain Flow telling the user to choose the target organization in the browser during sign-in.
