How to connect Datadog to Codex

  • Codex gets 35 Datadog tools through one Metorial MCP URL.
  • Setup is 3 steps; teammates then sign in with SSO.
  • You need the Codex CLI, IDE extension or ChatGPT desktop app.

What Codex can do with Datadog

Ask your agent in plain language. Each of these maps to a real tool on the server.

  • Ask Codex to use the list hosts tool in Datadog
  • Ask Codex to use the manage slo tool in Datadog
  • Ask Codex to use the list monitors tool in Datadog
  • Ask Codex to use the list active metrics tool in Datadog
  • Ask Codex to use the get incident tool in Datadog

Add the Datadog MCP server to Codex

Run these once. Afterwards, everyone you give access to signs in the same way.

  1. 1. Enable Datadog in Metorial

    In your Metorial portal, enable the Datadog MCP server and sign in with the account that owns the data. Access stays governed by your team policies.

  2. 2. Add the server and sign in

    The Codex CLI, IDE extension and ChatGPT desktop app share this config.

    codex mcp add metorial --url <your-magic-mcp-url>
    codex mcp login metorial
  3. 3. Check the connection

    Type /mcp in Codex to see Metorial and its Datadog tools.

Give your team Datadog in Codex

Once Datadog is enabled in Metorial, teammates sign in with SSO and get the same connection in Codex, with only the tools their role allows.

One link covers every app you approve. See how the MCP gateway handles access, roles and audit logs for the whole company.

Using Datadog tools in Codex

What to expect once Datadog is connected.

  • Limit which Datadog tools Codex sees with enabled_tools and disabled_tools on the metorial server in config.toml.
  • Set default_tools_approval_mode to auto, prompt, writes or approve. writes prompts only for tools that are not marked read-only.
  • Type /mcp in the composer to see the connected servers.
  • Override the approval behavior for a single Datadog tool with tools.<tool>.approval_mode.

Troubleshooting Codex

Metorial is listed but tools are missing
Codex can connect without credentials and then see nothing. Run codex mcp login metorial to complete the OAuth sign-in.
Metorial times out at startup
Codex waits 10 seconds by default. Raise startup_timeout_sec under [mcp_servers.metorial] in ~/.codex/config.toml.
Long tool calls fail after a minute
The default tool timeout is 60 seconds. Raise tool_timeout_sec for the metorial server in config.toml.

Based on the Codex MCP documentation.
