Use --port to also expose a local HTTP debug API on `127.0.0.1:`. Select a Datum context with exactly one of --organization or --project. ``` datumctl mcp [flags] ``` ### Options | Flag | Type | Description | | ---------------- | ------ | --------------------------------------------------------------------- | | `-h`, `--help` | — | Help for mcp. | | `--namespace` | string | Default namespace for CRUD/validation (if YAML or tool args omit it). | | `--organization` | string | Organization ID to target (mutually exclusive with `--project`). | | `--port` | int | Run HTTP debug API on `127.0.0.1:` (MCP still uses STDIO). | | `--project` | string | Project ID to target (mutually exclusive with `--organization`). | ### Options inherited from parent commands | Flag | Type | Description | | ---------------------------- | ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `--as` | string | Username to impersonate for the operation. User could be a regular user or a service account in a namespace. | | `--as-group` | stringArray | Group to impersonate for the operation. Can be repeated to specify multiple groups. | | `--as-uid` | string | UID to impersonate for the operation. | | `--as-user-extra` | stringArray | User extras to impersonate for the operation. Can be repeated to specify multiple values for the same key. | | `--certificate-authority` | string | Path to a cert file for the certificate authority. | | `--disable-compression` | — | If true, opt-out of response compression for all requests to the server. | | `--insecure-skip-tls-verify` | — | If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure. | | `--log-flush-frequency` | duration | Maximum number of seconds between log flushes. (default `5s`) | | `--platform-wide` | — | Access the platform root instead of a project or organization control plane. | | `--request-timeout` | string | The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. `1s`, `2m`, `3h`). A value of zero means don't timeout requests. (default `"0"`) | | `-s`, `--server` | string | The address and port of the Kubernetes API server. | | `--tls-server-name` | string | Server name to use for server certificate validation. If not provided, the hostname used to contact the server is used. | | `--token` | string | Bearer token for authentication to the API server. | | `--user` | string | The name of the kubeconfig user to use. | | `-v`, `--v` | Level | Number for the log level verbosity. | | `--vmodule` | moduleSpec | Comma-separated list of `pattern=N` settings for file-filtered logging (only works for the default text log format). | ### See also * [datumctl](/docs/datumctl/cli-reference/) - A CLI for interacting with the Datum platform ###### Auto generated by spf13/cobra on 24-Feb-2026
