# What endpoint is used to create a server token?

> Technical breakdown of the POST requirements mapping explicit authentication credentials back to MCP architectures.

# The Server Token Creation Endpoint

For engineers automating the deployment of new AI agent infrastructure, generating deterministic authentication boundaries dynamically relies heavily on the token instantiation endpoint.

## The API Endpoint

**`POST /servers/{serverId}/tokens`**

The target orchestration node is inferred inherently from the `{serverId}` deployed directly into the network HTTP request path.

### Request Body Formatting

Using the mapped [`CreateServerTokenRequest`](/api-reference/servers/tokens/create-mcp-server-token) structure, submit a JSON object housing a `token` map mapping the constraints explicitly to `ServerTokenCreate`.

```json theme={null}
{
 "token": {
 "name": "pipelineDeployKey",
 "expiresAt": "2027-01-01T00:00:00Z"
 }
}
```

* **`name`** *(string)*: A mandatory human-readable identifier. Useful when listing and auditing long-term credentials later to determine deprecation readiness.
* **`expiresAt`** *(string, optional)*: An ISO 8601 formatted datetime layout dictating when the credential inherently self-destructs. If omitted entirely, the credential maintains active perpetuity natively.

### Important: Handling the Response

The `201 Created` return delivers the [`CreateServerTokenResponse`](/api-reference/servers/tokens/create-mcp-server-token) mapping object explicitly containing the newly generated schema.

```json theme={null}
{
 "token": {
 "id": "tQ9pV1mN8xK",
 "serverID": "sE8vKd2qLp9",
 "name": "pipelineDeployKey",
 "expiresAt": "2027-01-01T00:00:00Z",
 "createdAt": "2026-02-24T00:00:00Z",
 "value": "mcp_rt_81K..." 
 }
}
```

Crucially, the `value` property contains the raw, globally unique cryptography string your downstream pipelines need to communicate natively with HasMCP. You must cache/inject this intelligently.
