The value is a Workspace ID (for example, `wrkspc_011CZkZaBF1tNoB5wlCeusgy`). Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace. ## Returns - `class BetaManagedAgentsCredentialValidation` Result of live-probing a credential against its configured MCP server. - `type: Literal["vault_credential_validation"]` - `credential_id: str` Unique identifier of the credential that was validated. - `has_refresh_token: bool` Whether the credential has a refresh token configured. - `mcp_probe: Optional[BetaManagedAgentsMCPProbe]` Details of the failing MCP probe step. Null when the probe succeeded. - `http_response: Optional[BetaManagedAgentsRefreshHTTPResponse]` The captured HTTP error response. Null when no HTTP response was received (timeout, DNS, TLS). - `body: str` Response body. May be truncated and has sensitive values scrubbed. - `body_truncated: bool` Whether `body` was truncated. - `content_type: str` Value of the `Content-Type` response header. - `status_code: int` HTTP status code. format: int32 - `method: str` The MCP method that failed (for example `initialize` or `tools/list`). - `refresh: Optional[BetaManagedAgentsRefreshObject]` Details of the refresh-token exchange attempted on a 401. Null when no refresh was attempted. - `http_response: Optional[BetaManagedAgentsRefreshHTTPResponse]` The captured HTTP error response from the token endpoint. Populated only when `status` is `failed`. - `status: Literal["succeeded", "failed", "connect_error", "no_refresh_token"]` Outcome of the refresh attempt. - `"succeeded"` The token endpoint returned a new access token. - `"failed"` The token endpoint returned an error response. See `http_response` for detail. - `"connect_error"` The token endpoint could not be reached (DNS, TLS, or connection error). - `"no_refresh_token"` No refresh token is stored for the credential, so no exchange was attempted. - `status: BetaManagedAgentsCredentialValidationStatus` Overall verdict of the validation probe. - `"valid"` The credential successfully authenticated against its MCP server. - `"invalid"` The probe reached the MCP server and was rejected, and a refresh (if attempted) did not recover it. - `"unknown"` The probe could not determine validity — for example, a transport error or a successful refresh that was not re-probed. - `validated_at: datetime` When the validation probe was performed. format: date-time - `vault_id: str` Identifier of the vault containing the credential. ## Example ```python import os from anthropic import Anthropic client = Anthropic( api_key=os.environ.get( "ANTHROPIC_API_KEY" ), # This is the default and can be omitted ) beta_managed_agents_credential_validation = ( client.beta.vaults.credentials.mcp_oauth_validate( credential_id="vcrd_011CZkZEMt8gZan2iYPQfSkw", vault_id="vlt_011CZkZDLs7fYzm1hXNPeRjv", ) ) print(beta_managed_agents_credential_validation.credential_id) ``` ### Response (200) ```json { "credential_id": "vcrd_011CZkZEMt8gZan2iYPQfSkw", "has_refresh_token": true, "mcp_probe": { "http_response": { "body": "body", "body_truncated": true, "content_type": "content_type", "status_code": 0 }, "method": "method" }, "refresh": { "http_response": { "body": "body", "body_truncated": true, "content_type": "content_type", "status_code": 0 }, "status": "succeeded" }, "status": "valid", "type": "vault_credential_validation", "validated_at": "2026-03-15T10:00:00Z", "vault_id": "vlt_011CZkZDLs7fYzm1hXNPeRjv" } ```
