Optional tenant consistency check. When present, it must name the tenant bound to the API key, including when x-organization-id is default.

Path Parameters

agentId
string<uuid>
required

Agent id (UUID) the version belongs to.

agentVersionId
string<uuid>
required

Immutable agent version id (UUID), as listed by managedAgentsListAgentVersions or reported as an agent's latest_agent_version_id.

Response

An immutable snapshot of a standalone Managed Agent's configuration. Sessions reference a version so a running session cannot change under them.

An immutable snapshot of a standalone Managed Agent's configuration. Sessions reference a version so a running session cannot change under them.

agent_id
string
required

Agent this version belongs to (UUID).

agent_version_id
string
required

Identifier for this agent version (UUID). Server-assigned. Pass it when starting a session that must run a specific version.

created_at
string<date-time>
required

RFC 3339 timestamp of when this record was created. Server-assigned.

default_credential_refs
object[] | null
required

Narrows this version's default vaults to individual credentials.

default_vault_ids
string[] | null
required

Vaults whose credentials are copied into a new session started from this version when the create request omits vault_ids.

disabled_integration_mcp_providers
string[] | null
required

Native integration providers whose MCP tools sessions started from this version do not receive. github is ignored, because a GitHub grant always keeps its MCP tools alongside git and gh in the sandbox.

mcp_servers
object[] | null
required

Remote MCP servers attached at this version. Each entry is an object with name and url (http/https); further keys pass to the runtime unchanged. Credentials come from the session's granted vaults.

model_config
object
required

Default inference settings this version applies to every turn unless a session overrides them.

name
string
required

The agent's human-readable label as it stood at this version.

organization_id
string
required

Organization that owns this record. Resolved from the authenticated principal; never accepted from the caller.

skills
object[] | null
required

Skill packages loaded into the runtime at this version, each an entry with the skill reference and its metadata.

system
string
required

System prompt this version prepends to every conversation.

version_number
integer<int64>
required

Monotonically increasing version counter within the agent, starting at 1. Server-assigned.

Required range: -9007199254740991 <= x <= 9007199254740991
built_in_integrations
object[]

Built-in integrations sessions started from this version may use, each naming an organization connection an admin added. Snapshotted with the version.

created_by
string

User who made the edit that produced this version, for audit. Empty when the version was created by an automated caller.

default_project_id
string

Billing project copied into sessions started from this version when their create request omits project_id. A non-empty session project_id overrides it.

default_rubric
string

Markdown rubric that sessions started from this version are graded against by default when they start with a message. A session that supplies its own outcome ignores this entirely.

description
string

The agent's free-text note as it stood at this version.

execution_compatibility
enum<string>

Whether this exact immutable version is compatible with the standalone execution context. Omitted by deployments that do not compute it; a client must treat any present value other than compatible as incompatible.

Available options:
compatible,
incompatible
fileHistoryEnabled
boolean

Whether sessions created from this version may search and read the session outputs this agent's earlier sessions saved. Omitted means off.

max_concurrent_sessions
integer

Maximum concurrent root sessions configured on the agent when this version was minted. Unset means unlimited. Live admission uses the agent head's current value, not this snapshot. Outcome evaluation passes do not take a slot.

Required range: 1 <= x <= 10000
metadata
object

Free-form caller-supplied key/value labels. Stored verbatim and never interpreted by the service.

model
string

Public model id this version runs on, in the same form as an agent's model.

multiagent
object

Multi-agent orchestration settings at this version, such as subagent definitions and delegation limits.

nativeIntegrations

Maximum array length: 25
supports_new_sessions
boolean

Whether this version's agent type supports new sessions here. Other start requirements still apply. Existing sessions and version history remain available when false.

template
object

Reviewed template revision this version started from.

web_search_enabled
boolean
default:true

Whether sessions created from this version may use the native web_search tool. Omitted on legacy versions and interpreted as enabled.
