Get one immutable agent version
Returns one immutable agent version by id. The version must belong to the agent in the path; a mismatch is a 404 rather than a cross-agent read.
Authorizations
A Recursion API key, created in the console under API keys.
Headers
Optional tenant consistency check. When present, it must name the tenant bound to the API key, including when x-organization-id is default.
1Organization in which to act. Required for a tenant-scoped API key. Optional for an organization-scoped key, where it must name that same organization. The value may be an organization id or default.
1Path Parameters
Agent id (UUID) the version belongs to.
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 this version belongs to (UUID).
Identifier for this agent version (UUID). Server-assigned. Pass it when starting a session that must run a specific version.
RFC 3339 timestamp of when this record was created. Server-assigned.
Narrows this version's default vaults to individual credentials.
Vaults whose credentials are copied into a new session started from this version when the create request omits vault_ids.
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.
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.
Default inference settings this version applies to every turn unless a session overrides them.
The agent's human-readable label as it stood at this version.
Organization that owns this record. Resolved from the authenticated principal; never accepted from the caller.
Skill packages loaded into the runtime at this version, each an entry with the skill reference and its metadata.
System prompt this version prepends to every conversation.
Monotonically increasing version counter within the agent, starting at 1. Server-assigned.
-9007199254740991 <= x <= 9007199254740991Built-in integrations sessions started from this version may use, each naming an organization connection an admin added. Snapshotted with the version.
User who made the edit that produced this version, for audit. Empty when the version was created by an automated caller.
Billing project copied into sessions started from this version when their create request omits project_id. A non-empty session project_id overrides it.
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.
The agent's free-text note as it stood at this version.
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.
compatible, incompatible Whether sessions created from this version may search and read the session outputs this agent's earlier sessions saved. Omitted means off.
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.
1 <= x <= 10000Free-form caller-supplied key/value labels. Stored verbatim and never interpreted by the service.
Public model id this version runs on, in the same form as an agent's model.
Multi-agent orchestration settings at this version, such as subagent definitions and delegation limits.
Native connections this agent may use, with provider-enforced permission and resource restrictions. Omit or send [] for none. Stored in full on each agent version; secrets remain on the connection.
25Whether this version's agent type supports new sessions here. Other start requirements still apply. Existing sessions and version history remain available when false.
Reviewed template revision this version started from.
Whether sessions created from this version may use the native web_search tool. Omitted on legacy versions and interpreted as enabled.
