Model model

Model identifier. Accepts the model string, e.g. claude-opus-5-5, or a model_config object for additional configuration control

enum BetaManagedAgentsModel

The model that will power your agent.

See models for additional details and options.

class BetaManagedAgentsModelConfigParams { id; effort; inferenceGeo; speed; }

Optional<String> description

Description of what the agent does.

maxLength2048
Optional<BetaManagedAgentsExecutionIdentityParams> executionIdentity

Execution principal for runs of this agent. Omitting it, sending null, or sending {"type": "service_account"} stores the default.

Optional<List<BetaManagedAgentsUrlMcpServerParams>> mcpServers

MCP servers this agent connects to. Maximum 20. Names must be unique within the array. Every server must be referenced by an mcp_toolset in tools; unreferenced servers are rejected. See the MCP connector guide.

Optional<List<BetaManagedAgentsSkillParams>> skills

Skills available to the agent.

class BetaManagedAgentsAnthropicSkillParams { type; skillId; version; }

An Anthropic-managed skill.

Type type
String skillId

Identifier of the Anthropic skill (e.g., "xlsx").

minLength1
maxLength64
Optional<String> version

Version to pin. Defaults to latest if omitted.

minLength1

class BetaManagedAgentsMcpToolsetParams { type; mcpServerName; configs; defaultConfig; }

Configuration for tools from an MCP server defined in mcp_servers.

class BetaManagedAgentsCustomToolParams { type; description; inputSchema; name; }

A custom tool that is executed by the API client rather than the agent. When the agent calls this tool, an agent.custom_tool_use event is emitted and the session goes idle, waiting for the client to provide the result via a user.custom_tool_result event.
