Struct Server 

pub struct Server {
    pub name: String,
    pub url: String,
    pub initialize_result: InitializeResult,
    pub laboratory: Option<Laboratory>,
    pub laboratory_id: Option<String>,
    pub plugin: Option<Plugin>,
}

One connected upstream MCP server.

Fields

name: String

The proxy’s routing prefix for this server (matches the <prefix>_ prepended to its tools/resources in the aggregated surface).

url: String

The upstream server’s URL.

initialize_result: InitializeResult

The server’s initialize response: capabilities, server_info (name, version, title, description), instructions, protocol version.

laboratory: Option<Laboratory>

Set only when this upstream is genuinely a laboratory — i.e. a client (websocket) laboratory today. Non-laboratory servers (plain HTTP, the primary objectiveai MCP, plugins) leave this None.

laboratory_id: Option<String>

The laboratory’s ASSISTANT-FACING composite id — {machineID}/{base62(state)}/{base62(laboratoryID)} (ClientLaboratory::composite_id), what laboratory_transfer takes as source/destination. Present exactly when laboratory is (and its marker carries the machine pair).

plugin: Option<Plugin>

Set only when this upstream is a plugin-hosted MCP server. Other servers (plain HTTP, the primary objectiveai MCP, laboratories) leave this None.

Trait Implementations

impl Clone for Server

fn clone(&self) -> Server

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Server

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Server

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Server

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for Server

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
