Types

StdioTransport

Configuration for stdio transport

pub type StdioTransport {
  StdioTransport
}

Constructors

```
StdioTransport
```

Transport

</>

Transport configuration options supported by the runtime layer.

For now only stdio is supported; HTTP transports expose their own modules under mcp_toolkit/transport and don’t integrate with this abstraction.

pub type Transport {
  Stdio(StdioTransport)
}

Constructors

```
Stdio(StdioTransport)
```

TransportEvent

</>

Events that can occur on a transport

pub type TransportEvent {
  MessageReceived(message: TransportMessage)
  ClientConnected(client_id: String)
  ClientDisconnected(client_id: String)
  TransportError(error: String)
}

Constructors

MessageReceived(message: TransportMessage)

```
ClientConnected(client_id: String)
```
```
ClientDisconnected(client_id: String)
```
```
TransportError(error: String)
```

TransportInterface

</>

Transport interface for sending and receiving messages

pub type TransportInterface {
  TransportInterface(
    send: fn(TransportMessage) -> Result(Nil, String),
    receive: fn() -> Result(TransportEvent, String),
    start: fn() -> Result(process.Subject(TransportEvent), String),
    stop: fn() -> Result(Nil, String),
  )
}

Constructors

TransportInterface(
  send: fn(TransportMessage) -> Result(Nil, String),
  receive: fn() -> Result(TransportEvent, String),
  start: fn() -> Result(process.Subject(TransportEvent), String),
  stop: fn() -> Result(Nil, String),
)

TransportMessage

</>

Message to be sent over any transport

pub type TransportMessage {
  TransportMessage(content: String, id: option.Option(String))
}

Constructors

TransportMessage(content: String, id: option.Option(String))

Values

create_transport

</>

pub fn create_transport(
  transport: Transport,
) -> Result(TransportInterface, String)
