Abstract transport for MCP communication.

Required Methods

fn send_and_recv<'life0, 'life1, 'async_trait>( &'life0 mut self, request: &'life1 JsonRpcRequest, ) -> Pin<Box<dyn Future<Output = Result<JsonRpcResponse>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Send a JSON-RPC request and receive the response.

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Close the connection.

Provided Methods

fn reset<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Reset per-connection session state so the next operation re-establishes a fresh session. Default is a no-op for stateless transports (stdio).

fn health_check(&mut self) -> bool

Check whether the underlying transport is still alive without sending a real request. The HTTP and SSE transports always return Ok(true) — connection drops surface through send_and_recv errors. The stdio transport verifies the child process is still running via try_wait().
