Struct McpStdioSmokeClient 

pub struct McpStdioSmokeClient { /* private fields */ }

Minimal newline-delimited JSON-RPC MCP client for subprocess smoke tests.

This intentionally exposes raw JSON protocol results so application-level smoke flows can assert the same field names seen by external MCP clients.

Implementations

impl McpStdioSmokeClient

pub fn spawn(command: &mut Command) -> Result<Self, McpStdioSmokeError>

Spawn an MCP stdio server process and connect to its stdin/stdout.

pub fn discover(&mut self) -> Result<Value, McpStdioSmokeError>

Discover the server’s MCP 2026-07-28 capabilities and identity.

pub fn list_tools(&mut self) -> Result<Value, McpStdioSmokeError>

Call tools/list.

pub fn list_resources(&mut self) -> Result<Value, McpStdioSmokeError>

Call resources/list.

pub fn list_resource_templates(&mut self) -> Result<Value, McpStdioSmokeError>

Call resources/templates/list.

pub fn read_resource(&mut self, uri: &str) -> Result<Value, McpStdioSmokeError>

Call resources/read for one concrete URI.

pub fn call_tool( &mut self, name: &str, arguments: Value, ) -> Result<Value, McpStdioSmokeError>

Call tools/call for one tool with JSON object arguments.

pub fn request( &mut self, method: &str, params: Value, ) -> Result<Value, McpStdioSmokeError>

Send a raw JSON-RPC request and return the response result.

pub fn shutdown( &mut self, timeout: Duration, ) -> Result<Option<ExitStatus>, McpStdioSmokeError>

Close stdin, wait briefly for the server, and kill it if it remains alive.

pub fn stderr(&self) -> StderrSnapshot

Return currently captured stderr text.

Trait Implementations

impl Drop for McpStdioSmokeClient

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
