Struct McpClient 

pub struct McpClient {
    pub server_info: Option<ServerInfo>,
    /* private fields */
}

MCP protocol client for a single server connection.

Fields

server_info: Option<ServerInfo>

Server info from initialization

Implementations

impl McpClient

pub async fn initialize(&mut self) -> Result<ServerInfo>

Perform the MCP initialization handshake.

Sends initialize request with our client info and protocol version, then sends notifications/initialized to signal readiness.

pub async fn list_tools(&self) -> Result<Vec<McpToolDef>>

Discover all tools available from this server, following nextCursor pagination so a server that pages its tool list isn’t silently truncated to page one. Bounded by a page cap so a server that echoes a stuck cursor can’t loop forever.

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

Call a tool on this server and return the result.

pub async fn shutdown(&self)

Shut down the transport (kills the server process).

pub fn is_shutdown(&self) -> bool

true once Self::shutdown has run. The manager checks this so a call_tool to a stopped-but-still-registered server returns a clean error rather than a broken-pipe transport failure.
