Struct McpServer 

pub struct McpServer { /* private fields */ }

Serves an application’s tools to an external AI client.

Transport-agnostic: it turns a request into a response and nothing more, so the same server works over stdio, over a local HTTP endpoint, or over an in-memory pipe in a test.

Implementations

impl McpServer

pub fn new(name: impl Into<String>, version: impl Into<String>) -> Self

pub fn with_permissions(self, permissions: AiPermissions) -> Self

What an external AI is allowed to do. Nothing, unless the product says so.

pub fn with_confirmation( self, confirmation: Arc<dyn ConfirmationService>, ) -> Self

Ask a human before a mutating tool takes effect.

Without this, Commit and Delete tools are refused at the boundary — the safest default. A product that grants mutation must wire a confirmer (a native dialog, a policy file) at composition time.

pub fn session_id(&self) -> &str

The id this session is logged under.

pub fn with_tool(self, tool: Arc<dyn Tool>) -> Self

pub async fn handle(&self, request: Request) -> Option<Response>

Handle one request. Returns None for a notification.

pub async fn handle_line(&self, line: &str) -> Option<Response>

Parse and handle one line of JSON. Convenience for line-based transports.
