Struct McpServer 

pub struct McpServer {
    name: String,
    version: String,
    instructions: Option<String>,
    tools: BTreeMap<String, Arc<dyn Tool>>,
}

A fully-constructed MCP server. Clone is cheap (just bumps Arcs).

Fields

name: String

version: String

instructions: Option<String>

tools: BTreeMap<String, Arc<dyn Tool>>

Implementations

impl McpServer

pub fn has_tool_prefix(&self, prefix: &str) -> bool

Whether any registered tool’s name starts with prefix, so a host can introspect which tool group it registered.

pub fn tool_names(&self) -> Vec<&str>

The names this server carries, in the order tools/list answers them, so a host can record the surface it hands a child.

pub fn tool_schemas(&self) -> Vec<(String, Value)>

Every registered tool’s name and input schema, so a test can pin the surface a family advertises. Test-only.

pub async fn dispatch(&self, req: &JsonRpcRequest) -> Option<JsonRpcResponse>

Dispatch one JSON-RPC request to the appropriate handler.

Returns None for JSON-RPC notifications (no id) - notifications must not elicit a response per the spec. Returns Some(response) for every id-bearing request, success or error.

This method is pure (modulo tool side-effects): no I/O, no timeouts, no mutation of self. Thread-safe; cheap to call concurrently.

async fn call_tool( &self, params: Option<&Value>, ) -> Result<ToolOutput, McpError>
