Struct McpHosts 

pub(crate) struct McpHosts {
    servers: HashMap<String, McpServer>,
    external: HashMap<String, McpServerConfig>,
}

Registry of MCP servers (both in-process SDK and external stdio / SSE / HTTP). Keyed by the name under which the caller registered them via OptionsBuilder::mcp_server / external_mcp_server.

Fields

servers: HashMap<String, McpServer>

external: HashMap<String, McpServerConfig>

Implementations

impl McpHosts

pub(crate) fn new( sdk_entries: Vec<(String, McpServer)>, external: HashMap<String, McpServerConfig>, ) -> Self

Build from the Options.mcp_servers vector of in-process servers plus a HashMap of external configs. Either side may be empty.

pub(crate) fn is_empty(&self) -> bool

True when no servers of either flavour are registered.

pub(crate) fn config_argv(&self) -> String

Build the --mcp-config inline JSON argument. SDK servers emit {"type":"sdk","name":<n>}; external servers serialise via McpServerConfig’s own serde impl. Returns "{"mcpServers":{}}" when empty - caller should skip adding the flag in that case.

pub(crate) async fn dispatch( &self, server_name: &str, req: &JsonRpcRequest, ) -> Dispatched

Route an incoming mcp_message to the named server.
