Struct McpToolExecutor 

pub struct McpToolExecutor { /* private fields */ }

MCP tool executor – routes tool calls to the appropriate MCP server.

Implementations

impl McpToolExecutor

pub fn new() -> Self

pub fn with_fallback(self, fallback: Arc<dyn ToolExecutor>) -> Self

pub async fn add_server(&self, server: McpServer) -> Result<Vec<String>, String>

Add an MCP server and discover its tools. Returns the list of discovered tool names (canonical form: mcp_{server}_{tool}).

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

Get tool schemas from all connected MCP servers.

pub async fn shutdown_all(&self)

Shut down all MCP servers.

Trait Implementations

impl Default for McpToolExecutor

fn default() -> Self

Returns the “default value” for a type.

impl ToolExecutor for McpToolExecutor

fn execute<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, tool: &'life1 str, params: &'life2 Value, ) -> Pin<Box<dyn Future<Output = Result<Value, String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

fn execute_with_action<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, tool: &'life1 str, params: &'life2 Value, action_id: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<Value, String>> + Send + 'async_trait>>

Variant that also carries the originating proposal Action.id. WS-based executors (car-server-core::WsToolExecutor) use it so the daemon-initiated tools.execute request to the client carries the same id the host’s process-wide handler is keyed on — without this round-trip the host can’t disambiguate concurrent callbacks for the same tool (Parslee-ai/car-releases#43 follow-up). In-process executors that don’t need it can keep the default forward to [execute].
