Struct McpPluginFactory 

pub struct McpPluginFactory { /* private fields */ }

Plugin factory for MCP. Add once to LashCoreBuilder via .plugin(Arc::new(factory)).

Implementations

impl McpPluginFactory

pub async fn new( servers: BTreeMap<String, McpServerConfig>, ) -> Result<Self, McpError>

Connect to every configured server eagerly and return a factory whose pool is ready to use. The pool is Arc-shared across sessions; cloning the factory and adding it to multiple LashCores shares the same connections.

pub fn empty() -> Self

Empty pool — useful when servers are added at runtime via McpPluginFactory::attach_server.

pub fn pool(&self) -> &Arc<McpConnectionPool>

Direct access to the underlying pool, in case the embedder wants to inspect or mutate it directly.

pub async fn attach_server( &self, server_name: String, config: McpServerConfig, ) -> Result<(), McpError>

Attach a new server at runtime. The new tools become visible to any session created after this call returns; existing sessions will see the new tools after their next tool-surface refresh.

pub async fn detach_server(&self, server_name: &str) -> Result<(), McpError>

Detach a server at runtime.

Trait Implementations

impl PluginFactory for McpPluginFactory

fn id(&self) -> &'static str

fn build( &self, _ctx: &PluginSessionContext, ) -> Result<Arc<dyn SessionPlugin>, PluginError>

Produce a session-scoped plugin. Must be cheap — see the trait-level docs for the full contract.

fn lashlang_abilities(&self) -> LashlangAbilities

fn lashlang_language_features(&self) -> LashlangLanguageFeatures

fn lashlang_resources(&self) -> ResourceCatalog

Host-owned Lashlang catalog entries that code may link against.
