pub async fn connect_with_gen( provider: &Provider, keyring: &Keyring, gen_ctx: Option<&GenContext>, auth_cache: Option<&AuthCache>, ) -> Result<Self, McpError>

Connect to an MCP server, optionally using a dynamic auth generator.

pub async fn list_tools(&self) -> Result<Vec<McpToolDef>, McpError>

Discover tools via tools/list. Results are cached.

pub async fn call_tool( &self, name: &str, arguments: HashMap<String, Value>, ) -> Result<McpToolResult, McpError>

Execute a tool via tools/call.

pub async fn disconnect(&self)

Disconnect from the MCP server.

pub async fn invalidate_cache(&self)

Invalidate cached tools (e.g., after tools/list_changed notification).
