CopilotKit

Public API inventory

Supported entry points and API families for @copilotkit/angular.

The supported entry points are @copilotkit/angular, @copilotkit/angular/mcp-apps, and @copilotkit/angular/styles.css. The published package includes API.md, an alphabetized, machine-validated list of every exported value and type. A test resolves both TypeScript entry points and requires every export to appear exactly once in that inventory.

Root API families

  • Setup and runtime: provideCopilotKit, CopilotKit, CopilotKitConfig, configuration and label providers, and injection tokens.
  • Complete UI: CopilotChat, CopilotPopup, CopilotSidebar, CopilotThreadsDrawer, and their input/model types.
  • Composable chat UI: CopilotChatView, message, input, textarea, suggestion, toolbar, button, attachment, audio, scroll, cursor, disclaimer, feather, tools-menu, and renderer components plus their slot/context types.
  • Agents and application state: injectAgentStore, AgentStore, connectAgentContext, CopilotKitAgentContext, injectChatState, injectThreads, injectMemories, and their stores, controllers, and types.
  • Tools and activities: registerFrontendTool, registerRenderToolCall, registerHumanInTheLoop, registerRenderActivityMessage, RenderToolCalls, CopilotDefaultToolRenderer, schemas, configurations, renderer interfaces, and safe parsing/serialization utilities.
  • Interrupts: injectInterrupt, InterruptController, InterruptExpiredError, and the event, view, runner, handler, and options types.
  • Generative UI: A2UI configuration, activity/tool/progress/recovery components and lifecycle schemas; Open Generative UI configuration, sandboxes, activity/tool renderers, content schemas, and constants.
  • Attachments and transcription: attachment types, queue and renderer components, attachment directive, audio recorder controls, transcription function, errors, and result/state types.
  • Slots, directives, and utilities: slot registry and render helpers, stick-to-bottom, tooltip, resize/scroll services and state, class-name and tool-call utilities.
  • Protocol types: selected AG-UI messages and CopilotKit suggestion and memory types are re-exported so application signatures use the same types as the SDK.

The exported ɵCOPILOTKIT_BUILT_IN_ACTIVITY_RENDERERS token is explicitly internal. It exists only for CopilotKit-maintained secondary entry points and applications must not depend on it.

MCP Apps API family

The secondary entry point exports provideMCPApps, its configuration and DI tokens, the snapshot schema and type, the ready-made activity renderer config, and CopilotMCPAppsActivityRenderer/CopilotMCPAppsWidget for advanced hosts.

Use the task-specific reference pages for signatures and behavior. Consult the API.md included beside the package README when reviewing the exact symbol inventory for an installed version; that file is the normative export list.
