# Angular public API

This file is the exhaustive public-export contract for `@copilotkit/angular`.
Every symbol listed below is supported for application use unless it appears
under **Internal extension points**. Removing or incompatibly changing a public
symbol requires the package's normal breaking-change process.

For task-oriented examples, start with the [package README](./README.md) and the
[Angular documentation](https://docs.copilotkit.ai/frontends/angular). The high-level
APIs most applications need are `provideCopilotKit`, `CopilotChat`,
`CopilotPopup`, `CopilotSidebar`, `injectAgentStore`, `injectCapabilities`, the
`register*` helpers, and the `inject*` controllers. The remaining components
and context types are supported customization primitives for replacing
individual chat slots.

## Root entry point

### Internal extension points

The following exported Angular DI tokens exist only so CopilotKit-maintained
code can hook Inspector development mode and built-in renderers. Applications
must not depend on them; the `ɵ` prefix and TSDoc mark them internal.

- `ɵCOPILOTKIT_BUILT_IN_ACTIVITY_RENDERERS`
- `ɵCOPILOTKIT_INSPECTOR_DEVELOPMENT_MODE`
<!-- public-api:root:end -->

## MCP Apps entry point

Import these opt-in symbols from `@copilotkit/angular/mcp-apps`. This secondary
entry point keeps the MCP Apps sandbox and protocol code out of applications
that do not enable it. Prefer `provideMCPApps`; the remaining exports support
custom hosts, renderers, and protocol testing.

<!-- public-api:mcp-apps:start -->

- `CopilotMCPAppsActivityRenderer`
- `CopilotMCPAppsWidget`
- `DEFAULT_MCP_APPS_CONFIG`
- `MCPAppsConfig`
- `MCPAppsHostInfo`
- `MCPAppsSnapshotContent`
- `MCP_APPS_CONFIG`
- `mcpAppsActivityRendererConfig`
- `mcpAppsSnapshotContentSchema`
- `provideMCPApps`
<!-- public-api:mcp-apps:end -->

The MCP Apps renderer uses the same inline `srcdoc` proxy, sandbox permissions,
and resource-domain CSP as the React SDK.
