Rename provider auth/MCP contracts to remove the overloaded Runtime suffix so
the shared interfaces read as stable provider capabilities instead of execution
implementation details.
Add a consistent provider-first auth class naming convention by renaming
ClaudeAuthProvider, CodexAuthProvider, CursorAuthProvider, and GeminiAuthProvider
to ClaudeProviderAuth, CodexProviderAuth, CursorProviderAuth, and
GeminiProviderAuth.
This keeps the provider module API easier to scan and aligns auth naming with
the main provider ownership model.
Move provider authentication status logic out of the CLI auth route so auth checks
live with the provider implementations that understand each provider's install
and credential model.
Add provider-specific auth runtime classes for Claude, Codex, Cursor, and Gemini,
and expose them through the shared provider contract as `provider.auth`. Add a
provider auth service that resolves providers through the registry and delegates
status checks via `auth.getStatus()`.
Keep the existing `/api/cli/<provider>/status` endpoints, but make them thin route
adapters over the new provider auth service. This removes duplicated route-local
credential parsing and makes auth status a first-class provider capability beside
MCP and message handling.
Move provider-specific normalizeMessage and fetchHistory logic out of the legacy
server/providers adapters and into the refactored provider classes so callers can
depend on the main provider contract instead of parallel adapter plumbing.
Add a providers service to resolve concrete providers through the registry and
delegate message normalization/history loading from realtime handlers and the
unified messages route. Add shared TypeScript message/history types and normalized
message helpers so provider implementations and callers use the same contract.
Remove the old adapter registry/files now that Claude, Codex, Cursor, and Gemini
implement the required behavior directly.
- Add provider registry to manage LLM providers (Claude, Codex, Cursor, Gemini).
- Create provider routes for MCP server operations (list, upsert, delete, run).
- Implement MCP service for handling server operations and validations.
- Introduce abstract provider class and MCP provider base for shared functionality.
- Add tests for MCP server operations across different providers and scopes.
- Define shared interfaces and types for MCP functionality.
- Implement utility functions for handling JSON config files and API responses.
