Remove legacy backend routes that no longer have frontend or internal
callers, including the old Claude/Codex MCP APIs, unused Cursor and Codex
helper endpoints, stale TaskMaster detection/next/initialize routes,
and unused command/project helpers.
This reduces duplicated MCP behavior now handled by the provider-based
MCP API, shrinks the exposed backend surface, and removes probe/service
code that only existed for deleted endpoints.
Add an MCP settings API audit document to capture the route-usage
analysis and explain why the legacy MCP endpoints were considered safe
to remove.
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.
- 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.
