Cherry-pick from codex/omniroute-fixes-20260324:
- Replace MCP singleton transport with per-session architecture for Streamable HTTP
- Fix Claude passthrough via OpenAI round-trip normalization
- Add detectFormatFromEndpoint() for endpoint-aware format detection
- Support raw code#state in OAuth modal for Claude Code remote auth
- Expose cloudConfigured/cloudUrl/machineId in settings API
- Switch docker-compose.prod.yml target to runner-cli
- Add 3 new tests for round-trip and detectFormat
PR: #562
- Add .catch() to initial and periodic sync promises (Gemini, Kilo)
- Wrap JSON.parse in try-catch for corrupted DB data (Kilo)
- Wrap response.json() in try-catch for invalid LiteLLM JSON (Kilo)
- Validate PRICING_SYNC_INTERVAL (guard against NaN/0 → tight loop) (Copilot)
- Validate and allowlist sources — reject unknown, prevent empty sync
from clearing pricing_synced data (Copilot, Kilo)
- Extract merge loop into shared iteration to reduce duplication (Gemini)
- Add data/warnings fields to MCP output schema (Copilot)
- Remove unused z import in vitest (Copilot)
- Filter non-string entries from sources array in API route (Copilot)
- Track active interval for accurate getSyncStatus().nextSync (Copilot)
- Created httpTransport.ts with singleton MCP server and WebStandard
Streamable HTTP transport running inside Next.js process
- Added /api/mcp/sse route (GET+POST) for SSE transport
- Added /api/mcp/stream route (GET+POST+DELETE) for Streamable HTTP
- Added mcpTransport enum to settingsSchemas (stdio|sse|streamable-http)
- Updated /api/mcp/status to report HTTP transport state
- Added TransportSelector UI with mode buttons and connection URL display
- Routes guard against disabled MCP or wrong transport mode
- Add type annotations to all providerModels helper functions
- Introduce LegacyProvider interface in providerRegistry
- Refactor translator system to use self-registering module pattern
with bootstrapTranslatorRegistry() and per-file imports
- Simplify translator/index.ts by delegating to modular translators
- Remove hardcoded Gemini OAuth client secret for security
Introduce `normalizeQuotaResponse` and `normalizeCombosResponse` helpers
to handle varying API response shapes (array vs wrapped object)
consistently across MCP server and advanced tools. Add optional `meta`
field to checkQuotaOutput schema and update sourceEndpoints to reflect
current API routes.
- Add unit tests for 8 MCP advanced tool handlers (Phase 3)
- Migrate test files from JavaScript to TypeScript (.ts/.tsx)
- Restructure file paths from app/ to src/app/ across all tests
- Refactor route assertions into reusable assertRouteMethods helper
- Add tests for new API routes (compliance, audit-log, evals/[suiteId])
- Update barrel export tests to use consolidated assertion pattern
Register 8 new advanced MCP tools (simulate_route, set_budget_guard,
set_resilience_profile, test_combo, get_provider_metrics,
best_combo_for_task, explain_route, get_session_snapshot) with their
handler implementations. Add A2A smart routing skill that routes
prompts through the OmniRoute pipeline with routing explanation,
cost envelope, and resilience trace metadata.
Add stdio-based MCP server support to OmniRoute CLI, enabling AI agents
in VS Code, Cursor, Claude Desktop, and Copilot to interact with
OmniRoute tools (health, combos, quota, routing). Update help text,
gitignore vscode-extension subproject, and include MCP/A2A strategy report.
