Real Cursor IDE now uses AgentService at agent.api5.cursor.sh (HTTP/2-only) while 9router still spoke the retired ChatService at api2.cursor.sh with outdated headers, producing HTTP 429 "Update Required". Add an executeAgent path that builds an agent.v1.RunRequest Connect RPC over a raw http2 stream and fetches the account-specific usable model catalog via GetUsableModels. Also implement MCP tool calling over AgentService: encode OpenAI tools as AgentRunRequest.mcp_tools (McpToolDefinition with google.protobuf.Value input_schema), decode McpArgs tool calls, and forward them to the client as OpenAI tool_calls so the client runs the tool and resumes in the next turn. Reply to request_context_args with a non-empty RequestContext, to server heartbeats with client_heartbeat, and to KV blob get/set with empty results, so action queries no longer stall the stream. Fold the client system prompt into the user message (custom_system_prompt makes the server return an empty turn). Bump clientVersion to 3.12.17 and add the x-cursor-client-commit header so the gateway identifies as a current Cursor IDE release.
9Router Embeddings Tests
Unit tests for the /v1/embeddings endpoint implementation.
Setup
Vitest must be installed globally or in /tmp/node_modules (due to npm workspace hoisting from the root Next.js project):
cd /tmp && npm install vitest
Running Tests
cd tests/
NODE_PATH=/tmp/node_modules /tmp/node_modules/.bin/vitest run --reporter=verbose --config ./vitest.config.js
Or using the package script (from the tests/ directory):
npm test

embeddings.cloud.test.js (23 tests)
- CORS OPTIONS: 200 response, empty body, correct headers
- Authentication: missing key, bad format, old-format key, wrong key value, valid key
- Body validation: invalid JSON, missing model, missing input, bad model
- Happy path: single string, array, correct delegation, CORS header, machineId override
- Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
- Error propagation: non-fallback errors passed through, 429 exhausts accounts
- machineId override: validates key, rejects wrong key
