20 open-source Jev combos you can plug into real products
A list of ways to wire Jev's Choice, Score and Noul decision layer into open-source projects including LangGraph, MCP SDK, Temporal, Qdrant and Meilisearch.
this is pure treasure: 20 open-source JEV combos you can plug into real products. JEV gives you 3 primitives: Choice, Score and Noul. it makes the judgment, code enforces the rules, and another tool executes the work. ROUTE THE WORK 1. JEV × Hermes Agent route decisions into autonomous agent workflows. https://github.com/NousResearch/hermes-agent 2. JEV × LangGraph use JEV as a decision layer inside graph-based agent flows. https://github.com/langchain-ai/langgraph 3. JEV × MCP SDK let JEV decide which tool or action should run next. https://github.com/modelcontextprotocol/typescript-sdk 4. JEV × Temporal use JEV decisions inside durable workflows. https://github.com/temporalio/sdk-typescript 5. JEV × E2B combine narrow decisions with sandboxed code execution. https://github.com/e2b-dev/E2B FIND THE EVIDENCE 6. JEV × Meilisearch retrieve relevant context before making a decision. https://github.com/meilisearch/meilisearch 7. JEV × Qdrant score decisions against vector-retrieved evidence. https://github.com/qdrant/qdrant 8. JEV × Docling turn documents into structured context for JEV. https://github.com/docling-project/docling 9. JEV × Graphiti use graph memory to give JEV better context. https://github.com/getzep/graphiti 10. JEV × LlamaIndex connect retrieval pipelines directly to the decision layer. https://github.com/run-llama/llama_index VERIFY THE RESULT 11. JEV × Langfuse trace and inspect decisions in production. https://github.com/langfuse/langfuse 12. JEV × Promptfoo test JEV decisions against evals and failure cases. https://github.com/promptfoo/promptfoo 13. JEV × Semgrep judge findings, then let code enforce security rules. https://github.com/semgrep/semgrep 14. JEV × Sentry route errors into the right recovery path. https://github.com/getsentry/sentry 15. JEV × Playwright verify browser actions before moving to the next step. https://github.com/microsoft/playwright OPERATE THE PRODUCT 16. JEV × GitHub MCP decide when to inspect repos, issues or code changes. https://github.com/github/github-mcp-server 17. JEV × PostHog use product data to score what should happen next. https://github.com/PostHog/posthog 18. JEV × Resend decide when and what email action should run. https://github.com/resend/resend-node 19. JEV × Stripe put a decision layer in front of payment workflows. https://github.com/stripe/stripe-node 20. JEV × Cloudflare Workers AI run lightweight decision flows close to the edge. https://github.com/cloudflare/workers-sdk the loop: collect state → ask JEV a precise Choice, Score or Noul question → check confidence and policy in code → execute or escalate to a human → log the result. these are architecture ideas, not official integrations. save this and build a second brain for your product.
