MongoHive
Built at The Harness Engineering & Model Wrangling Hackathon · Sep 26, 2026 · New York, NY

MongoHive turns what one agent learns into tested tools every teammate's agent can call by name. When your Claude or Codex agent finishes an investigation, a background worker distills it into a reusable, read-only tool persisted in MongoDB Atlas. A teammate's background worker checks it independently, and disagreements go to a human. Promoted tools then appear as named MCP tools in everyone's agent. Versions, evals and promotion live in Atlas, and change streams push updates into each agent's chat.
