How Tavily Uses MongoDB to Enhance Agentic Workflows

Right, so "preventing hallucinations and giving agents up-to-date context is more important than ever." You don't say? Because for a second there, I thought we were all just aiming for more creative fiction and stale data. Glad someone finally cracked that code, after... checks notes... every single other LLM company has said the exact same thing for the past two years. But sure, this time it's different.

It all starts with Tavily, a "simple but powerful idea" that "exploded" with 20,000 GitHub stars. Oh, that's the metric we're using for production readiness now? Not, you know, SLA compliance or incident reports that aren't longer than a novel? I’ve seen "viral success" projects crumble faster than my will to live on a Monday morning when the "simple" solution starts hemorrhaging memory. And now, suddenly, "developers are slowly realizing not everything is semantic, and that vector search alone cannot be the only solution for RAG." Gasp! It's almost like a single-tool solution isn't a panacea! Who could have predicted that? Oh, right, anyone who's ever deployed anything to production.

Then, the true revelation: the "new internet graph" where "AI agents act as new nodes." Because apparently, the old internet, the one where humans gasp searched for things and got answers, just wasn't cutting it. Now, agents "don't need fancy UIs." They just need a "quick, scalable system to give them answers in real time." So, a search engine, but for robots, built on the premise that robots have different needs than people. Riveting. And they're "sticking to the infrastructure layer" because "you don't know where the industry is going." Translation: We're building something that sounds foundational so we can pivot when this current hype cycle inevitably collapses.

And then the plot twist, the foundation for this marvel: MongoDB. Oh, Rotem, you "fell in love with MongoDB"? "It's amazing how flexible it is–it's so easy to implement everything!" Bless your heart, sweet summer child. That's what they all say at the beginning. It's always "flexible," "fast," "scales quickly" – right up until 3 AM when your "almost like it's in memory" hot cache decides to become a "cold, dead cache" that's taken your entire cluster down. And the "document model"? That's just code for "we don't need schemas, let's YOLO our data until we need to migrate it, then realize we have 17 different versions of the same field and it's all NullPointerException city, and half the records are corrupted because someone forgot to add {"new_field": null} to a million existing documents." My PTSD from that last "simple" migration is flaring up just thinking about it.

They trot out the "three pillars of success," naturally:

And the trust! Oh, the trust! "You want to make sure that you're choosing companies you trust to handle things correctly and fast." And if I have feedback, "they will listen." Yes, they'll listen right up until you cancel your enterprise support contract.

So, the "multi-agent future," where we'll be "combining these one, two, three, four agents into a workflow." More complexity, more points of failure, more fun for on-call. The internet welcomed people, now AI agents join the network, and companies like Tavily are "building the infrastructure to ensure this next chapter of digital evolution is both powerful and accessible." And I’ll be the one building the rollback plan when it inevitably collapses. My money's on the first major outage involving a rogue AI agent accidentally recursively querying itself into a distributed denial of service attack on Tavily's own "internet graph." And I'll be here, clutching my pillow, because I've seen this movie before. It always ends with me, a VPN connection, and a database dump, wishing I'd just stuck with a spreadsheet.
