Builder After Hours: Durable Agents with MongoDB, Temporal & Keycard

​Join MongoDB, Temporal, and Keycard for a developer-focused evening exploring the infrastructure beneath reliable AI agents. We'll trace a source-data change through durable ingestion, embedding, MongoDB Atlas Vector Search, and a deep-agent research experience, then unpack how the system survives failures without repeating completed work.

​See an end-to-end demonstration of the joint reference architecture, followed by technical deep dives into:

​Temporal — Durable workflows, automatic retries, checkpointing, resumability, parallel execution, and auditable multi-step agent orchestration.

​MongoDB — Content-change tracking, Voyage AI embeddings and reranking, Atlas Vector Search, operational data and application state, and zero-downtime embedding-model migrations.

​Keycard — Per-agent identity and runtime authorization, short-lived task-scoped credentials minted inside activities, agents acting as themselves or on behalf of a user, tokens kept out of workflow history, and a full audit trail of every delegation chain.

​You'll leave with an open reference implementation and a practical mental model for building production RAG pipelines and agent workflows that stay current, recover cleanly, and scale beyond a fragile demo.

​About MongoDB
MongoDB is a developer data platform for building modern applications. MongoDB Atlas unifies operational data, vector search, and application state so AI systems can retrieve fresh context and act on it in real time.

​About Temporal
Temporal is a durable execution platform for crash-proof code. Whether it's an AI agent or a bank money transfer, your application is guaranteed to execute to completion in the face of failure.

​About Keycard

​Keycard is runtime authorization infrastructure for AI agents. Keycard replaces static secrets with per-agent identities and task-scoped, short-lived credentials, so an agent can only do the thing it was asked to do.
