Mastra adds background tasks for agents

Mastra announced background tasks on May 7, 2026, a new configuration option that lets tools run asynchronously so agents can stream progress before, during, and after long-running tool calls. The feature works at the instance, tool, or agent level, requires persistent storage, and supports parallel background tool execution. It is available in `@mastra/core@1.29.0` or later.

// ANALYSIS

This is a solid agent-runtime upgrade: it improves responsiveness without forcing developers to redesign their workflows around blocking tool calls.

–The main value is UX, not just infrastructure: agents can keep talking while work happens in the background.
–The parallel background-tool behavior is especially useful for multi-tool research or orchestration flows.
–The storage requirement matters because this is really about resumable, stateful execution, not just async callbacks.
–Requiring `@mastra/core@1.29.0` or later makes this a versioned platform capability rather than a loose example pattern.

Infisical launches Agent Vault to broker credentials for AI agents without exposing secrets.

On April 22, 2026, Infisical announced Agent Vault, an open-source, research-preview credential security layer for AI agents. The project routes agent traffic through a local forward proxy that injects credentials at the proxy layer, so the agent can call APIs and services without ever reading or logging the underlying secrets. Infisical positions it as an early step toward safer agent deployments across local, sandboxed, on-prem, Kubernetes, and cloud environments.
