agentproto 0.5.0: Credentials, Sandboxes, Honest Costing
agentproto 0.5.0 is an open-source technical release that adds credential brokering, sandboxed agent execution, improved observability, redaction, and honest cost accounting. The release publishes 37 packages (six new) and introduces @agentproto/auth (AIP-50) with multiple credential store backends and a device-code flow engine; @agentproto/sandbox and sandbox-e2b implementing the AIP-36 SandboxProvider lifecycle; and telemetry updates including an OpenTelemetry adapter and Langfuse ingestion. Redaction utilities now scrub secrets by default from telemetry, and usage events carry tokensIn/tokensOut/cost with a four-way source tag that deliberately avoids inventing prices when a model is unpriced. The project remains Apache-2.0 and positions itself as an orchestration/supervision layer for coding agents rather than replacing LLMs.
Open-source technical release adds security (credential broker, sandboxes), observability (OTel, redaction), and honest cost accounting for AI agents — relevant to developer and agent-security workflows but not industry-shifting.

Key Takeaways & Evidence Grounding
- agentproto 0.5.0 release published; 37 packages were released, six of them new.
- @agentproto/auth@0.1.0 implements AIP-50 with three CredentialStore backends (Keychain, Memory, File), an RFC 8628 device-code flow engine, and a CredentialBroker that refreshes tokens and produces ready-to-use headers.
- @agentproto/sandbox@0.1.0 and @agentproto/sandbox-e2b@0.1.0 implement the AIP-36 SandboxProvider interface and enable backend-agnostic sandbox lifecycle (boot/connect/pause/stop).
- @agentproto/telemetry@0.2.0 adds an OpenTelemetry adapter and @agentproto/telemetry-langfuse@0.2.0 ingests session turns into Langfuse traces.
- @agentproto/redaction@0.2.0 provides composable redactors (deny list, value-scan) and the runtime defaults telemetry tracing to the secrets redactor; usage_update events now include tokensIn, tokensOut, and cost with a deliberate 'no-pricing' state when models lack pricing.

agent-stack: Six libs for agent guardrails
Mukunda Katta announces agent-stack, a set of six small, single-concern libraries (AgentFit, AgentGuard, AgentSnap, AgentVet, AgentCast, AgentBudget) that wrap LLM agents (demonstrated on Hermes from Nous Research) to provide operational guardrails such as token-aware context fitting, egress allowlists, snapshot testing of tool-call traces, argument validation, structured-output repair/retry, and per-run budget caps. The libs are published to npm and PyPI, expose thin MCP server variants, are MIT‑licensed, and are available from a GitHub repo with a live Hugging Face demo and a Zenodo paper DOI. The project is v0.1.x and the post lists current limitations (JSON diffs only, pricing overrides, fetch interception caveats, and thin MCP examples). The submission was made for the Hermes Agent Challenge and published on 2026-05-21.
OpenAI Updates Agents SDK with Native Sandboxes
OpenAI updated its Agents SDK to add sandboxing and an in‑distribution harness to help enterprises build safer, more capable agentic applications. The sandbox integration lets agents operate in siloed workspaces with controlled access to files and approved tools, reducing risks from unsupervised execution. The new harness supports deploying and testing agents on frontier models and aims to enable long‑horizon, multi‑step workflows. OpenAI said the harness and sandbox features are launching first in Python, with TypeScript support planned later, and that the capabilities will be available to all customers via the OpenAI API at standard pricing. The company intends to expand the SDK over time with features such as code mode and subagents to help move agents from prototype to production.
AgentKey launches agent credential governance layer
A developer launched AgentKey, an open-source governance layer to stop hardcoding API keys in AI agents. AgentKey enforces zero-access-by-default, lets agents request tool access via APIs, requires human approval in a dashboard, and vends credentials on-demand (rate-limited and logged). Implementation details include per-record AES-256-GCM encryption with fresh IVs, SHA-256-hashed agent keys verified with timing-safe comparisons, and an append-only audit log enforced at the schema level. The stack uses Next.js 16, Drizzle ORM + Neon Postgres, Upstash Redis, Clerk for human auth, and Vercel (including Vercel AI Gateway). The project is BSL 1.1 licensed with automatic conversion to Apache 2.0 on 2030-04-01 and launched on Product Hunt.
