Good morning. It's Sunday, March 15th, 2026. Here's your agent platform briefing — three new developments worth your attention this morning.

**OpenClaw 2026.3.13 — Live Chrome Attachment and Browser Automation Overhaul** — OpenClaw released version 2026.3.13 on March 14th, with the headline feature being live Chrome session attachment. Agents can now connect to and control your existing Chrome browser session in real time, rather than spinning up a separate isolated browser. On the automation side, the browser/act system gained batched actions, selector targeting, and delayed click support with normalized batch dispatch — making multi-step web workflows significantly more reliable. The update also brings a Docker timezone override (via OPENCLAW_TZ) and a redesigned mobile interface. No CVEs or security fixes are listed in this release. Worth updating when you get a chance — it's been a few versions since GLaDOS synced up.

**Anthropic Drops the Long-Context Premium — 1M Token Window Now GA at Standard Pricing** — Anthropic quietly made a significant pricing move on March 13th: the full one-million-token context window is now generally available for Claude Opus 4.6 and Sonnet 4.6 at standard API pricing, with no surcharge. Opus 4.6 stays at five dollars per million input tokens and twenty-five dollars output. Previously, long-context usage carried additional costs or was rate-limited. This is a meaningful change for agentic workflows that need to ingest large codebases, long documents, or extended conversation histories. Anthropic also announced a two-week promotion starting March 14th that doubles usage limits during off-peak hours — a small gesture to users following the Pentagon saga brand momentum.

**MCP CVE-2026-31841 — Hyperterse Search Tool Leaks Raw SQL to Clients** — A medium-severity vulnerability was published this week for Hyperterse, an MCP server implementation. Versions 2.0.0 and later expose raw SQL database statements to MCP clients through the search tool — the tool fails to sanitize internal query representations before returning results. This means any AI agent connected to a Hyperterse MCP server could read the underlying database queries, potentially revealing schema structure, table names, and query logic that should be opaque. It's a good reminder that MCP server security is still maturing — if you're running any MCP servers that touch databases, audit what they return to clients. Patch details are available via GitLab advisories.

That's the briefing for Sunday, March 15th. NVIDIA GTC 2026 kicks off tomorrow with Jensen Huang's keynote at 11 AM Pacific — expect major chip announcements. We'll cover that in tomorrow's briefing.
