OpenCode Ships Browse: MCP Server + Chromium Extension Lets Coding Agents Drive Your Signed-In Real Browser

On 2026-11-07 the official OpenCode account announced Browse: an MCP server plus Chromium extension that lets agents drive your local real browser with existing tabs, logins, and extensions. Sensitive steps such as login, 2FA, or payment hand the tab back until you click Continue. It works with Chrome, Edge, Brave, Arc and other Chromium browsers, and with MCP clients including OpenCode, Claude Code, Cursor, Codex, and Zed. Source is MIT at anomalyco/browse; the npm package is @opencode/browse.

OpenCode Ships Browse: MCP Server + Chromium Extension Lets Coding Agents Drive Your Signed-In Real Browser

Key Takeaways

  • Shape: MCP server + Chromium extension; agents drive Playwright tabs in collapsed background groups, with screenshots, recordings, and HAR capture
  • Compatibility: browsers include Chrome, Edge, Brave, Arc, Helium, Vivaldi, Opera, Chromium; MCP clients include OpenCode, Claude Code, Cursor, Codex, Zed, and more
  • Safety UX: login, 2FA, and payment steps can hand off to the user; sessions support site allowlists; OpenCode published no standalone benchmark
  • Install: prefer the Chrome Web Store extension, or npx @opencode/browse install / curl -fsSL https://opencode.ai/browse/install | bash (Node.js 22.19+)
  • Source: as of write time the official post had about 3,305 likes, 190 reposts, and ~135K impressions; GitHub anomalyco/browse had about 108 stars (MIT)

OpenCode team ships Hex 3.0 stable: local voice dictation for Mac, Windows and Linux, built for talking to coding agents

Anomaly, the company behind open-source coding agent OpenCode, shipped Hex 3.0 stable: hold a shortcut, speak, and the text is pasted at your cursor. Recognition runs on-device, local model memory drops from about 900 MB to about 160 MB, and it adds vocabulary hints, a hex CLI and optional OpenCode rewriting.

OpenCode team ships Hex 3.0 stable: local voice dictation for Mac, Windows and Linux, built for talking to coding agents

Key Takeaways

  • Hex v3.0.0 was released on GitHub at 00:38 UTC on Oct 31; it is MIT-licensed, written in Rust, and the repo has about 1,557 stars (release notes)
  • Vendor figures: local model memory drops from about 900 MB to about 160 MB; since 2.3.0 it streams, so a 2-minute dictation finishes about 0.1 s after release on an RTX 5070 Ti
  • Runs on macOS 15+ (Apple silicon), Windows x64/ARM64 and Linux x64/ARM64, with new .deb and .rpm packages on Linux
  • 3.0 does not auto-update from 2.3.1 and starts fresh, so settings, History and models must be set up again; Voice Action and spoken commands are removed
  • The @opencode launch post drew about 2,400 likes, 1,600 bookmarks and 100k+ views (post)

OpenCode confirms breach: distillation-linked incident hit ~1.4% of Console users; remediating with OpenAI, Anthropic, Google

On 2026-10-17 OpenCode disclosed an overnight breach tied to a large-scale distillation attack affecting about 1.4% of Console users. Affected accounts were emailed; no email means not impacted; only users with external providers linked. Remediation is ongoing with Anthropic, OpenAI and Google. No official blog or GitHub advisory yet; the status page listed no dedicated security incident.

Key Takeaways

  • Official: ~1.4% of Console users; no email means not impacted
  • Scope: subset with external providers linked
  • Remediating with Anthropic, OpenAI, Google; details limited
  • If keys were saved in Console, rotate at each vendor and review usage
  • No official key count, root cause, or confirmed abuse published

OpenCode 2.0 ships: one background service for TUI, web and desktop, Code Mode for all MCP servers, background subagents, and @opencode/sdk

Anomaly published the OpenCode 2.0 launch note on Oct 12: a single auto-started local service shared by the TUI, web and desktop apps; a rewritten server API with the new @opencode/client; @opencode/codemode, which turns MCP servers and OpenAPI endpoints into functions the model composes in scripts (all MCP servers opt into Code Mode by default); background subagents and background shell commands; 80+ internal features rebuilt as hot-reloadable plugins; and @opencode/sdk for embedding the same engine as a library. V1 plugins and the old server API are not compatible.

OpenCode 2.0 ships: one background service for TUI, web and desktop, Code Mode for all MCP servers, background subagents, and @opencode/sdk

Key Takeaways

  • Architecture: one auto-started local background service shared by TUI, web, desktop and @opencode/client scripts; opencode pair connects other hosts
  • Code Mode: @opencode/codemode converts MCP servers and OpenAPI endpoints into script-callable functions; every MCP server defaults to Code Mode (codemode: false opts out)
  • Orchestration: background subagents (background: true, default nesting depth 1) and background shell commands with no default timeout; Ctrl+B moves running work to the background
  • Extensibility: 80+ features implemented as internal plugins, TUI plugins now stable and hot-reloadable; @opencode/sdk is the same code as the CLI
  • Migration: three breaking areas (plugin API, server API/clients, tui.json to global cli.json); upgrade with opencode upgrade --major

OpenCode 1.19.0 opens the upgrade path to OpenCode 2: new plugin and server APIs, auto-updates now manual

OpenCode v1.19.0 (Oct 11) adds opencode upgrade --major and a TUI /update command to move 1.x installs to OpenCode 2 (tagged up to v2.0.26), stops auto-installing updates, and hardens PTY connection validation. The official V2 migration guide lists three intentional breaking changes: plugin API, server API/clients, and terminal client config.

Key Takeaways

  • v1.19.0 shipped 2026-10-11: opencode upgrade --major or TUI /update moves to OpenCode 2; updates are no longer auto-installed
  • OpenCode 2 tags run from v2.0.0 (2026-09-11) to v2.0.26 (2026-10-08); the repo has ~212K GitHub stars
  • Three intentional breaking changes: new plugin API, new server API and clients (@opencode/client), and layered tui.json replaced by one global cli.json
  • V1 plugin implementations do not run on V2 and must be ported; existing agents, commands, skills and opencode.json keep working
  • V2 accepts lsp config but no longer runs language servers or LSP diagnostics; use lint/typecheck/compile commands instead

TimeEvo: Failure-Driven Self-Evolution of Time Series Agents Outperforms Human-Curated Toolkits

Researchers from UIC exposed two structural flaws in autonomous agents reliant on human-curated toolkits: expert-selected tools frequently degrade anomaly detection across all backbones, while unguided self-revision silently breaks 38% of previously correct responses. They introduce TimeEvo, an architecture that clusters runtime failures into capability gaps, synthesizes evidence-only Python tools to address them, and admits candidate tools via paired verification gates. Starting from an empty toolkit, TimeEvo achieves consistent accuracy gains across all ten benchmarks.

TimeEvo: Failure-Driven Self-Evolution of Time Series Agents Outperforms Human-Curated Toolkits

Key Takeaways

  • Exposing Tool Misalignment & Silent Harm: Demonstrates that static expert toolsets paradoxically degrade anomaly accuracy across all LLM backbones, while generic self-revision silently degrades 38% of previously correct answers.
  • Failure-Driven Evolution Pipeline: Systematically clusters execution failures into capability gaps, synthesizes dedicated Python evidence tools, and validates candidates through paired admission gates.
  • Zero-Bootstrap Superiority & Cross-Model Transfer: Starting from a completely empty library, TimeEvo boosts performance across ten benchmarks and three backbones; tools evolved on cheap models reliably transfer gains to frontier foundation models.
