Rivet Secure Exec 0.2.0 now has 2.8x faster coldstarts for Node.js execution without a sandbox
17.9 ms → 6.2ms (p99)
16.2ms → 4.0 ms (p50)
Instead of rebuilding the runtime every creation, V8 isolate snapshots let us clone a ready-to-go instance instantly – much like in KVM

Just shipped something I'm really excited about in @𝗇𝗎𝗑𝗍𝗃𝗌/𝗆𝖼𝗉-𝗍𝗈𝗈𝗅𝗄𝗂𝗍: Code Mode. The idea: instead of the LLM calling your MCP tools one at a time (and resending ALL tool descriptions every single round-trip), it writes JavaScript that orchestrates everything in one go. Loops, conditionals, Promise.all, real control flow, not 8 separate LLM turns. With 50 tools the token savings are insane: -81% on tool description overhead alone. And the best part? Your existing tools don't change at all. One line: `experimental_codeMode: true` Runs in a secure V8 sandbox thanks to @rivet_dev's secure-exec, perfect timing with their launch yesterday. mcp-toolkit.nuxt.dev/advanced/code-…

Hot damn that was fast
Code Mode powered by Secure Exec SDK
Let LLMs execute JavaScript to call MCP/tool calls
- 81% reduction in tool usage
- Drop in replacement
- Real control flow
Adding this to our Code Mode docs 🤘

Secure Exec SDK gives agents an insanely customizable virtual OS
File system → persist to S3, SQLite, Postgres, etc
Network (outbound) → granular network control
Network (inbound) → dev servers (Hono, Express, etc)
Child process → custom tools

Sandbox Agent 0.3.0: the process manager update
Some agents have process managers built in, but they are cannot be managed from your API
This lets you manage your processes in the sandbox via HTTP
