xAI published the full Rust source for Grok Build under Apache 2.0. Agent loop, TUI, tool dispatch, plugin system, MCP support, subagent orchestration. 20,400 stars in four days.
The timing tells the real story. A researcher caught Grok Build silently uploading entire repositories to xAI's cloud infrastructure. The backlash was immediate. Days later: Apache 2.0.
This is the first frontier lab to open-source a production coding agent harness that runs fully local-first. Point it at any inference endpoint via config.toml. Your models, your hardware, your data stays home.
Also in this issue:
- Google ARD — open standard for agents to discover tools across orgs
- 1Password for Claude — zero-trust credentials for browser agents
- Microsoft Agent Framework 1.11 — nudge a running agent mid-turn
- AWS Lambda One-Click Agent Prompt — serverless MCP from the console
- Vercel Eve — your agent is a folder
- Paper: E3 — your coding agent wastes 91% of its tokens
- Tool of the Week: Amazon Bedrock Managed Knowledge Base — enterprise RAG in one primitive
The protocol wars went public
Google, Microsoft, Salesforce, Snowflake, and ServiceNow backed A2A against Anthropic's MCP. AWS shipped a reference implementation composing 5 open protocols in one framework. The fight for the enterprise agent socket is on.
This is Issue #22 of The Agentic Engineer — a weekly newsletter for developers building with AI agents.
