AI digest: 2026-10-23

Highlights

• MCPtoCodeMode: a new MIT MCP server that puts all your MCP servers behind three tools (search, describe, execute), so the agent chains calls in sandboxed JavaScript. Try it with claude mcp add codemode -- npx -y mcptocodemode serve.
• Claude Code 2.1.309: closes several sandbox gaps (shell startup files ran unsandboxed, the --mcp-config file could be edited). sed -i now gets a normal prompt, and claude ultrareview scripts need --trust-workspace.
• Agent Skills goes to the Agentic AI Foundation: the skills standard now has the same neutral, Linux Foundation governance as MCP. Anthropic counts over 70 platforms that support it.

New sources

Agents and tooling

• Claude Code releases 2.1.308 and 2.1.309: sandbox and permission hardening, sed -i and ultrareview changes, /claude-api on multiagent_20261001.
• MCPtoCodeMode: a code-mode proxy for any MCP servers, with a QuickJS sandbox and one-line setup for Claude Code, Codex, and others (from today's GitHub trends).
• Ribbon: a Claude Code plugin showing usage left and prompt-cache warmth above the prompt (from today's GitHub trends).
• Donating Agent Skills to the Agentic AI Foundation: the spec, name, and agentskills.io move to the AAIF, with multi-company maintainers.

Frameworks and libraries

• Pydantic AI v2.60.0: Docker/Podman and BoxLite sandboxes, SmartSearch, RelevanceCompaction, per-run MCP auth.
• Microsoft Agent Framework (Python) 1.23.0: breaking move to MCP 2.x and stricter AG-UI auth.
• Ollama v0.40.9: Phonon speech on Apple Silicon, d3 decision models, Flint on Linux and Windows.

Models

• Claude Models on Google Cloud (Anthropic managed): Anthropic's own API through Google Cloud IAM and Marketplace billing, with fast mode and Managed Agents.
• OpenAI Decisions API generally available: 400 questions per request, cached shared input, images, input_json.
• Flint model card (Recursive): confirms the architecture and licence. The benchmarks are developer-reported only (gap fill).
