Agentic AI Foundation: Microsoft, Google, OpenAI and Anthropic join forces for open standards

The biggest competitors in AI have decided to collaborate. Microsoft, Google, OpenAI, Anthropic, along with AWS, Block, Bloomberg and Cloudflare as platinum members, back the Agentic AI Foundation (AAIF), announced by the Linux Foundation on December 9, 2025.

Why this alliance matters

Companies that fiercely compete in the AI market now collaborate on open standards under neutral governance. This points to:

Before	Now
Each company with proprietary protocols	Shared, open standards
Incompatible AI agents	Cross-platform interoperability
Vendor lock-in	Freedom to switch providers
Ecosystem fragmentation	Unified ecosystem

The 3 founding projects

1. MCP (Model Context Protocol) - Anthropic

The Model Context Protocol is an open standard that defines how AI agents connect to external applications.

Benefits for developers:

• Single protocol to connect any AI to your services
• Switch AI providers without rewriting integrations
• Open source community developing connectors

2. Agents.md - OpenAI

AGENTS.md is an open Markdown format for giving instructions to coding agents. It complements the README: the README is for humans, and AGENTS.md holds the context agents need (build steps, tests, conventions). According to the Linux Foundation, it is already used by more than 60,000 open source projects:

# AGENTS.md example

## Instructions
- Follow existing code conventions
- Run tests before commits
- Don't expose secrets in logs

## Context
- Framework: Next.js 14
- Testing: Jest + Playwright
- Style: ESLint + Prettier

Benefits:

• A predictable place for instructions to any coding agent
• Living documentation of project conventions
• The README stays clean and focused on people

3. Goose - Block

Goose is an open source, local-first AI agent framework developed by Block (formerly Square) that integrates with tools through MCP:

Feature	Description
Open source	Fully open code
Extensible	Extensions via MCP
Multi-model	Works with multiple LLM providers
Local-first	Runs on your own machine

Implications for businesses

Immediate opportunities

1. Adopt MCP now: If you’re building AI integrations, use MCP from the start
2. Create AGENTS.md: Document instructions for AI agents in your repositories
3. Evaluate Goose: As an open source alternative to proprietary agents

For technical leaders

1. Risk reduction: Open standards = less lock-in
2. Safe investment: Building on MCP is a long-term investment
3. Talent: Look for developers with agentic AI experience

The bigger picture: 2026 is the year of agents

This alliance confirms what analysts predict: 2026 will be the year of agentic AI. AI agents will move from impressive demos to real productivity tools.

“AI agents will proliferate in 2026 and play a bigger role in daily work, acting more like teammates than tools.” — Vasu Jakkal, Corporate Vice President, Microsoft Security
