Big Software Strikes Back: Five Giants Launch ARD, a Rival to Anthropic's MCP

The biggest names in enterprise software just picked a side — their own. Google, Microsoft, Salesforce, ServiceNow and Snowflake agreed to back ARD (Agent Routing and Discovery), a shared standard for connecting AI agents to business software, per reports. The broader coalition reportedly also includes Cisco, Databricks, GitHub, GoDaddy, Hugging Face and Nvidia.

What ARD actually is

Where Anthropic's Model Context Protocol (MCP) standardizes how an agent discovers and calls tools through a conversational interface, ARD's pitch is a layer for agents to discover and route between services autonomously — operating inside existing software ecosystems without a chat window as the bottleneck. Officially, ARD is framed as complementary to MCP and to Google's own Agent2Agent protocol, not a replacement.

Why it's really happening

Read past the diplomacy: MCP has quietly become the industry default over the past 18 months — it's in trading apps, IDEs, operating systems and every major model vendor's stack — and the giants do not love building on a competitor's foundation. Every MCP integration deepens Anthropic's position at the center of the agent ecosystem; ARD is the incumbents' bid to own the wiring themselves. It's a classic standards play: embrace publicly, replace gradually.

What happens next

Standards wars are won by developers, not press releases. MCP's advantage is enormous installed momentum — thousands of servers, first-party support from Anthropic and OpenAI, and two years of tooling. ARD's advantage is distribution: if Microsoft 365, Salesforce and ServiceNow expose their platforms natively over ARD, enterprises may find themselves speaking it whether they chose to or not. The likely outcome is a bilingual world — agents that speak MCP to tools and ARD to the enterprise stack — but the message to Anthropic is unambiguous: the incumbents want the protocol layer back.
