Summary

Anthropic announced “Code with Claude,” its first developer conference, scheduled for May 22, 2025 at The Midway in San Francisco. Application-based attendance (limited capacity). Focus: hands-on workshops on Anthropic API, CLI tools, and Model Context Protocol (MCP); sessions on Claude Code, agent implementation, and tool use patterns from Anthropic’s technical teams. Exec and product team presentations; office hours with technical staff.

Implications

• Developer relations / first in-person developer event. The fact that Anthropic held its first developer conference in 2025 (after two years of API availability) indicates that the developer ecosystem reached a scale that warranted direct cultivation. The MCP and Claude Code focus confirms these as the primary developer bets.
• May 22, 2025 timing. Code with Claude happened ~2 months after the Series E ($61.5B) and coincided with the ASL-3 activation period — Anthropic was signaling developer commitment at the same time as safety escalation. These are complementary, not contradictory, narratives.
• MCP and agent implementation as center stage. Centering the conference on MCP (Model Context Protocol) and agent implementation signals that Anthropic’s developer strategy was shifting from “use our API” to “build agents on our protocol.” MCP’s subsequent donation to the Agentic AI Foundation (December 2025) was the institutional continuation.
• Watch: what announcements were made at the conference itself; whether it became an annual event; how MCP adoption grew among Code with Claude attendees.
