Every API Is a Tool for Agents - Matt Carey, Cloudflare#

MCP Dev Summit North America 2026 digest Program Adjacent pick 2–3 April 2026

Abstract

Matt Carey, Agents and MCP, Cloudflare; maintainer of the official MCP TypeScript SDK

  • Why: Reframes the context-limit problem in a way that changes build-vs-expose decisions: the context limit is an agent problem, not an MCP problem — so you shouldn't hand-build cherry-picked MCP servers at all.
  • What: Cloudflare's techniques (codemode, tool search) for making complete APIs accessible to agents through MCP without hand-writing tool definitions — motivated by their REST OpenAPI spec being over 2.3 million tokens — plus TypeScript SDK work making stateless servers the default (from abstract only).
  • How: Server-side on-demand tool discovery, treating APIs like CLIs (self-discoverable and documented by design) so the full API surface becomes agent-accessible.
  • Where applicable: Any organization with large REST APIs it wants agents to use; Cloudflare-scale motivation but the pattern is general. Complements the stateless-transports keynote.
