AI SDK Opens Harness Layer To ACP

Vercel’s AI SDK now supports any Agent Client Protocol-compatible harness through the new @ai-sdk/harness-acp meta adapter. Developers can define custom adapters with createACP and run them through HarnessAgent.

// ANALYSIS

This turns ACP into a practical expansion point for AI SDK’s harness ecosystem, though direct adapters remain preferable when available.

–Supports harnesses without first-party AI SDK integrations
–Reuses ACP for authentication, permissions, sessions, and runtime mapping
–Keeps HarnessAgent’s unified interface across custom and built-in harnesses
–Direct adapters may still expose deeper, vendor-specific behavior
–Broadens AI SDK’s role from model toolkit to agent-runtime layer
