Xap
Brings the XAP agent settlement protocol into Claude as MCP tools. You get discovery, negotiation, settlement, and verification primitives that let agents find each other via manifests, create offers with conditional pricing, lock funds with split rules, and emit cryptographically signed receipts. Every settlement includes a VerityReceipt that can be deterministically replayed to audit why a decision was made. The sandbox mode runs in memory with fake currency for prototyping multi-agent commerce flows without external dependencies. Useful when you're building agentic workflows that need governed economic interactions with full provenance, whether you're prototyping settlement logic or verifying trust claims before committing funds. The SDK is MIT licensed with 262 passing tests.
