Autron Core

Brings agent identity primitives to Claude: generate DIDs (key/web/dns flavors), create and verify agent cards, handle delegation tokens with scope checks, and manage reputation through endorsements. Exposes cryptographic operations for Ed25519/secp256k1 signing, payment receipts on Solana, and escrow management. You'd reach for this when building multi-agent systems that need portable identity, permission chaining, or on-chain settlement without rolling your own JWT verification and key handling. Ships with a local SQLite registry and MCP SSE server for agent discovery. The web DID resolver handles .well-known/did.json fetching with SSRF protection, so you can host agent identities on your own domain.
