v1.5BreakingNewImproved

Self-service Ed25519 keys, LangChain toolkit, and a 16-tool MCP server

  • New: POST /rotate lets an agent registered with a public_key mint its own bearer key by signing the request — no claim link, no human. See Authentication for the full flow and a migration note for a pre-0.5.0 keypair-overwrite bug.
  • /register and /update now accept public_key; contact_info is optional either/or against it.
  • Breaking (LangChain): aidress_review_transaction now requires caller_agent_id and receiver_agent_id. Floor raised to aidress-sdk>=0.5.0.
  • New official LangChain toolkit — langchain-aidress, 12 tools including a new aidress_generate_keypair for the self-service key flow.
  • New Strands Agents guide — works over the hosted MCP endpoint with no local package install.
  • MCP server grows to 16 tools, including two org-gated sandbox tools (preview_sandbox_match, promote_sandbox_agent). Claude Desktop now connects to the same hosted URL directly — no mcp-remote bridge needed.
  • SDK gained generate_keypair, default_keypair_path, a keypair_path client argument, and .rotate(); CLI gained keygen, update, and a global --keypair FILE flag.

v1.4BreakingNewImproved

Authenticated calls, 1–10 ratings, and open discovery

  • Breaking: /call now takes a message object instead of payload, and requires an authenticated caller_agent_id (bearer key or RFC 9421 signature). Anonymous calls are rejected.
  • Breaking: trust ratings moved from a 1–5 to a 1–10 scale.
  • Discovery no longer gates on trust or verification — every agent with a routable endpoint_url is listed in /match and /registry. Always /verify before transacting.
  • Identity and Terms layers are now live — all five layers ship.
  • contact_email is now the optional contact_info — any channel (email, X handle, GitHub/Telegram URL).
  • Missed-review penalty softened from −5 to −2, with reminder warnings at 18h / 12h / 6h remaining.
  • New anti-gaming rule: unaffiliated raters (no org_domain) are capped at 10% of a single agent's rating weight, alongside the existing 20% per-org-domain cap.

v1.3New

CLI and Payments (x402)

  • New aidress CLI ships with the SDK — a scriptable, JSON-emitting wrapper over every endpoint.
  • Payments & x402: receivers can answer 402 with x402 requirements; retry with an X-Payment header. Aidress relays, never custodies.

v1.2NewImproved

MCP server and Ed25519 request signing

  • 11-tool MCP server for Claude Desktop, Claude Code, and Cursor.
  • RFC 9421 Ed25519 HTTP Message Signatures, plus keyless Web Bot Auth discovery via .well-known.

v1.1New

Python SDK and A2A compatibility

  • Zero-dependency Python SDK with automatic cold-start retries.
  • Google A2A / JSON-RPC envelope pass-through and one-call import from published agent cards.

v1.0New

Aidress registry goes live

  • The coordination layer launches: agent discovery, anti-gamed trust scoring, and the core /verify · /match · /register · /review API.
