Ecosystem Mirror — n8n 2.5.0, MCP 0.2.0, Skill Refresh

· 4 min read
AGIRAILS Core Team

@agirails/sdk@4.0.0 shipped on 2026-05-19. Within 24 hours the rest of the ecosystem followed: n8n-nodes-actp@2.5.0, @agirails/mcp-server@0.2.0, and a refresh of the Claude plugin, Claude skill, and OpenClaw skill. All three npm packages now publish through the same workflow-attested pipeline; all three documentation surfaces are aligned with the V3 mainnet redeploy.

n8n Community Node — n8n-nodes-actp@2.5.0​

npm install n8n-nodes-actp@2.5.0
  • @agirails/sdk peer bumped to ^4.0.0
  • First workflow-attested publish for the n8n node — OIDC + sigstore + SLSA provenance, same flow as the SDK
  • Lockfile-consistency fix (the previous lock had an orphaned arconnect entry that broke npm ci on Linux CI)
  • uuid pinned to ^9 via overrides — keeps the CJS shape for Jest under newer transitive resolutions
  • No hardcoded contract addresses; the node reads them via SDK getNetwork(), so the V3 mainnet swap is automatic on this bump

MCP Server — @agirails/mcp-server@0.2.0​

npx @agirails/mcp-server

For Claude Desktop / Cursor / Windsurf / VS Code with MCP — gives any context window the same 20 tools (5 discovery + 14 runtime + 1 protocol bootstrap), now tracking SDK 4.0.0.

  • @agirails/sdk dep bumped ^3.3.0 → ^4.0.0
  • Workflow-attested publish — first attested release of the MCP server
  • All 125 tests pass under SDK 4.0.0; no MCP-side code changes were needed (the SDK API surface used — ACTPClient, Agent, AgentRegistry, getNetwork, provide, request — is fully compatible)

Documentation surfaces — three skills refreshed​

The three Claude/AI-agent documentation packages all received a 4.0.0 refresh:

agirails/claude-plugin (Claude Code marketplace)​

Eight files updated:

  • commands/upgrade.md rewritten — drops the ancient 1.x → 2.0 and 2.0 → 2.1 migration sections, adds a 3.x → 4.0.0 migration section that's actually relevant (mainnet address swap, x402Relay drop, X402Adapter auto-registration), version history table bumped to include 4.0.0 / 3.5.3 / 3.3.0
  • commands/init.md — example --version flag bumped from 3.0.0 to 4.0.0
  • commands/pay.md — drops the now-deprecated manual X402Adapter registration code; payment summary updated for x402 v2 zero-fee semantics
  • skills/agirails-typescript/SKILL.md — version bumped, the WRONG/CORRECT troubleshooting example replaced with the auto-registration pattern
  • skills/agirails-patterns/SKILL.md — version bumped, two manual-registration code blocks replaced with metadata opt-in pattern
  • skills/agirails-core/SKILL.md — fee comparison table fixed (x402 v2 is zero AGIRAILS fee, not "same as ACTP"); X402Relay-on-mainnet language replaced with deprecation note
  • skills/agirails-security/SKILL.md — X402Relay fee-enforcement bullet rewritten for v2 facilitator model
  • README.md — added a "What's new in v4.0" callout at the top with the six high-impact changes integrators see

agirails/claude-skill (generic Claude skill)​

  • Fee section in SKILL.md refreshed — ACTP path keeps 1% / $0.05 floor (now enforced on-chain via MIN_FEE), x402 path documented as zero-fee buyer→seller via @x402/fetch + facilitator
  • "Current state (v4.0.0, 2026-05-19)" callout added at the top of the skill — mainnet V3 redeploy, AIP-14 dispute bonds, MIN_FEE on-chain, INV-30, Sourcify EXACT_MATCH, workflow-attested publish

agirails/openclaw-skill (ClawHub OpenClaw skill)​

  • Frontmatter version: 3.0.0 → 4.0.0
  • Floor references @agirails/sdk@3.3.0+ → @agirails/sdk@4.0.0+ (kept the historical "deprecated AS OF SDK 3.3.0" timestamps where relevant)
  • "What's new in v4.0.0" callout added below the title

All three skill repos auto-sync from GitHub main to their respective distribution channels: the Claude Code plugin marketplace (claude-plugin), Anthropic's generic Claude skill format (claude-skill), and ClawHub via OpenClaw (openclaw-skill). No version tag or npm publish involved — the docs propagate on the next consumer refresh.

What didn't ship in this wave​

  • Python SDK on PyPI (agirails) — python-sdk-v2 still on 2.4.0 with pre-V3 addresses. The mirror is queued; the wider story (poetry publish path, dependency cleanup, address surface refresh) takes another focused session.
