Romuald Członkowski	551445bcd5	fix: revert to Node 20 and use granular NPM token NPM classic tokens were revoked on Dec 9, 2025. OIDC trusted publishing requires npm >= 11.5.1 which caused lockfile sync issues with npm ci. Reverted to Node 20 with granular access token approach: - Removed OIDC permissions block - Removed npm upgrade step - Restored NODE_AUTH_TOKEN usage - Removed --provenance flag User created new granular token with "Bypass 2FA" enabled.

Romuald Członkowski	c6f3733fbd	fix: upgrade npm for OIDC trusted publishing support OIDC trusted publishing requires npm >= 11.5.1, but Node.js 20/22 ships with npm 10.x. Added explicit npm upgrade step before publish. Also upgraded to Node.js 22 for better npm compatibility.

Romuald Członkowski	6e85c68d62	chore: bump version to 2.29.3 to trigger OIDC publish The previous workflow re-run used cached old workflow code with NPM_TOKEN.

Romuald Członkowski	fa7d0b420e	ci: switch NPM publishing to Trusted Publishing (OIDC) Replace static NPM_TOKEN with OIDC-based authentication for improved security. This uses NPM's Trusted Publishing feature which: - Eliminates need for long-lived tokens - Provides provenance attestation - Is the recommended approach by npm Requires configuring Trusted Publishing in npm package settings: - Repository owner: czlonkowski - Repository name: n8n-mcp - Workflow filename: release.yml Conceived by Romuald Członkowski - www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2025-12-12 13:24:25 +01:00
