Release Release v1.6.1 · kesslerio/attio-mcp-server

New dedicated list configuration tools, npm provenance for supply chain verification, and Docker build fix.

What's New

create-list tool (#1195, #1196) - Dedicated list creation with template expansion (sales_pipeline, recruiting_tracker, support_queue), parent-object validation against workspace objects, and dry-run preview
update-list-configuration tool (#1195, #1196) - Dedicated list update with immutable field detection (rejects parent_object changes), dry-run preview, and categorized error guidance
Shared ListConfigurationValidator for parent-object validation, immutable field detection, template expansion, and error categorization — consumed by both dedicated tools and universal create/update strategies (#1195)
npm provenance publishing — every release is now cryptographically linked to the GitHub Actions build and source commit via Sigstore, enabling supply chain verification with npm view attio-mcp --json | jq .attestations
.npmrc with save-exact and strict-peer-dependencies for safer installs

Universal list create and update paths now validate parent_object and detect immutable fields before API calls (#1195)
List error categorization prefers HTTP status codes over fragile string matching (#1196)
Docker build stage now uses oven/bun:1 instead of node:20-slim for consistency with the project's package manager

npm install -g attio-mcp
