MCP connectors by com.moltlinestudio.mcp

Deterministic date math agents get wrong, done in code over MCP: business_days adds and counts working days with holiday awareness, meeting_overlap finds shared windows across UTC offsets including half-hour zones, recurrence_expand generates concrete dates, with deadline_planner and sla_due in the premium tier. Every failure mode returns a structured error.

A fully free linter for agent skill files: lint_skill validates YAML frontmatter, structure, size budgets, and safety phrasing with a pass/fail verdict; packaging_check validates zip layout against marketplace rules; plus regex_test, json_validate, diff_texts, and cron_explain for skill authors. No license or account required.
