Three Carta plugins hit the marketplace overnight while Airtable joins as the structured data backbone for AI agents.

Anthropics shipped Carta's full suite into the knowledge-work-plugins marketplace: cap-table for issuers, CRM for fund managers, and investor reporting for LPs, all connecting to Carta's remote HTTP MCP server [1]. Airtable landed in parallel as the operations layer for agent-driven workflows, bundling its official MCP server with schema and record management skills [2]. Both moves signal the same bet: AI agents need professional-grade integrations, not toys. On the plugin infrastructure side, the official registry is getting tightened. The Convex entry was renamed from `convex-backend` to `convex` to match naming conventions across the database layer, bumping to v1.0.1 [3]. Meanwhile, 68 plugin SHAs were validated and pinned in a single batch [5], a sign the marketplace is hardening around a stable core. Windows support got fixed too. The agentic commit reviewer was silently no-opping on Windows due to path resolution bugs in both the bootstrap layer and the consumer glob. Both issues are now patched [4]. Claude Code and Agent SDK bumped to 2.1.153 and 0.3.153 respectively [6].
