Open-source TypeScript beta for agentic apps: define a capability once and expose it to UI, agent, HTTP, CLI, MCP, and A2A so Claude/ChatGPT/Cursor can call the same actions humans click—skip screen-scraping computer-use for lower tokens.
Kondo’s WhatsApp MCP (Streamable HTTP at mcp.trykondo.com/mcp) lets Claude, ChatGPT, Cursor, Claude Code and Copilot search chats, read messages, draft replies, label, reminder and archive while Kondo Desktop holds the local WhatsApp session—no send tool, so nothing leaves as a message until you press Send. Relay keeps chat content off the cloud; Desktop must stay open. MCP on Business/Enterprise plans; install skill at trykondo.com/skills/kondo-whatsapp.md.
Marc Lou’s MailCheap exposes Streamable HTTP MCP at https://mailcheap.ai/mcp so ChatGPT, Claude and Grok Bot connect with OAuth (no key to copy); Claude Code, Codex and Cursor use a bearer API key. Agents can draft campaigns, send tests, schedule issues and read stats; schedule/send tools are marked destructive and ask before sending. Open-source / self-host option; pay only for SES-style sends vs beehiiv-class plans.
Show HN (Oct 16): Stoke Money is a personal-finance app centered on projected cash flow (not budgets); Pro adds MCP so Claude/ChatGPT can import PDFs, categorize trips, and plan transfers against the forecast—read-only or read/write scopes, revoke anytime; Plaid sync, AES-256 at rest.
SuperCompress v2 compresses context against the query (keeps answer-critical lines verbatim): ~64% mean cut on their B5 coding-agent suite with 24/24 evidence-retention passes; MCP/plugin for Cursor/Claude Code/Codex plus hosted API and open weights.
