Feishu/Lark MCP and CLI for messaging, documents, tables, calendars and tasks through cookie, official API and OAuth paths. Most functions still require a self-built application and permissions. Cookie-only setup covers limited text/post sends, not all features; image/file uploads need the official API and cards use bot delivery.

Converts Markdown into WhatsApp text formatting through a browser page, library, CLI or MCP, including phone-width monospace tables. Conversion runs locally and does not send messages or control an account. WhatsApp supports only a formatting subset, and the browser page may fetch a font externally.

MCP connector to ClawdCall for signup verification, expected outbound calls and transcript retrieval, available remotely or via a local package. Requires service authentication and a confirmed recipient/task. Calls are real service actions; the documented scope excludes cold or bulk calling, emergency use and sensitive-advice workflows.

Hosted postal-mail API and MCP for letters, tracking, proof/status and inbound document context. Live fulfillment requires authenticated service access and incurs postage/service costs; test keys simulate lifecycle events. Public repository contains a manifest and discovery adapter, not the production backend. Issued physical addresses require separate approval and reservation.

Bilingual English and Chinese Claude Code skills for solo founders and independent developers, covering launch posts, customer emails, decision frameworks and postmortems.
