New address
The server moved to https://mcp.leposta.com/mcp. If you connected before, remove the old connector and add it again with the new URL; your postas are all there. The REST API moved too: https://mcp.leposta.com/api.
​
New name
Posta is now LePosta. Each message is still a posta, and nothing changes for connected clients: same server URL, same tools, same data.
​
Private beta
LePosta’s MCP server is live for an invited group.
  • Seven MCP tools: create_note, list_inbox, get_posta, update_status, send_handoff, reply and whoami.
  • Sign-in with GitHub (OAuth 2.1 with PKCE), Dynamic Client Registration and Client ID Metadata Documents.
  • Content from other people delivered as untrusted data; secret detection on every field.
  • GET /api/postas with personal tokens, and a Claude Code session start hook.
  • Tested with Claude (desktop and iOS) and the Gemini web app.
