"Session" matching MCP servers:

One MCP server holding a live session with every client's account at once, so one agent can read across a dozen businesses and write inside only the one you name. It forwards each provider's own MCP tools (Cloudflare, Vercel, Resend, Supabase, Linear, Notion, Sentry, Netlify and more) with that client's credentials, and adds deterministic DNS and email checks that never call a model.

Connects an MCP client to an existing classic Outlook session on Windows so agents can browse stores and folders, list recent messages, run literal text and metadata searches, and read plain-text bodies with attachment metadata. All access is strictly read-only, with no sending, deleting, moving, or network connections of its own.
