BackEngine is a multi-tenant SaaS platform that ingests all of an organization's customer and prospect communications — Slack threads, emails, call and meeting transcripts, and support tickets — and distills them into structured, queryable context. Raw conversations are processed into signals (categorized, attributed moments), sources (the underlying transcripts, emails, and tickets), and rolling project overviews, all isolated per tenant and scoped by role and access controls. The MCP server exposes this layer over the Model Context Protocol, so an LLM client can query customer signals, reconstruct context, prep for meetings, surface at-risk accounts, and draft grounded outreach from real conversation history — without leaving the chat

The Superserve MCP server lets any MCP client create and control isolated cloud sandboxes - each one a Firecracker microVM that boots in seconds. Your agent can run shell commands, read and write files, install dependencies, and expose a running server as a public preview URL, then pause or delete the sandbox when it’s done. Secrets are brokered by the platform so credentials never pass through the model, and outbound network access is controllable per sandbox. Works with Claude, Cursor, VS Code, Windsurf, and Codex. Run it locally with npx -y @superserve/mcp, or connect to the hosted endpoint at mcp.superserve.ai - both authenticate with your Superserve API key.
