Best MCP servers for SaaS integrations
Most real work happens across a dozen SaaS apps at once: an email arrives in Gmail, a ticket lands in a CRM, a payment posts in Stripe, a message fires in Slack. Wiring an agent into each one individually means juggling separate OAuth flows, rate limits, and auth tokens for every product. Integration-platform MCP servers collapse that into a single endpoint: one connection that fans out to hundreds or thousands of apps and prebuilt actions, with managed authentication handled for you. The trade-off is breadth versus control, a universal connector covers almost everything but exposes generic actions, while a workflow builder lets you assemble exact multi-step automations. The servers below cover both shapes, each a real MCP server with a verified, current install config.
