Primary project
MCP Docs
Official explanation of how Cursor plugs into outside tools through MCP.
Layer thesis
How to read this branch of the ecosystem
This is the shortest explanation of what this layer is for and why it matters.
MCP and marketplace integrations are the ecosystem's cleanest answer to context breadth, tool access, and product-connected workflows.

Work patterns
What people actually do here
These workflow slices connect the layer to real usage patterns.
Workflow pattern
Expand context through MCP, not just bigger chat history
The extension layer increasingly solves context problems by connecting Cursor to external systems, documentation, browsers, and tool APIs via MCP and marketplace integrations.
Guardrails
What to remember while exploring
Layer-specific best-practice reminders that keep this branch legible.
Best practice
Treat MCP as the default answer to context breadth and external systems
High-signal integrations increasingly route through MCP rather than giant prompt dumps. That makes tools like docs connectors, browser bridges, and registries strategically important.
