Overview

Cursor IDE supports the Model Context Protocol (MCP) for extending AI agent capabilities with custom tools. This guide walks through setting up MCP servers in Cursor, from basic file system access to database connections, web browsing, and custom tool development. Covers the mcp.json configuration file format, environment variable injection, transport protocols (stdio, SSE, streamable-http), and security best practices for each server type.

  • -Configuration file format and options
  • -Environment variable setup for credentials
  • -Transport protocol selection guide
  • -Multi-server configuration with priorities

Security Considerations

MCP servers in Cursor run with your user permissions. A malicious or compromised MCP server has full access to your filesystem, network, and environment variables. Only install MCP servers from trusted sources. Review server code before installation. Never configure MCP servers that point to untrusted remote endpoints.
