MCP (Model Context Protocol) is an open pattern for giving AI tools structured access to external systems — filesystem, HTTP APIs, browsers, documentation indexes — without pasting secrets into chat.
Problem it solves
Without MCP, every integration is a custom plugin script. With MCP, your IDE can call «fetch library docs» or «snapshot this URL» the same way across projects.
Useful MCP servers for web studios
- Context7 / docs: up-to-date framework references
- Browser: QA on staging without manual screenshots
- Filesystem: scoped repo reads (never production credentials)
Security basics
- Run MCP only on dev machines or CI sandboxes
- Deny write access to
.envand SSH keys - Log which tools the agent invoked
