What Claude Desktop is and what MCP unlocks
Claude Desktop is the standalone Claude app from Anthropic. The differentiator is Model Context Protocol, an open standard that lets Claude read from and write to external tools through local servers. With MCP wired, Claude can search your Notion workspace, post to Slack, file a GitHub issue, or run a SQL query, without you copying and pasting.

Quick answers

- What is Model Context Protocol?
- MCP is an open standard from Anthropic that lets AI assistants connect to external tools and data sources through local or remote servers. It is being adopted by other vendors as the cross client standard for tool use.
- Is the Anthropic API rate limited?
