MCP
Use 42A from inside Claude Desktop, Claude Code, Cursor, and other MCP clients.
The Model Context Protocol is an open standard for letting AI assistants safely call into external tools. 42A ships it two ways: @42a/mcp, a stdio server you run locally, and a hosted remote server at https://mcp.42a.ai/mcp you just connect to.

Install
