The mcp command starts the Better Fullstack MCP server. Agents can use it to inspect schemas, validate compatibility, preview generated files, create projects, and add supported features to existing projects.

npx create-better-fullstack@latest mcp

The server uses stdio transport. Configure your MCP client to launch the command and communicate over standard input/output.

Client Examples

Claude Code:

claude mcp add --transport stdio better-fullstack -- npx create-better-fullstack mcp

Generic MCP client config:

{
  "mcpServers": {
    "better-fullstack": {
      "command": "npx",
      "args": ["-y", "create-better-fullstack", "mcp"]
    }
  }
}

Safety Notes

  • bfs_plan_project does not write files.
  • bfs_create_project writes files but does not install dependencies.
  • bfs_add_feature mutates an existing Better Fullstack project and does not install dependencies.
  • Agents should call bfs_get_guidance and bfs_check_compatibility before project creation.
  • docs opens the public documentation site.
  • builder opens the interactive Stack Builder.
  • sponsors shows Better Fullstack sponsors.
