A documentation to help AI IDE like Cursor or Github Copilot to help you build your app faster
You new features will be shipped at 10x speed. Thanks to tech doc optimized to help AI.
Discover how each feature works.
Model Context ProtocolYour users plug Claude, ChatGPT or Cursor into their account with a browser login. You expose your own features as tools, one file each.
Claude wants to access your account
Signed in as maya@northstar.io. You will be sent back to claude.ai.
It will be able to
Read your workspaces, their members and their credit balance
In these workspaces
An OAuth 2.1 server with PKCE, rotating refresh tokens and dynamic client registration. Users pick the workspaces and revoke access from Connected apps.
@Injectable()export class ProjectToolset implements McpToolset { constructor(private readonly projects: ProjectService) {} readonly tools = [ defineMcpTool({ name: 'list_projects', description: 'Lists the projects of a workspace.', inputSchema: z.object({ workspaceId: z.uuid() }), scope: 'read', handler: ({ workspaceId }, context) => { if (!context.workspaceIds.includes(workspaceId)) { throw new McpToolError('Workspace not granted.'); } return this.projects.findByWorkspace(workspaceId); }, }), ];}Write a toolset class and list it in mcp-toolsets.ts. Every call is bound to the user and the workspaces they granted, never to what the model asks.
A lot of optimizations and a pinch of secret sauce to make you extraordinarily productive.

I'm trying VS Code Cursor + Sonnet 3.5 instead of GitHub Copilot and I think it's now a net win… I basically can't imagine going back to 'unassisted' coding at this point.

All this talk of Claude + Cursor and becoming capable of building anything you put your mind to (no matter your skill set) is warranted. If this is the future, I want to live in it.

I've been using Claude 3.5 for a couple of days now and I must say this is insane… It's incredibly good at writing code fast, and nails every question on the first try.

I built 2 SaaS products in 1 month. To move that fast, I used Dopamine as a solid, turnkey foundation that lets me abstract away all the generic SaaS boilerplate.
