Using Cursor as a Unified Interface for Your Entire Business Stack

LLMs are becoming the new browser.

Instead of clicking through dashboards, you speak or type commands and receive data, actions, or UI on demand.

Why: Reduces context-switching and repetitive clicks, aligning with natural language as the primary interaction layer.

"LLMs are the new browser."

Turn SaaS into programmable infrastructure.

By wiring MCPs to apps like Xero, Playwright, FireCrawl, and Perplexity, every SaaS action becomes an API call triggered by a sentence.

Why: Eliminates manual repetition and enables batch or conditional workflows that were previously impossible across siloed tools.

"how do you turn SaaS, how do you turn SaaS into programmable"

Chain reasoning models with agentic models.

Use thinking models (O3, Gemini 2.5, Claude 4-max) to plan, then hand off to action models (Sonnet 4, Opus 4) to execute.

Why: Maximizes accuracy for complex tasks while leveraging speed and tool-use for execution, reducing hallucination and cost.

"they'll get a thinking model to actually come up with a plan to execute. Then switch over to the agentic model and then actually execute on it."

Generate a canonical LLM.txt for every domain.

Scrape your entire website or knowledge base into a single context file so any agent can reference up-to-date product, pricing, and ICP data.

Why: Prevents hallucination and ensures outbound content, PRDs, or code changes are grounded in ground-truth company information.

"we have a Humbolytics LLM.txt file that is very comprehensive around everything what our product is, how much it costs, what it is, who our ICP is."

Automate UX audits with screenshots + analytics.

Use Playwright to capture live screenshots, pipe them into a custom Cursor mode trained on design/growth, and feed real analytics from your own MCP to prioritize A/B tests.

Why: Shrinks the iteration cycle from days to minutes and surfaces data-driven insights that humans often overlook.

"I also have a UX team that monitors my landing page all the time, take screenshots and gives me feedback based on our analytics data"

Treat accounting as queryable infrastructure.

Connect the Xero MCP once, then ask for P&L, create quotes, or generate payroll reports with plain English commands.

Why: Removes the need to train non-finance teammates on accounting UI and enables real-time financial dashboards deployed via Netlify.

"connect to Xero MCP and list out my profit report for May 2025"

Combine live search, keyword data, and context files for hallucination-free articles.

Use Perplexity MCP to research, merge with keyword density requirements, and inject LLM.txt context to produce ready-to-publish posts.

Why: Ensures factual accuracy, SEO optimization, and brand alignment without manual copy-paste between tools.

"use Perplexity MCP to research top split testing tools and refer to HumbleLytics context file and the keyword data to generate an article"

Replace manual test plans with agentic browser scripts.

Hand Playwright a written test plan; it navigates, clicks, fills forms, and even passes CAPTCHAs while logging results.

Why: Provides continuous integration-grade QA without writing Selenium or Cypress code, making testing accessible to non-developers.

"I can actually get Playwright to follow this test plan to say, go do this, go do that."
