AI code assistants like **GitHub Copilot, Cursor, Cody, Codeium, and Lovable** have transformed the developer experience. With a few prompts, developers can scaffold code, generate boilerplate, and even spin up simple apps or integrations in hours instead of days.

The hype is justified: building integrations used to mean wading through API docs, dealing with OAuth flows, and debugging endless API errors. Now, an assistant can generate the initial connector with a single request.

But there’s a gap.

**Scaffolding ≠ Scaling.**

AI assistants excel at creating the *first draft* of an integration. They struggle however to make integrations production-ready: do the exact thing you want them to do reliably and provide sufficient details when something doesn’t work.

This post explores that gap. We’ll examine:

1. The landscape of AI coding assistants in 2025.
2. Why integrations are uniquely challenging.
3. Where assistants hit scaling and maintenance limits.
4. How Membrane bridges the gap by turning generated code into *production-grade, maintainable integrations*.
5. How to connect your IDE or coding agent directly into Membrane using the new CLI workflow.

## **The Current AI Coding Assistant Landscape**

In 2025, developers can choose from a rich ecosystem:

- **GitHub Copilot (now with Spark)**: tightly integrated with GitHub repos, excels at suggesting boilerplate code and patterns directly in VSCode.
- **Cursor**: an IDE purpose-built for AI-pair programming, context-aware of your entire repo.
- **Cody (Sourcegraph)**: optimized for large-codebase navigation, retrieval, and context.
- **Lovable**: a “vibe coding” tool that can generate entire apps from prompts.
- **Windsurf**: strong at auto-completion across larger scopes, with GPT-5 integration.
- **Codeium**: free, fast, and increasingly adopted by open-source developers.

Each of these tools can scaffold integrations: writing OAuth flows, generating API calls, and wiring up SDKs.

For example, developers have shared posts on communities like Reddit, [Dev.to](http://Dev.to) like:

![gemini](https://static.integration.app/gemini_5762170ee9.png)

Or

![bolt](https://static.integration.app/bolt_5c8803e61c.png)

These tools are powerful starting points. But once you go beyond a single prototype integration, cracks appear.




## **Why Integrations Are Harder Than They Look**

An integration isn’t just an API call. A production-ready integration requires:

- **Authentication management**: OAuth2, API keys, token refresh, multi-tenant support.
- **Schema exploration and mapping**: ensuring fields in one system map correctly to another, even as APIs change.
    - Many applications support custom data objects and fields - your code needs to handle them correctly.
- **Error handling**: retries, rate limiting, exponential backoff, partial failure recovery.
- **Testing & monitoring**: logging requests, surfacing failures, alerting customers.
- **Upgrades & maintenance**: APIs deprecate, authentication methods change, customers request new fields.

In isolation, any coding agent can scaffold one of these steps. But across **20+ integrations**? The main issue will be production-readiness, you won’t be able to maintain consistency and reliability. Coding agents need context, which can be very problematic across a complex system.




## **Where AI Code Assistants Hit Their Limits**

Here’s what we see in the wild:

### **1. Inconsistent scaffolding**

Different assistants generate different coding patterns. One developer we saw noted:

> “Kiro, DeepSeek, Jules — they all kept changing their code-style decisions. I always had to take over the keyboard.”

This creates integration sprawl: each connector looks and behaves differently.

### **2. Brittle authentication flows**

A common Reddit complaint:

![backend](https://static.integration.app/backend_36cd9766fa.png)

Assistants scaffold the *happy path* of OAuth, but rarely handle refresh tokens, scope changes, or tenant-specific config.

### **3. Edge-case blindness**

Agents happily generate fetch() calls but don’t account for rate limits, pagination quirks, or throttling rules. These bugs appear only in production, and they erode trust quickly.

### **4. Maintenance drag**

One engineer migrating from Lovable to Cursor put it bluntly:

![switch](https://static.integration.app/switch_814f25043e.png)
Each integration becomes a snowflake — difficult to update at scale.



## **Membrane as the Missing Layer**

This is where **Membrane** comes in.

Membrane is a **universal integration layer** designed for AI-built integrations. Think of it as the **operating system for integrations generated with AI**:

- **AI-native**: provides structured context that assistants can consume.
- **Universal**: supports any SaaS API.
- **Scalable**: built for dozens or hundreds of integrations, not just one.

![Membrane_main_inside_blog](https://static.integration.app/Membrane_main_inside_blog_fb33bcc72a.png)

### **How Membrane Bridges the Gap**

1. **Consistent Connector Framework.** Instead of each agent scaffolding a connector differently, Membrane provides a **consistent runtime and schema** for integrations. Agents generate code *into Membrane's framework*, ensuring maintainability across your entire integration ecosystem.
2. **Authentication handled once.** OAuth flows, refresh tokens, and multi-tenant secrets are abstracted by Membrane. This means your AI assistants don't need to reinvent authentication; they simply plug into Membrane's established auth layer.
3. **Production-grade runtime.** Membrane orchestrates retries, pagination, and error handling. This shields your AI-generated code from the common fragilities that appear in production environments.
4. **Observability baked in.** Every integration running in Membrane has logs, metrics, and monitoring. You won't need to add monitoring as an afterthought - it's already built into the system.
5. **Scale without chaos.** Whether you build 5 or 50 integrations, they all run inside the same Membrane runtime — reducing drift and making upgrades easy.

**Membrane is that foundation.**

By combining the creative speed of agents with the robustness of Membrane’s integration layer, teams can finally go from *“It works on my machine”* to *“It works for every customer, every time.”*

For developers, it means fewer late-night OAuth debugging sessions.

For integration engineers, it means consistency across dozens of connectors.

For product leaders, it means faster feature velocity with lower risk.

And for the ecosystem? It means the AI coding revolution finally reaches **production-grade integrations**.

AI code assistants like GitHub Copilot, Cursor, Cody, Codeium, and Lovable have transformed the developer experience. With a few prompts, developers can scaffold code, generate boilerplate, and even spin up simple apps or integrations in hours instead of days but not production-grade integrations. Find out why.

The Promise vs. Reality of AI Code Assistants for Product Integrations

The SaaS industry is seeing a rapid evolution in how users interact with software. Increasingly, users expect to describe what they want in natural language and have intelligent agents handle the details; whether that means automating workflows, connecting data across tools, or simply reducing manual steps.

AI agents are emerging as a practical solution to these expectations. They can:

- Interpret user intent from natural language
- Automate multi-step workflows
- Reduce friction and context switching for end users

Most notably, they can discover and use *tools -* allowing them to perform actions in external systems.

However, the real challenge is not just building an agent, but enabling it to work across the vast and ever-changing landscape of SaaS integrations.

## **The Integration Challenge in SaaS**

While the promise of AI agents is compelling, there’s a significant hurdle: integrations. Most SaaS products support a limited set of integrations, typically built and maintained in-house. This approach has clear limitations:

- Users want to connect to a wide variety of tools, many of which your team may not have prioritized.
- Building and maintaining direct integrations is resource-intensive and can slow down product development.
- Agents that only work with a handful of integrations can’t deliver on the promise of *true* automation.

As AI agents become more central to the SaaS experience, expectations are rising. Users will expect agents to facilitate much more than an abstracted conversation with ChatGPT. They’ll expect them to take action across their entire workflow, using any app they rely on. This means agents need to:

- Access tools from any app in the user’s workflow
- Make intelligent decisions about when and how to use these tools
- Efficiently collect and process the context needed to invoke them

Scaling these requirements across the ever-growing SaaS ecosystem is a major technical challenge.

AI Agents and the Future of SaaS Integrations

## Integration Expectations Are Changing

Today’s users expect their favorite SaaS tools to “just work together.” Increasingly, they also expect AI agents to help manage those connections — handling tasks across apps, surfacing insights, and taking action on their behalf.

But traditional SaaS integrations are time-consuming to build and brittle to maintain. Building a direct connection to every app your users want? Not scalable.

That’s where MCP comes in.

---

## What is MCP?

The **Model Context Protocol (MCP)** is an open protocol that bridges the gap between AI applications (like LLM-powered agents) and the world of tools and data they need to access — especially within the SaaS ecosystem.

At its core, MCP provides a standardized way for agents to discover, access, and invoke external tools, regardless of where they live or how they’re built.

It follows a client-server architecture:

- **MCP Servers** expose capabilities as standardized “tools.”
- **MCP Clients** (often embedded in AI apps or agents) connect to these servers, discover available tools, and invoke them.
- **MCP Hosts** are environments like Claude Desktop, IDEs, or custom agents that use MCP clients to access tools.

Because MCP is modular, you can add new tools dynamically without changing anything about the AI application itself.

---

## Why MCP Matters: A Universal Agent-Tool Interface

The future of SaaS and AI agents isn’t just about answering questions, t’s about taking action.

To do this well, agents need to:

- **Discover tools dynamically**, based on the user’s context and connected accounts.
- **Invoke actions** across apps (e.g. send an email, create a calendar event, update a CRM record).
- **Manage permissions and security** in a consistent, auditable way.

MCP makes this possible by giving agents a universal “language” for interacting with tools. With MCP, agents can:

- Orchestrate workflows across multiple SaaS apps
- Adapt instantly as new integrations become available
- Deliver a seamless, action-oriented experience to users

---

## A Practical Example

To see MCP in action, check out our [AI Agent Example](https://ai.examples.integration.app/), powered by the **Integration App MCP server**. This server exposes all actions from Membrane as MCP tools. Key features of our MCP Server:

- **Easy setup**: Deploy locally or remotely, and connect to your agent with Integration App credentials.
- **Dynamic tool selection**: Only relevant tools are enabled based on the user’s query.
- **Session management**: Persistent chat sessions maintain context across interactions.
- **Security**: Access is secured and auditable via Integration.app tokens.

This setup lets developers and product teams:

- Access thousands of SaaS integrations as tools
- Dynamically invoke the right one based on user requests
- Scale with new integrations — no additional engineering required

---

## Conclusion

MCP is redefining how SaaS apps integrate — not through brittle point-to-point connections, but by enabling AI agents to act intelligently across an open ecosystem of tools.

For integration owners and product teams, adopting MCP means building agents that are more capable, more adaptable, and easier to scale.

Ready to try it? The [Integration App MCP Server](https://github.com/integration-app/mcp-server) is a practical, open-source way to start — and it works out of the box with thousands of integrations.


Today’s users expect their SaaS tools — and now, AI agents — to just work together. But traditional integrations are hard to scale. Model Context Protocol (MCP) changes that by giving AI agents a universal, secure way to discover and invoke tools across apps. Learn how MCP powers dynamic, action-oriented workflows — and how you can try it today with the open-source Integration App MCP Server.
