This Free Tool Makes Cursor 10x Smarter

Summary

In this video, the speaker discusses frustrations with Cursor's outdated documentation indexing, particularly in the fast-evolving JavaScript world. They demonstrate how Cursor fails to keep up with the latest Next.js features, using the 'onNavigate' event handler as an example. The speaker introduces 'Context 7', a free tool that effectively addresses this issue by integrating with over 850 libraries, offering up-to-date documentation with relevant code examples. The video also highlights the ease of installation, and the tool's potential to streamline coding workflows by eliminating outdated or incorrect documentation.

Q & A

What problem does the user face with Cursor's built-in documentation indexing?

The user faces the issue that Cursor’s documentation indexing is often outdated, especially with fast-evolving libraries like Next.js. It doesn't provide the latest examples or use the newest event handlers, resulting in code that may not work with the latest features.

How does the user attempt to solve the issue with Cursor?

The user attempts to solve the issue by tagging the latest documentation, like the Next.js docs, in Cursor’s indexing feature. However, this doesn’t always yield the correct or up-to-date code, especially when dealing with new event handlers or features.

What is the new feature from Next.js that the user is trying to work with?

The user is trying to work with the new `onNavigate` event handler introduced in Next.js 15.3. They want to use this feature in their project but find that Cursor’s outdated documentation doesn't support it.

How does the new solution, Context 7, differ from Cursor's built-in documentation indexing?

Context 7 improves on Cursor’s indexing by providing more relevant and updated code examples directly from the source documentation of libraries like Next.js. Unlike Cursor, which may use outdated models, Context 7 fetches the latest code snippets and avoids unnecessary filler text.

What are the key advantages of using Context 7 for documentation indexing?

Key advantages of Context 7 include up-to-date documentation indexing, no outdated or hallucinated code, and the ability to pull concise, relevant code examples directly from official sources. It supports over 850 libraries, including popular ones like Next.js and MongoDB.

How does Context 7 handle new and emerging libraries?

Context 7 continuously grows by indexing new libraries and offering documentation updates. It can even support requests to add specific documentation, ensuring that developers always have access to the most current and relevant information.

What is the process to set up Context 7 in Cursor?

To set up Context 7 in Cursor, the user needs to head to the GitHub page for Context 7, copy the MCP server code, and then add it as a global MCP server in Cursor's settings. Once set up, Context 7 will automatically start indexing and providing up-to-date documentation.

What is the significance of the Context 7 tool in terms of documentation versioning?

Context 7 is expected to add documentation versioning in the future, which will allow developers to request specific versions of documentation. This is useful for working with legacy code or when older versions of a library are needed.

Why does the user prefer using Context 7 over Cursor’s documentation indexing?

The user prefers Context 7 because it provides more accurate, up-to-date, and relevant code examples, eliminating issues like outdated models or hallucinated code that Cursor sometimes generates. Context 7 ensures that the latest documentation is always accessible.

What is the main takeaway about using Context 7 with Cursor?

The main takeaway is that Context 7 offers a better solution for developers dealing with outdated documentation in Cursor. By providing real-time access to accurate, concise code examples from official documentation, it significantly improves the coding process and avoids the frustration of dealing with old or irrelevant examples.
