    • Cursor Looking at Git PR - Discussion - Cursor - Community Forum CursorAI/Forum

      • I was looking for the same thing and was bout to build a pipeline for PR review, but that is actually not necessary. In Cursor Chat, you can use @PR to reference it and add some instructions that serve your needs.
        Here’s how I do it:
        

        • @PR (Diff with Main Branch) 
          Please analyze the code changes and provide the following information:
          
          1. **Intent and Purpose**: Summarize the goal of the changes. Explain what functionality or behavior the changes aim to introduce, modify, or fix.
          
          2. **Potential Issues**: Identify any possible problems the changes might introduce, such as:
             - Bugs or unintended side effects.
             - Performance concerns.
             - Code quality issues (e.g., readability, maintainability, scalability).
             - Violations of best practices or standards.
          
          3. **Suggestions for Improvement**: Recommend any improvements or alternative approaches that could enhance the code.

          • In the course of your prompting, you could ask for things like "look up the docs for ....", "query this sqlite db for...", "create this table..." so on and so forth. The sky is the limit really.
            

          • The LLM should figure out it wants to call a tool, and format a response appropriately. Cursor(I believe) is providing the model a system prompt so it understands how to do this. The response is handed back to the LLM and then it decides how to present it to you, but the actual interactions should also be visible.
            

          • For me, I can ask it to look at files I don't have open in Cursor using the filesystem server, or query the perplexity API to search the web for updated docs info using mcp-perplexity, etc etc.

          • Kind of? The context length doesn't change but Cursor can more easily check files on your computer even if it's out of context.
            

          • Just think of MCP servers as a library of tools that you can install. Cursor comes with tools for say, running CLI commands built in. You just have access to a collection of pre-built ones.
            

        • comment by badasimo

          • It also has a security benefit. Cursor can already interact with things sort of... raw. You can let it SSH into a remote server for instance or run commands on your computer. An MCP will have a defined set of things it can and can't do and interact with and have it formatted better for interacting with an LLM.
            

          • For instance many command line tools have styling and decoration, interactive features etc that an LLM doesn't need, it just needs output. Lately agent has struggled with things like that.
            

          • I believe that we will have other agents/models inside MCPs doing their own special things. For instance operating browsers and things like that.

      • deepdoctection/deepdoctection: A Repo For Document AI
        • deepdoctection is a Python library that orchestrates document extraction and document layout analysis tasks using deep learning models. It does not implement models but enables you to build pipelines using highly acknowledged libraries for object detection, OCR and selected NLP tasks and provides an integrated framework for fine-tuning, evaluating and running models. For more specific text processing tasks use one of the many other great NLP libraries.
        • deepdoctection focuses on applications and is made for those who want to solve real world problems related to document extraction from PDFs or scans in various image formats.

        • recently updated (9 hours ago)
        • Marker converts PDFs and images to markdown, JSON, and HTML quickly and accurately.
        • Marker is a pipeline of deep learning models:
          • Extract text, OCR if necessary (heuristics, surya)
          • Detect page layout and find reading order (surya)
          • Clean and format each block (heuristics, texify, surya)
          • Optionally use an LLM to improve quality
          • Combine blocks and postprocess complete text
        • It only uses models where necessary, which improves speed and accuracy.

      • The "find implementation" feature doesn't seem to work well. I have a method f in a class A that inherits from B and reimplements f, and I'd like to list all "f" implementation, but nothing gets listed.
      • Is the feature included in Pylance, and if yes, am I missing something?
      • We don't implement the go-to or find implementation calls, so this would be an enhancement.
      • Moving this issue to discussion as an enhancement request for comments and upvotes.
      • For someone like me coming from IntelliJ Idea/PyCharm, missing this features feels like a real degradation of productivity. We have a massive codebase with thousands of files and hundreds of class hierarchies.
      • Now that type hierarchy has been added (#4978 - thanks!), does it make sense to also support "Find All Implementations"?
      • I find a solution. Use "Show Type Hierarchy" to find implementation methods and "Show Calls Hierarchy" to find methods in parent classes.
