I spent the long weekend pushing Logic Apps MCP server capabilities further than I had before — and hit two bugs worth documenting. Both are filed. If you're building in this space, save yourself the debugging time. If you've been following along, the MCP server and BODMAS Agent are covered in the previous posts. This post is just about what broke when I wired them together. The Agent Loop fails w
The first time I implemented Vamana from the DiskANN paper, my approximate nearest neighbor index was slower than brute force. On tiny test fixtures, brute force took 0.27 ms per query. My Vamana implementation took 22.98 ms. That sounds absurd. ANN exists to skip work. The problem was not the algorithm. It was how I mapped the paper's abstractions to actual data structures. The DiskANN pseudocode
