Our own EVP, Chief Scientist & Head of Enterprise AI Prem Natarajan recently spoke to TechTarget about Capital One’s partnership with the National Science Foundation (NSF), which will help launch five new National AI Research Institutes to drive breakthroughs in high-impact areas across society like material and computational sciences, economics, and mental health. https://bit.ly/4grWY3m

MCP - a open protocol for AI (LLM) to talk to other tools / systems / applications. Naive, but don’t judge me, I was judging AI capabilities with me being Naive   - So I asked Claude AI to create an MCP - An MCP the AI itself will use - Gave a website address to which MCP had to be created (with public APIs) - It Generated extensive, detailed code - I dwelled on it, fine tuned for my preference / requirements, it went ahead and did a bit more than I asked for. Website was analysed in minutes (amusing and scary) - I asked it to package it as executable package - I had configured file system MCP - So, Claude leveraged that and created a python project in filesystem and created Project with proper files and folder structure - Here comes Claude code (CC) - This python project of MCP server, was not in a running state - Asked CC to make the code runnable (of course I was in control (manual loop) of the changes it was making) - MCP server to run in local system (MacOs) needed some changes in trivial python code, CC made the changes - Interesting side part, during this whole process, it was also creating documentation, to install server, to run server and the MCP config for other tools - At times I had to say update the documentation - OOPS !! Code got changed, but what was changed ? - I asked CC to make this project version controlled. Oh my Devaa (God), it converted the project into a Git repo (local) - Created git related files, Auto committed all files. All I had to do was, say yes, go ahead - Well, we got side tracked, lets get back to MCP - So, now I asked CC to run the server (lazy to copy the command and run it in next tab terminal) - Obviously.. It had issues, and obviously it auto corrected the code - It wrote test cases, wrote test start script, tested it, committed the code and then - now it tells me, 'All fixed, Want to run?', Howdhu maga howdhu, run (yes dude yes, run) - MCP server started. I updated MCP configuration and restarted Claude Desktop - pssssttt….. curios? - :( Error: MCP server couldn’t be started - Again me being extremely (purposefully) lazy, told CC, you are being dumb, fix the startup error - I guess, I hurt its Ego. - It asked permissions for MCP server log file. whaaaat really ?, it wants to read log files now, wow. - It test ran with its test scripts, read the log, analysed like a nerd, updated the test files and code, reran until it was fixed and updated the documentation and also committed the code - What can I say, I was watching Christopher Nolan movie level events. - Finally, MCP worked, I tested few things, results were as expected.   It ain’t over, my architectural / Engineering hormones kicked in. How about containerisation ? How about productionising it ? How about Security & Authentication ? How about Performance & Scalability ? How about Operational Readiness ? How about AI Security, Gaurdrails ? Stay tuned, I will be back 🙂

Most systems do not break from load. They break from misunderstanding. It is not pressure that kills architecture. It is the lack of Air. Example 1: A partner asked us to copy their customer category as a simple flag. Looked easy. Turned into chaos. Flags drifted. Values mismatched. Nobody knew what the flag meant. One question changed everything: “What outcome does this category drive?” Suddenly the truth appeared. We did not need their flag at all. We needed the behaviour behind it. Once context moved, the whole design became light. Example 2: A team passed a “specialHandling = true” flag. Simple, right? Except no one knew what “special” meant. The receiving domain did not want the flag. They wanted the treatment. Flags carry data. Air carries intent. And intent is what keeps systems breathable. The lightest architectures are the ones where context moves faster than requirements.

Microservices can expose weak architecture in brutal detail. In a digital bank, that impact shows up in customer experience, reporting, and regulator conversations before it shows up in cloud bills. Here is a quick lens before creating the next service: Start with domains: If KYC, onboarding, payments, and collections are fuzzy on the whiteboard, they will be chaos in production. Raise the bar on operations: Logging, tracing, runtime configuration, and on call discipline are prerequisites, not nice to have. Anchor on outcomes: Measure success in safer changes, faster launches, and smoother audits, not in the number of services. What is one architectural decision in your organization that quietly made everything easier, or much harder? #Microservices #SoftwareArchitecture #EnterpriseArchitecture #DigitalBanking #EngineeringLeadership #TechStrategy #SystemDesign #PlatformEngineering #DistributedSystems

As we navigate this AI paradigm shift, it's vital to stay grounded in our core principles as we rethink everything about the user experience. Excited to speak at the Open Source in Finance Forum New York about how the "Connective Tissue of Financial Services" now extends into creating interoperability for our ecosystem of AI capabilities. #FINOS #AI #OpenSource #Finance #Interoperability #AgenticAI #OSFF2025
