Description

Hi HN! We built Zalor. It turns an OpenAPI spec into an MCP server, so you can make your APIs callable by Claude or ChatGPT without writing any code. Here's a list of specs you can try: https://github.com/ZalorAI/test-data/tree/main/openapi, but feel free to use your own.For background, MCP is a protocol that standardizes how you connect tools to AI assistants. We're both engineers at large software companies, and when we worked on MCP integrations we saw how long setup took and how often the spec was changing. So we built a platform to handle the MCP infrastructure, letting you keep doing normal API work and expose it to AI when you're ready.Right now we're creating a 1:1 mapping from APIs to MCP tools, but we're working on improving tool discovery so the AI doesn't get overwhelmed by 100 endpoints at the start of every conversation.Still early. Would love feedback!
