Ask HN: Who is using MCP in production?

A Hacker News thread asks who actually runs MCP in production. One dev built a UK council scraper with Claude, added an MCP interface on a whim, and found Claude autonomously queried it during debugging—surprisingly useful. Another hooked Claude Code to Jira and Figma, calling natural-language Jira a relief but MCP only 'a tiny bit easier' than direct API. A skeptic questioned why a non-editable tool surface beats a readable API client; a defender replied that without MCP, Claude falls back to screenshotting Figma. The post doesn't disclose how widely MCP is deployed in production.
