Rindler is a Y Combinator (Summer 2026) company that operates a hosted Model Context Protocol (MCP) server turning any pre-onboarded website — including sites that have no API — into a deterministic, typed set of tools that AI agents can reliably use. Agents open a session against a mapped site, dispatch a semantic action (search, add to cart, submit a form, move a candidate, pull a statement), and receive structured JSON records instead of raw HTML, accessibility trees, or DOM selectors. Rindler handles authentication, 2FA, pop-ups, bot defenses, navigation, retries, and error recovery server-side, and re-verifies each site mapping against the real site before shipping it. It targets legacy portals, private SaaS dashboards, government registries, healthcare/insurance portals, ATS systems, and bank/brokerage sites.
