Re:Launch HN: Pomerado (YC F26) – Turn any website into an MCP for agents

How do you handle credentials and sessions for sites behind a login, like the bank and insurance portals you mention? Is the user's password or session cookie stored on your side, or does the generated MCP run against a session the user keeps locally?
Related: page content is untrusted input that now flows straight into an agent's context. Do the deterministic tools return only structured fields you've extracted, or can arbitrary page text (reviews, messages, product descriptions) pass through? That seems like the main prompt-injection surface for anything that can also perform actions like checkout.
