Agents and agentic workflows need structured signals, not just raw pages. Existence Compiler turns a URL into a structured diagnostic object an agent can read, compare, and use to decide what to investigate next.
A raw HTML page forces every agent to re-derive the same signals: whether the site can be discovered, whether it states its purpose, whether it has metadata, schema, feeds, or trust signals. Existence Compiler does that work once and returns a consistent, deterministic object.
A single analyze_url call returns a Digital Existence Score, the dimension breakdown, key signals, prioritized actions, and standalone diagnostic surfaces: AI & Search Visibility, Google AI & Agentic Search Readiness, Security / Trust, and a Backend Consistency summary. The analysis is structural and does not execute the site's JavaScript.
Programmatic access is over MCP at /api/mcp, with a bearer token and fail-closed behavior in production. The /mcp page documents the tools, the auth model, and the output shape.
