# Atria

> Atria is a hosted MCP server for US site diligence. An agent connected to it can look up a parcel from an address, coordinate or assessor parcel number, and screen the site for power, gas, water, flood, zoning rules, terrain, hazards, environmental records and more. Every value comes from public records and comes back with its source and the time it was fetched.

## Connect

- MCP server URL: https://askatria.ai/mcp (streamable HTTP)
- Authentication: OAuth 2.1 with PKCE and dynamic client registration. An MCP client discovers it from the 401 response and https://askatria.ai/.well-known/oauth-protected-resource/mcp; the authorization server metadata is at https://askatria.ai/.well-known/oauth-authorization-server.
- Signing up: connecting for the first time opens Atria's consent screen. A person without an account can create one there with Google or an email address, and returns to the consent screen to approve the connection.

## Pricing

- A new account starts on the Free plan: 5,000 credits a month, no card needed.
