Overview

Atlas resources give compatible clients a stable way to open the same research output again. Ask your assistant to find the record first; when Atlas returns a resource URI, the client can reopen the full record, source trail, coverage summary, or research brief later. resources/list returns only a short set of recent research runs and Atlas UI resources. It does not list every entity, source, place, or run in Atlas.

​
Resource templates

MCP clients can discover these resource patterns through resources/templates/list:

​
How resources are reopened

Atlas operations return resource_uri fields for outputs that can be opened again. For example, a research-run lookup returns atlas://discovery-runs/{run_id}, and place coverage responses return atlas://cities/{place_key}/coverage or atlas://states/{state}/coverage. Pass one of those URIs to resources/read to reopen the same output without repeating the search that found it.

​
Large catalogs

Entity resources appear after a search or lookup returns an entity ID. They are not included in resources/list. Use search_entities, get_place_entities, or list_discovery_runs to find the relevant record first, then read the returned resource_uri later.
