# Available resources

> Atlas MCP resources you can open again after a search or research run.

## 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`:

| Resource template                         | What it returns                                       |
| ----------------------------------------- | ----------------------------------------------------- |
| `atlas://discovery-runs/{run_id}`         | Full structured discovery-run record                  |
| `atlas://discovery-runs/{run_id}/brief`   | Markdown research brief with leads, sources, and gaps |
| `atlas://discovery-runs/{run_id}/sources` | Sources referenced by a discovery-run summary         |
| `atlas://entities/{entity_id}/sources`    | Public source trail for one known entity              |
| `atlas://cities/{place_key}/coverage`     | Coverage summary for one city, such as `gary-in`      |
| `atlas://states/{state}/coverage`         | Coverage summary for one state, such as `IN`          |

## 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.
