# List content gaps

Lists the tracked prompts where AI answer engines mention competitors but not the brand, with the engines, the competitors and an opportunity score.

Note: Needs a GEO plan or AI credits. Get the project id from `list_projects` (`notra geo projects list`) first. A gap's `id` is what a content brief takes as `sourceId`, with `sourceKind` set to `gap`.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "notra": { "url": "https://mcp.usenotra.com/mcp" } } }
```

Call the MCP tool `list_geo_content_gaps`.

Server URL: https://mcp.usenotra.com/mcp

### CLI (official)

Install the command and sign in with it, then confirm it runs.

```sh
npm i -g notra
notra --version
```

Run `notra geo gaps list`.

### API (official)

- Base URL: https://api.usenotra.com
- Endpoint: `GET /v1/projects/{projectId}/geo/gaps`
- Auth: send the header `Authorization: Bearer $NOTRA_API_KEY`
- Docs: https://docs.usenotra.com/api/authentication

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
