# List the GTM APIs

Returns the GTM APIs on Datacircle's sheet, each with how many plans and providers it has.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings.

```json
{ "mcpServers": { "datacircle": { "url": "https://api.datacircle.dev/mcp" } } }
```

Call the MCP tool `list_apis`.

Server URL: https://api.datacircle.dev/mcp

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.
