# Keys, connections and MCP

Bring in outside services: store keys, authorize accounts, add MCP tools.

Keys

Settings → Keys stores keys for outside services (like Perplexity). Local functions read them when needed; nothing goes into code.

- Stored only on this computer, never uploaded;
- The assistant can't read the values;
- When a feature is missing a key, it says "add XXX in Settings → Keys" with a button to go there.

[![Settings → Keys](https://fsu.creght.com/site/2103669300995821568/1791356051468__annulo_help_settings_keys.png?w=3072&fmt=webp)](https://fsu.creght.com/site/2103669300995821568/1791356051468__annulo_help_settings_keys.png) Settings → Keys

**Don't paste keys into the chat.**

Connections

Settings → Connections authorizes outside accounts; the authorization stays on this computer:

- **Google**: Search Console and GA4 (read-only), multiple accounts supported;
- **creght**: see [Connect creght: cloud and phone](/en/help/creght.md).

[![Settings → Connections](https://fsu.creght.com/site/2103669300995821568/1791356050894__annulo_help_settings_connections.png?w=3072&fmt=webp)](https://fsu.creght.com/site/2103669300995821568/1791356050894__annulo_help_settings_connections.png) Settings → Connections

MCP

Settings → MCP adds outside tools for the assistant and local functions, like Notion or a browser. Click "Add MCP server"; Notion connects in one click. The config format is the same as Claude Code / Cursor, so you can paste yours in. Each server's tools can be toggled: tool definitions go with every request, so turning off unused ones saves context and cost.

[![Settings → MCP → Add MCP server: Notion and a browser in one click, or your own](https://fsu.creght.com/site/2103669300995821568/1791356052082__annulo_help_settings_mcp.png?w=3072&fmt=webp)](https://fsu.creght.com/site/2103669300995821568/1791356052082__annulo_help_settings_mcp.png) Settings → MCP → Add MCP server: Notion and a browser in one click, or your own

From the command line:

```
annulo mcp add notion https://mcp.notion.com/mcp
annulo mcp add files -- npx -y @modelcontextprotocol/server-filesystem ~/Documents
