Everyday use
For developers

Claude

Custom connectors require a paid Claude plan (Pro, Max, Team, or Enterprise). The setup is the same for claude.ai and the Claude Desktop app.

In claude.ai or the Claude Desktop app, open the sidebar, select Customize, and go to the Connectors tab.
Select Add custom connector and fill in the fields: name Natural, remote MCP server URL https://mcp.natural.com.
Select Add, then Connect. Your browser opens Natural’s authorization page; approve it, and you are redirected back to Claude.

ChatGPT

Custom plugins require a paid ChatGPT plan (Plus, Pro, Business, or Enterprise).

Open Settings → Security and turn on Developer mode.
Select Plugins in the sidebar, then the + button, and fill in the fields: name Natural, MCP server URL https://mcp.natural.com, authentication OAuth.
Accept ChatGPT’s unverified-server disclaimer and select Create, then Sign in with Natural. Approve Natural’s authorization page when it opens.

Claude Code

Add Natural’s hosted MCP server and sign in with OAuth. Your browser opens Natural’s authorization page; approve it:
claude mcp add --transport http natural https://mcp.natural.com --scope user && claude mcp login natural
Start a fresh Claude Code session and run /mcp. Confirm natural shows as connected and authenticated. If it’s not, run claude mcp login natural again to re-authorize.

Try it:

Use Natural to check my wallet balance.

Codex CLI

Add Natural as a remote HTTP server, then approve Natural’s authorization page in your browser. If the browser does not open on its own, run codex mcp login natural:
codex mcp add natural --url https://mcp.natural.com
Start a fresh Codex session and run /mcp. Confirm natural shows as connected and authenticated. If it’s not, run codex mcp login natural again to re-authorize.

Try it:

Use Natural to check my wallet balance.

Codex app

Open the Codex app and go to Plugins in the sidebar.
Open the dropdown (⌄) in the top right, select Add marketplace, and paste this into the Source field:
naturalpay/agent-plugins
Switch to Personal and select Install. Your browser opens Natural’s authorization page; approve it.

Cursor

In Cursor, open Settings → Tools & MCPs, select New MCP Server (this opens mcp.json), merge Natural into the config, and save:
{ "mcpServers": { "natural": { "url": "https://mcp.natural.com" } } }
Find Natural under Settings → Tools & MCPs and connect it. Your browser opens Natural’s authorization page; approve it, and you are redirected back to Cursor. If Natural doesn’t appear, restart Cursor.

Try it:

Use Natural to check my wallet balance.

Agent key (API)

For headless or custom agents that can’t sign in with browser OAuth: create an agent and issue a key, then use it as the bearer token against mcp.natural.com or the REST API. See the API-key fallback for details.

Using a host that is not listed? Any MCP-aware host with remote-server OAuth works; see Any other MCP-aware host in the MCP guide, which also covers the CLI OAuth and API-key fallbacks.
