How to connect to the Notion MCP with Claude Code (4 steps)

With Merge Agent Handler's Notion MCP server connected to Claude Code, your agents can search pages, create and update content, and manage databases directly from the terminal.                                                                                                              

This guide walks through connecting Claude Code to Notion via Merge Agent Handler in five steps.                                                                                                                   

How it works

Merge Agent Handler acts as the layer between Claude Code and Notion's API. You install the Merge CLI, authenticate once, and register the connection with a single command. Agent Handler manages your Notion OAuth credentials and routes every API call so you don't store tokens locally or handle credential state yourself.

Here's the command that registers the connection:

merge setup claude-code

Prerequisites

Before getting started, you'll need the following:

• A Merge Agent Handler account
• Claude Code installed (run claude --version to confirm)
• pipx installed (run pipx --version to confirm, or install via pip install pipx)
• A Notion account with appropriate workspace permissions

If you want to connect Merge Agent Handler's Notion MCP with internal or customer-facing agentic products, you can follow the steps in our docs.

1. Install the Merge CLI

Install with pipx: pipx install merge-api

Verify your installation: merge --version

2. Configure the CLI and log in

Authenticate the CLI with your Merge Agent Handler account: merge login

Once complete, the CLI can make authorized API requests on your behalf.

3. Add Agent Handler to Claude Code

To add Agent Handler to Claude Code, run:

merge setup claude-code

Or register manually with:

claude mcp add 
--transport http agent-handler https://ah-api.merge.dev/mcp

Verify the connection registered. Open Claude Code and run: /mcp

agent-handler should appear under Local MCPs with a connected status.

4. Authenticate Notion

Select agent-handler from the MCP list. This opens a browser window where you select which integrations to authenticate. Choose Notion and complete the OAuth flow, granting your agent access to the pages and databases you specify.

The first time you use a Notion tool in a Claude Code session, a Magic Link may appear to complete connector authentication. Once authenticated, Merge stores and manages the token. You won't need to re-authenticate unless you revoke access.

You can now prompt Claude Code to take action in Notion. For example: "Search the engineering wiki for any existing documentation on our authentication service before I start writing the new spec."

Or you can ask Claude Code for information in Notion: "What’s the top priority for our product roadmap next quarter?”
