Introduction

Manage your Notion directly from Claude Code with zero worries about OAuth hassles, API-breaking issues, or reliability and security concerns.

You can do this in two different ways:

  1. Via Rube - Direct and easiest approach
  2. Via Composio SDK - Programmatic approach with more control

Why Rube?

Rube is a universal MCP server with access to 850+ SaaS apps. It ensures just-in-time tool loading so Claude can access the tools it needs, a remote workbench for programmatic tool calling and handling large tool responses out of the LLM context window, ensuring the LLM context window remains clean.

Connect Notion to Claude Code with Rube

1. Get the MCP URL

Copy and paste the below command in Claude Code to add Rube MCP.

Terminal

2. Authenticate Rube

Run /mcp to view Rube

bash
/mcp
Run /mcp to view Rube in Claude Code
Click on Rube to authenticate
Authentication flow complete

3. Ensure it's connected

Run /mcp again to verify the connection. Now, do whatever you want with Claude Code and Notion.

Supported Tools & Triggers

Tools
Triggers
Add multiple content blocks (bulk, user-friendly)Efficiently adds multiple standard content blocks to a notion page in a single api call with automatic markdown parsing.
Append complex blocks (advanced, full control)Appends complex blocks with full notion block structure to a parent block or page.
Archive Notion PageArchives (moves to trash) or unarchives (restores from trash) a specified notion page.
Create commentAdds a comment to a notion page (via `parent page id`) or to an existing discussion thread (via `discussion id`); cannot create new discussion threads on specific blocks (inline comments).
Create Notion DatabaseCreates a new notion database as a subpage under a specified parent page with a defined properties schema; use this action exclusively for creating new databases.
Create Notion pageCreates a new empty page in a notion workspace.
Delete a blockArchives a notion block, page, or database using its id, which sets its 'archived' property to true (like moving to "trash" in the ui) and allows it to be restored later.
Duplicate pageDuplicates a notion page, including all its content, properties, and nested blocks, under a specified parent page or workspace.
Fetch Notion Block ChildrenRetrieves a paginated list of direct, first-level child block objects along with contents for a given parent notion block or page id; use block ids from the response for subsequent calls to access deeply nested content.
Fetch Notion block metadataFetches metadata for a notion block (or page, as pages are blocks) using its valid uuid; if the block has children, use fetch block contents to fetch their contents.
Fetch commentsFetches unresolved comments for a specified notion block or page id.
Fetch Notion DataFetches notion items (pages and/or databases) from the notion workspace, use this to get minimal data about the items in the workspace with a query or list all items in the workspace with minimal data
Fetch DatabaseFetches a notion database's structural metadata (properties, title, etc.
Fetch database rowRetrieves a notion database row's properties and metadata; use fetch block contents for page content blocks.
Get About MeRetrieves the user object for the bot associated with the current notion integration token, typically to obtain the bot's user id for other api operations.
Get about userRetrieves detailed information about a specific notion user, such as their name, avatar, and email, based on their unique user id.
Get page propertyCall this to get a specific property from a notion page when you have a valid `page id` and `property id`; handles pagination for properties returning multiple items.
Insert row databaseCreates a new page (row) in a specified notion database.
List usersRetrieves a paginated list of users (excluding guests) from the notion workspace; the number of users returned per page may be less than the requested `page size`.
Query databaseQueries a notion database for pages (rows), where rows are pages and columns are properties; ensure sort property names correspond to existing database properties.
Retrieve CommentTool to retrieve a specific comment by its id.
Retrieve Database PropertyTool to retrieve a specific property object of a notion database.
Search Notion pageSearches notion pages and databases by title; an empty query lists all accessible items, useful for discovering ids or as a fallback when a specific query yields no results.
Update blockUpdates an existing notion block's textual content or type-specific properties (e.
Update PageTool to update the properties, icon, cover, or archive status of a page.
Update row databaseUpdates or archives an existing notion database row (page) using its `row id`, allowing modification of its icon, cover, and/or properties; ensure the target page is accessible and property details (names/ids and values) align with the database schema and specified formats.
Update database schemaUpdates an existing notion database's title, description, and/or properties; at least one of these attributes must be provided to effect a change.

What is the Notion MCP server, and what's possible with it?

The Notion MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Notion account. It provides structured and secure access to your notes, docs, wikis, and tasks, so your agent can perform actions like creating pages, managing databases, adding content, commenting, and organizing your Notion workspace for you.

  • Bulk content creation and formatting: Let your agent efficiently add and format multiple blocks of text, lists, or markdown content to Notion pages in one go.
  • Automated page and database management: Have your agent create new pages, duplicate existing ones, or set up entire databases with custom properties—no manual setup required.
  • Smart commenting and collaboration: Enable your agent to add comments to pages or discussion threads, making real-time collaboration smoother.
  • Workspace organization and cleanup: Ask your agent to archive, delete, or restore pages and blocks, keeping your workspace tidy and up to date.
  • Deep block and structure retrieval: Direct your agent to fetch metadata, list child blocks, or dig into nested content for analysis, reporting, or workflow automation.

Connecting Notion via Tool Router

Tool Router is the underlying tech that powers Rube. It's a universal gateway that does everything Rube does but with much more programmatic control. You can programmatically generate an MCP URL with the app you need (here Notion) for even more tool search precision. It's secure and reliable.

How the Tool Router works

The Tool Router follows a three-phase workflow:

  1. Discovery: Searches for tools matching your task and returns relevant toolkits with their details.
  2. Authentication: Checks for active connections. If missing, creates an auth config and returns a connection URL via Auth Link.
  3. Execution: Executes the action using the authenticated connection.

Step-by-step Guide

Prerequisites

Before starting, make sure you have:
  • Claude Pro, Max, or API billing enabled Anthropic account
  • Composio API Key
  • A Notion account
  • Basic knowledge of Python or TypeScript

Install Claude Code

bash
# macOS, Linux, WSL
curl -fsSL https://claude.ai/install.sh | bash

# Windows PowerShell
irm https://claude.ai/install.ps1 | iex

# Windows CMD
curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd

To install Claude Code, use one of the following methods based on your operating system:

Set up Claude Code

bash
cd your-project-folder
claude

Open a terminal, go to your project folder, and start Claude Code:

  • Claude Code will open in your terminal
  • Follow the prompts to sign in with your Anthropic account
  • Complete the authentication flow
  • Once authenticated, you can start using Claude Code
Claude Code initial setup showing sign-in prompt
Claude Code terminal after successful login

Set up environment variables

bash
COMPOSIO_API_KEY=your_composio_api_key_here
USER_ID=your_user_id_here

Create a .env file in your project root with the following variables:

  • COMPOSIO_API_KEY authenticates with Composio (get it from Composio dashboard)
  • USER_ID identifies the user for session management (use any unique identifier)

Install Composio library

pip install composio-core python-dotenv

Install the Composio Python library to create MCP sessions.

  • composio-core provides the core Composio functionality
  • python-dotenv loads environment variables from your .env file

Generate Composio MCP URL

import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
USER_ID = os.getenv("USER_ID")

composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=USER_ID,
    toolkits=["notion"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url

print(f"MCP URL: {COMPOSIO_MCP_URL}")
print(f"\nUse this command to add to Claude Code:")
print(f'claude mcp add --transport http notion-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"')

Create a script to generate a Composio MCP URL for Notion. This URL will be used to connect Claude Code to Notion.

What's happening:
  • We import the Composio client and load environment variables
  • Create a Composio instance with your API key
  • Call create() to create a Tool Router session for Notion
  • The returned mcp.url is the MCP server URL that Claude Code will use
  • The script prints this URL so you can copy it

Run the script and copy the MCP URL

python generate_mcp_url.py

Run your Python script to generate the MCP URL.

  • The script connects to Composio and creates a Tool Router session
  • It prints the MCP URL and the exact command you need to run
  • Copy the entire claude mcp add command from the output

Add Notion MCP to Claude Code

bash
claude mcp add --transport http notion-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY"

# Then restart Claude Code
exit
claude

In your terminal, add the MCP server using the command from the previous step. The command format is:

  • claude mcp add registers a new MCP server with Claude Code
  • --transport http specifies that this is an HTTP-based MCP server
  • The server name (notion-composio) is how you'll reference it
  • The URL points to your Composio Tool Router session
  • --headers includes your Composio API key for authentication

After running the command, close the current Claude Code session and start a new one for the changes to take effect.

Verify the installation

bash
claude mcp list

Check that your Notion MCP server is properly configured.

  • This command lists all MCP servers registered with Claude Code
  • You should see your notion-composio entry in the list
  • This confirms that Claude Code can now access Notion tools

If everything is wired up, you should see your notion-composio entry listed:

Claude Code MCP list showing the toolkit MCP server

Authenticate Notion

The first time you try to use Notion tools, you'll be prompted to authenticate.

  • Claude Code will detect that you need to authenticate with Notion
  • It will show you an authentication link
  • Open the link in your browser (or copy/paste it)
  • Complete the Notion authorization flow
  • Return to the terminal and start using Notion through Claude Code

Once authenticated, you can ask Claude Code to perform Notion operations in natural language. For example:

  • "Add meeting notes to project wiki page"
  • "Create a new task database for Q3"
  • "Archive completed sprint summary pages"

Complete Code

Here's the complete code to get you started with Notion and Claude Code:

import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY")
USER_ID = os.getenv("USER_ID")

composio_client = Composio(api_key=COMPOSIO_API_KEY)

composio_session = composio_client.create(
    user_id=USER_ID,
    toolkits=["notion"],
)

COMPOSIO_MCP_URL = composio_session.mcp.url

print(f"MCP URL: {COMPOSIO_MCP_URL}")
print(f"\nUse this command to add to Claude Code:")
print(f'claude mcp add --transport http notion-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"')

Conclusion

You've successfully integrated Notion with Claude Code using Composio's MCP server. Now you can interact with Notion directly from your terminal using natural language commands.

Key features of this setup:

  • Terminal-native experience without switching contexts
  • Natural language commands for Notion operations
  • Secure authentication through Composio's managed MCP
  • Tool Router for dynamic tool discovery and execution

Next steps:

  • Try asking Claude Code to perform various Notion operations
  • Add more toolkits to your Tool Router session for multi-app workflows
  • Integrate this setup into your development workflow for increased productivity

You can extend this by adding more toolkits, implementing custom workflows, or building automation scripts that leverage Claude Code's capabilities.

FAQ

What are the differences in Tool Router MCP and Notion MCP?

With a standalone Notion MCP server, the agents and LLMs can only access a fixed set of Notion tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Notion and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Claude Code?

Yes, you can. Claude Code fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Notion tools.

Can I manage the permissions and scopes for Notion while using Tool Router?

Yes, absolutely. You can configure which Notion scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Notion data and credentials are handled as safely as possible.
