Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.

This guide explains the easiest and most robust way to connect your Notion account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

What is Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Notion with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Notion

Ask your agent to connect to Notion, or simply request any Notion-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Notion connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

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.

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.

Way Forward

With Notion connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.

From here, you can extend Hermes further:

  • Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
  • Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
  • Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

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 Hermes?

Yes, you can. Hermes 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.
