dsh-notion-plugin

Use Notion from DeepSeek Harness (DSH): a hosted MCP connection, 12 Notion Cookbook skills, and a settings page for multiple workspaces.

A DSH port of Notion's official claude-code-notion-plugin.

What you get

• Notion MCP tools — search, read, create, and edit pages and databases via Notion's hosted MCP server (https://mcp.notion.com/mcp).
• 12 skills — e.g. notion-database-designer, notion-meeting-intelligence, notion-research-documentation, notion-knowledge-capture.
• Multi-workspace — connect several workspaces; one is active at a time. The agent can list and switch with notion_list_workspaces / notion_use_workspace.
• notion_open_page — open a result in the desktop right-sidebar browser (or a new tab elsewhere).
• notion_current_page — return the URL and page id of the page open in the sidebar browser, so the agent can answer "what does this page say?" by reading it. Reflects pages opened through Notion tools.

There are no slash commands: DSH runs commands locally without sending them to the model, so the skills plus natural language replace them.

Install

Install this directory as a DSH bundle (plugin_manager → install_bundle, target = this folder). It is not published to a registry.

Connect a workspace

Open the plugin's Settings page and press Connect. The plugin runs Notion's OAuth (dynamic client registration + PKCE) on a local callback (http://localhost:53682/callback) and forwards MCP traffic through a local proxy (http://localhost:53683/mcp) that injects and refreshes the token for the active account. Use Open Notion to sign in once in the sidebar browser.

A Notion "login" connection created in the Notion UI is not a valid MCP client — only dynamically registered clients are accepted.

Known limitation

The desktop sidebar browser uses a non-persistent session, so you sign in to Notion again after each app restart. Persistent login would need the host to use a persist: session partition.
