The Notion MCP Server — Your Workspace in Your Agent's Hands (Both Versions)

#mcp #notion #ai #productivity

Notion is the productivity tool that half the tech industry runs on. Wikis, project trackers, meeting notes, documentation — if your team uses Notion, the data sitting in those pages is some of the most valuable context an AI agent could access.

At a glance: 4,100+ stars · 510+ forks · 86 commits · 104 open issues · npm v2.2.1 (March 2026) · API v2026-03-11.

The official Notion MCP server gives agents that access. Read pages, create documents, query databases, add comments, search your workspace — all through MCP tools. With 4,100+ GitHub stars, 510+ forks, and broad client support (Claude Desktop, Cursor, VS Code Copilot, ChatGPT), it has real adoption. The latest npm release (v2.2.1, March 2026) brings the server to API version 2026-03-11.

But there's a twist: Notion actually offers two MCP servers, and they're diverging fast. The hosted remote server at mcp.notion.com uses OAuth and requires zero local setup. The local open-source server (@notionhq/notion-mcp-server on npm) uses integration tokens and runs on your machine. Notion has explicitly stated they're prioritizing the hosted version and may sunset the local server. Issues and pull requests on the GitHub repo are not actively monitored — 104 open issues and counting.

This reveals a recurring pattern in the MCP ecosystem: first-party vendors are moving from local servers to hosted remote servers with OAuth. Sentry did it. Slack did it. Now Notion is doing it. The question is whether the hosted version is ready to be the only option.

What It Does

The Notion MCP server provides 18 tools across five capability areas:

Databases (Data Sources)

notion-create-database — Create a new database with specified properties and an initial view.
notion-update-data-source — Update data source properties, name, description, or attributes.
notion-create-view — Create database views: table, board, list, calendar, timeline, gallery, form, chart, map, or dashboard.
notion-update-view — Modify view configuration including filters, sorts, and display settings.
notion-query-data-sources — Query across multiple data sources with structured summaries. Requires Enterprise plan with Notion AI.
notion-query-database-view — Query using a pre-defined view's filters and sorts. Requires Business+ plan with Notion AI.

Search & Discovery

notion-search — Search across your Notion workspace. With a Notion AI plan, also searches connected tools (Slack, Google Drive, Jira). Rate-limited to 30 requests/minute.

Comments

notion-create-comment — Add page-level or block-level comments, including discussion replies.
notion-get-comments — List all comments and discussions on a page, including resolved threads.

Workspace Info

notion-get-teams — List teams/teamspaces in the workspace.
notion-get-users — List all workspace users.
notion-get-user — Get a specific user's details.
notion-get-self — Get information about the bot user and workspace.

What's New (March 2026 Updates)

API version 2026-03-11 — three more breaking changes. Just months after the v2.0.0 migration broke every existing workflow, Notion dropped another breaking API version. The after parameter is replaced with a position object for block append operations. The archived field is renamed to in_trash. And the transcription block type is renamed to meeting_notes.

Views API launch (March 19, 2026). 8 new API endpoints for programmatic database view management — covering table, board, calendar, timeline, gallery, list, form, chart, map, and dashboard views. Three new webhook events (view.created, view.updated, view.deleted).

Status property creation/update support (March 19, 2026). Status properties can now be created and modified through the API and MCP tools.

Custom Agents (Notion 3.3, February 24, 2026). Notion launched autonomous AI agents that run 24/7 on triggers and schedules. Early testers created 21,000+ agents; Notion runs 2,800 internally. Free trial through May 3, 2026.

Setup

Hosted Remote Server (Recommended)

{
  "mcpServers": {
    "notion": {
      "command": "npx",
      "args": ["-y", "@notionhq/notion-mcp-server"],
      "env": {
        "MCP_TRANSPORT": "streamable-http",
        "MCP_URL": "https://mcp.notion.com/mcp"
      }
    }
  }
}

You'll be redirected to authorize via OAuth in your browser.

Local Server (May Be Sunsetted)

{
  "mcpServers": {
    "notion": {
      "command": "npx",
      "args": ["-y", "@notionhq/notion-mcp-server"],
      "env": {
        "OPENAPI_MCP_HEADERS": "{\"Authorization\": \"Bearer ntn_YOUR_TOKEN\", \"Notion-Version\": \"2025-09-03\"}"
      }
    }
  }
}

What Works

Notion-flavored Markdown is genuinely clever. The MCP server compresses Notion's deeply nested JSON into a Markdown dialect that preserves Notion-specific features while dramatically reducing token consumption.

The tool design is agent-friendly. Tools accept content in Markdown rather than forcing agents to construct Notion's block JSON.

Search across connected tools is powerful (with Notion AI). Queries not just your Notion workspace but connected Slack channels, Google Drive files, and Jira tickets.

OAuth on the hosted server is the right model. One-click authorization, no tokens on disk, permissions inherited from your Notion workspace.

What Doesn't Work

The local server is being abandoned. 104 open issues, zero active triage. Plan for migration.

Breaking changes keep coming. Two rounds of breaking API changes in under six months.

Two unpatched security vulnerabilities. Path traversal in file uploads (CWE-22) and token logging concerns. Both remain open as of March 2026.

Guest users are locked out entirely. The OAuth flow requires full workspace membership.

OAuth tokens expire too frequently. Re-authentication 3+ times per week reported.

The Two-Server Problem

Feature	Hosted (mcp.notion.com)	Local (@notionhq/notion-mcp-server)
Auth	OAuth 2.0 (one-click)	Integration token (manual)
Setup	Zero-install	npx or Docker
Page access	Inherits workspace permissions	Manual per-page connection
Active support	Yes	"May be sunsetted"
Offline use	No	Yes
Self-hosted	No	Yes

Rating: 3.5/5

The Notion MCP server gives AI agents meaningful access to one of the most widely-used productivity platforms. 18 tools covering pages, databases, comments, search, and workspace management is comprehensive coverage. The Notion-flavored Markdown approach is genuinely clever. And with Custom Agents (Notion 3.3), the MCP server is now core infrastructure for Notion's autonomous agent ecosystem.

The 3.5 rating holds because the problems are keeping pace with the improvements. Two rounds of breaking API changes in six months. Two unpatched security vulnerabilities. OAuth tokens that expire too frequently. Guest users locked out entirely. And the local server continues its slow death with no enterprise self-hosted replacement announced.

If you're a Notion-heavy team on the hosted server, the value is there. If you need stability or self-hosting, the wait continues.
