Best for
  • Developers needing integration between Microsoft 365 and AI assistants
  • Individuals wanting natural language control of Outlook and OneDrive
  • Teams automating email and calendar management
  • Teams and individuals who already manage docs/wikis in Notion and want AI clients (Claude Desktop, Cursor, etc.) to operate on that content directly
  • Developers who want to self-host a local MCP server rather than use a remote hosted option
  • Automation/agent workflows that need to query or update Notion database records programmatically
Not for
  • Organizations with strict security requirements against third-party servers
  • Users needing deep integration with Microsoft Teams or SharePoint (not supported)
  • Beginners wanting a plug-and-play solution without Azure configuration
  • Users who want the standard-OAuth, zero-JSON-config install with active official support — Notion recommends its newer remote Notion MCP server for that
  • Users uncomfortable handing a Notion integration token to a locally-run LLM client
  • Use cases needing capabilities the integration deliberately excludes, such as deleting databases
  • Long-term production deployments that need guaranteed maintenance, given this repo may be sunset
Required permissions
  • Microsoft Graph delegated permissions: offline_access, User.Read, Mail.ReadWrite, Mail.Send, Calendars.ReadWrite, Files.ReadWrite
  • Power Automate API scope (optional): https://service.flow.microsoft.com//.default
  • Local file system: tokens stored in ~/.outlook-mcp-tokens.json
  • A Notion internal integration token (NOTION_TOKEN or the Authorization value in OPENAPI_MCP_HEADERS), scoped by that integration's Capabilities (can be limited to read-only)
  • Access limited to the specific pages/databases explicitly connected to the integration, not the whole workspace
  • A separate bearer auth token when using the Streamable HTTP transport (--auth-token / AUTH_TOKEN)
  • Network access to the Notion API
Risks and side effects
  • OAuth tokens stored in plaintext locally, risk of exposure
  • Azure app registration required, misconfiguration can break service
  • Power Automate integration limited to solution-aware flows with manual triggers
  • Third-party server may introduce supply chain risk
  • If the integration is granted broad read/write capabilities and connected to many pages, that content is effectively exposed to the LLM, risking data leakage or unintended edits
  • Running with --unsafe-disable-auth removes bearer authentication on the HTTP transport, potentially making it reachable via DNS rebinding from pages a user visits — the README says to only use it on an isolated network
  • Multi-tenant token passthrough requires careful TLS/gateway configuration; misconfiguration risks leaking or misrouting Notion tokens between tenants
  • The README states this local server may be sunset in favor of the remote Notion MCP, and that issues/PRs here are not actively monitored, so long-term maintenance and security fixes are not guaranteed
  • Storing NOTION_TOKEN or OPENAPI_MCP_HEADERS directly in shared client config files risks leaking the secret
