Notion API 403 restricted_resource: the integration can see the page but not do that

Notion API 403 restricted_resource: the integration can see the page but not do that

TL;DR: Re-share the page with the integration and grant the capability the call needs (read vs edit vs insert). restricted_resource means the share exists but the permission level is too low for the operation. Check the integration capabilities in Notion settings after re-sharing.

The error

{"object":"error","status":403,"code":"restricted_resource","message":"Access to this resource is restricted."}

Fix it

1. In Notion, open the page, Share, and confirm the integration is listed.

Expected: The integration appears but with a low capability.

1. Change the share to grant the needed capability (e.g. Can edit for writes).

Expected: The share now shows the higher capability.

1. Retry the MCP tool call.

Expected: It succeeds.

When this applies

Notion MCP calls 403 with restricted_resource on pages or databases that are shared with the integration.

When this does NOT apply

404 objectnotfound means the page is not shared at all; share it first. 401 means the token is wrong.

Also seen as

• notion restricted_resource MCP
• Notion API 403 integration
• notion MCP cannot edit shared page

Why it happens

Notion shares carry capability levels. A page shared as read-only 403s any write call with restricted_resource, which looks like an auth failure but is really a permission level on the share.

Edge cases

• Database parent pages need sharing too, not just the database.
• Guests and free workspaces have their own capability limits.
• Re-sharing after a permission change is instant; no token change needed.
