name: notion description: Search, read, append to, and create Notion pages and databases via the Notion REST API. Use when the user mentions Notion, a page in their workspace, or wants to log something to a database. when_to_use: | Trigger when the user wants to read or write something in Notion — search a workspace, read a page, append blocks, query a database, create a page from a template, etc. connections: [notion] allowed_tools: [Bash] license: Apache-2.0 metadata: author: acedatacloud version: "1.0"

We drive the Notion API with curl + jq. The user's OAuth bearer token is in $NOTION_TOKEN; every call needs it plus the Notion-Version header.

Notion-Version is currently 2022-06-28 (the most recent stable). Bump this header when Notion ships a new version.

The user's connection only sees the pages and databases they explicitly shared with the integration when they authorized. If a search or page read returns nothing, the most likely cause is "the page was never shared with the integration" — surface that hint to the user.

Recipes

Verify auth (always run first)

curl -sS https://api.notion.com/v1/users/me \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  | jq '{id, name, type, bot: (.bot != null)}'

Search the workspace

curl -sS https://api.notion.com/v1/search \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  -H "Content-Type: application/json" \
  -d '{"query": "Q1 budget", "page_size": 10}' \
  | jq '.results[] | {id, type: .object, url, title: (.properties.title // .properties.Name)?.title?[0]?.plain_text // .child_page?.title}'

Read a page (metadata only)

curl -sS "https://api.notion.com/v1/pages/PAGE_ID" \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28"

Read a page's full content

curl -sS "https://api.notion.com/v1/blocks/PAGE_ID/children?page_size=100" \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  | jq '.results[] | {type, content: (.[.type] // {})}'

Append a paragraph to a page

curl -sS -X PATCH "https://api.notion.com/v1/blocks/PAGE_ID/children" \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  -H "Content-Type: application/json" \
  -d "$(jq -nc --arg text "Appended via the assistant." '
    {children: [{
      object: "block",
      type: "paragraph",
      paragraph: {rich_text: [{type:"text", text:{content:$text}}]}
    }]}')"

Query a database

curl -sS -X POST "https://api.notion.com/v1/databases/DATABASE_ID/query" \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  -H "Content-Type: application/json" \
  -d '{
    "filter": {"property": "Status", "select": {"equals": "Open"}},
    "sorts":  [{"property": "Updated", "direction": "descending"}],
    "page_size": 25
  }'

Create a page in a database

curl -sS -X POST "https://api.notion.com/v1/pages" \
  -H "Authorization: Bearer $NOTION_TOKEN" \
  -H "Notion-Version: 2022-06-28" \
  -H "Content-Type: application/json" \
  -d "$(jq -nc \
        --arg db "DATABASE_ID" \
        --arg title "New entry" \
        '{
          parent: {database_id: $db},
          properties: {
            Name:   {title: [{text: {content: $title}}]},
            Status: {select: {name: "Open"}}
          }
        }')"

Notes

• Notion's pagination is cursor-based: append start_cursor=$cursor to paginate, using the next_cursor from each response. Stop when has_more is false.
• Most write failures (400/404) come from a property type mismatch — e.g. sending {"select": "Open"} instead of {"select": {"name": "Open"}}. Read the database schema once via GET /v1/databases/<id> if unsure.

Record the output

After you successfully publish and obtain the live result URL, call the built-in publish_artifact tool ONCE so the user can track this deliverable in My Outputs:

publish_artifact(kind="document", channel="notion", title="<title>", url="<the REAL returned URL>", status="delivered")

Use the real returned URL — never fabricate one. Call it once per published item, only after delivery is confirmed; skip it (or use status="failed") if publishing failed. See _shared/artifacts.md.
