Notion Alternative MCP Tools for LangChain (13)
These 13 tools become available when you connect Notion Alternative to LangChain via MCP:
append_block
Requires the parent block/page ID and a JSON array of block objects. Each block must follow Notion's block schema: {"object":"block","type":"paragraph","paragraph":{"rich_text":[{"type":"text","text":{"content":"Hello"}}]}}. Common types: paragraph, heading_1, heading_2, heading_3, bulleted_list_item, numbered_list_item, to_do, toggle, code. Append blocks to a Notion page
create_comment
Requires the page ID and rich text content. Rich text follows Notion's format: [{"type":"text","text":{"content":"This looks great!"}}]. The comment will appear in the page's comment thread. Add a comment to a Notion page
create_database_row
Requires the database ID and a properties JSON object matching the database schema. Use get_database to see the property types and keys. Properties must follow Notion's format: {"Name":{"title":[{"text":{"content":"My Page"}}]},"Status":{"select":{"name":"Done"}}}. Create a new row (page) in a Notion database
get_database
), parent page and creation date. Provide the database ID (32-character hex or UUID format). Get details for a specific Notion database
get_me
Returns the bot name, ID and type. Use this to verify your integration token is working correctly and to see which bot identity the API calls will appear as. Get the authenticated Notion bot user
get_page
Does NOT return block content — use get_page_blocks for that. Provide the page ID. Get details for a specific Notion page
get_page_blocks
Each block has a type (paragraph, heading_1, heading_2, heading_3, bulleted_list_item, numbered_list_item, to_do, toggle, code, image, etc.) and content. Use this to read the actual text and media content of a page. Provide the page or block ID. Get blocks (content) of a Notion page
get_user
Provide the user ID from list_users. Get details for a specific Notion user
list_comments
Each comment includes the rich text content, author, creation date and parent reference. Useful for reviewing discussion threads and feedback on pages. List comments on a Notion page or block
list_database_rows
Returns pages matching the database schema with their property values. Optionally provide a filter object to narrow results (e.g. {"property":"Status","select":{"equals":"Done"}}) and sorts to order results. Use get_database first to understand the property schema. Query rows in a Notion database
list_users
Each user has an ID, name, avatar URL, email (if available) and type (person or bot). Useful for identifying who has access and who created content. List users in your Notion workspace
search
Optionally filter by text query (matches page titles and database names). Returns pages and databases with their properties, titles and parent info. Use this to discover content before querying or editing specific pages. Search pages and databases in Notion
update_page
Requires the page ID and a properties JSON object with the fields to change. Only provided properties will be updated. Follow Notion's property format: {"Status":{"select":{"name":"Done"}},"Priority":{"select":{"name":"High"}}}. Update properties of a Notion page
Example Prompts for Notion Alternative in LangChain
