Notion Private API MCP vs Notion MCP Server

notion_read

Run one Notion read operation by name. Nothing is modified. Call: { operation, payload } — payload carries that operation's fields. Common: search_pages { query }, get_page { page_id }, get_page_markdown { page_id }, query_database { database_id, where? }, get_block_children { block_id }. Responses are slimmed; pass verbose:true in payload for the raw Notion object. Every id field (page_id, block_id, database_id, view_id, …) also accepts a Notion URL, as copied from Share → Copy link. A block link's #fragment is used for block_id fields and a database link's ?v= for view_id fields. If the payload is malformed, the error response includes the schema + a working example so you can correct and retry in one round-trip. Call notion_describe(operation) ahead of time only for complex shapes (query_database filters).

notion_write

Run one Notion write operation by name. Archive, trash and delete operations remove content — confirm with the user before running them. Two ways to call: • Single: { operation: "set_page_title", payload: { page_id, title } } • Batch: { operation: "set_page_title", payload: { items: [{page_id, title}, ...], atomic?: false, idempotency_key?: "...", concurrency?: 3 } } create_page, append_blocks, update_block and update_page_markdown also take a markdown string. Responses are slimmed; pass verbose:true inside payload (single) or per item (batch) for the raw Notion object. Every id field (page_id, block_id, database_id, view_id, …) also accepts a Notion URL, as copied from Share → Copy link. If the payload is malformed, the error response includes the schema + a working example so you can correct and retry in one round-trip. Call notion_describe(operation) ahead of time only for complex shapes (block trees, database property definitions, batch_mixed_blocks).

notion_describe

Return the JSON Schema and a working example for one operation, plus which tool runs it (notion_read or notion_write). Use this BEFORE calling the operation when the payload shape is non-trivial (query filters, structured block trees, database property definitions). For simple ops, just call it — errors carry the schema.
