Implementation Reference
- src/tools/retrieveBlock.ts:6-29 (handler)The main handler function for the 'retrieve_block' tool. It retrieves a specific Notion block by its ID using the Notion API and returns the block data as a formatted text response.
export const retrieveBlock = async ( params: RetrieveBlockParams ): Promise<CallToolResult> => { try { const response = await notion.blocks.retrieve({ block_id: params.blockId, }); return { content: [ { type: "text", text: "Block retrieved successfully! Note: If this block has children, use the retrieve_block_children endpoint to get the list of child blocks.", }, { type: "text", text: JSON.stringify(response, null, 2), }, ], }; } catch (error) { return handleNotionError(error); } }; - src/schema/blocks.ts:166-168 (schema)Zod schema defining the input parameters for the retrieve_block action: requires a blockId string.
export const RETRIEVE_BLOCK_SCHEMA = { blockId: z.string().describe("The ID of the block to retrieve"), }; - src/tools/blocks.ts:20-21 (registration)Dispatch registration in the blocks operation handler: maps the 'retrieve_block' action to the retrieveBlock function.
case "retrieve_block": return retrieveBlock(params.payload.params); - src/tools/index.ts:22-28 (registration)MCP tool registration for 'notion_blocks', which includes the 'retrieve_block' action via BLOCKS_OPERATION_SCHEMA and registerBlocksOperationTool handler.
// Register combined blocks operation tool server.tool( "notion_blocks", "Perform various block operations (retrieve, update, delete, append children, batch operations)", BLOCKS_OPERATION_SCHEMA, registerBlocksOperationTool ); - src/schema/blocks.ts:264-269 (schema)Definition of the 'retrieve_block' action within the BLOCKS_OPERATION_SCHEMA discriminated union.
