Implementation Reference

• src/handlers/helius.ts:387-400 (handler)

  The main handler function that executes the tool logic for 'helius_get_assets_by_creator'. It remaps the input parameters (creator to creatorAddress) and calls the Helius RPC method `getAssetsByCreator`.

  export const getAssetsByCreatorHandler = async (input: { creator: string, page?: number, limit?: number }): Promise<ToolResultSchema> => {
    try {
      // Fix the parameter name mismatch
      const params = {
        creatorAddress: input.creator, // Change creator to creatorAddress
        page: input.page || 1,
        limit: input.limit || 10
      };
      const assets = await (helius as any as Helius).rpc.getAssetsByCreator(params);
      return createSuccessResponse(`Assets by creator: ${JSON.stringify(assets, null, 2)}`);
    } catch (error) {
      return createErrorResponse(`Error getting assets by creator: ${error instanceof Error ? error.message : String(error)}`);
    }
  }
